    Rename more bli_thread_obarrier(), _obroadcast().
    
    Details:
    - Renamed instances of bli_thread_obarrier() and bli_thread_obroadcast()
      that were made in the supmt-specific code commited to the 'amd'
      branch, which has now been merged with 'master'. Prior to the merge,
      'master' received commit c01d249, which applied these renamings to
      the existing, non-sup codebase.

    Updates, tweaks to runme.sh in test/1m4m.
    
    Details:
    - Made several updates to test/1m4m/runme.sh, including:
      - Added missing handling for 1m and 4m1a implementations when setting
        the BLIS_??_NT environment variables.
      - Added support for using numactl to run the test executables.
      - Several other cleanups.

    Warn user when auto-detection returns 'generic'.
    
    Details:
    - Added logic to configure that causes the script to output a warning
      to the user if/when "./configure auto" is run and the underlying
      hardware feature detection code is unable to identify the hardware.
      In these cases, the auto-detect code will return 'generic', which
      is likely not what the user expected, and a flag will be set so that
      a message is printed at the end of the configure output. (Thankfully,
      we don't expect this scenario to play out very often.) Thanks to
      Devin Matthews for suggesting this fix #384.

    Fix vectorized version of bli_amaxv (#382)
    
    * Fix vectorized version of bli_amaxv
    
    To match Netlib, i?amax should return:
    - the lowest index among equal values
    - the first NaN if one is encountered
    
    * Fix typos.
    
    * And another one...
    
    * Update ref. amaxv kernel too.
    
    * Re-enabled optimized amaxv kernels.
    
    Details:
    - Re-enabled the optimized, intrinsics-based amaxv kernels in the 'zen'
      kernel set for use in haswell, zen, zen2, knl, and skx subconfigs.
      These two kernels (for s and d datatypes) were temporarily disabled in
      e186d71 as part of issue #380. However, the key missing semantic
      properties that prompted the disabling of these kernels--returning the
      index of the *first* rather than of the last element with largest
      absolute value, and returning the index of the first NaN if one is
      encountered--were added as part of #382 thanks to Devin Matthews.
      Thus, now that the kernels are working as expected once more, this
      commit causes these kernels to once again be registered for the
      affected subconfigs, which effectively reverts all code changes
      included in e186d71.
    - Whitespace/formatting updates to new macros in bli_amaxv_zen_int.c.

    Disabled optimized amaxv kernels.
    
    Details:
    - Disabled use of optimized amaxv kernels, which use vector intrinsics
      for both 's' and 'd' datatypes. We disable these kernels because the
      current implementations fail to observe a semantic property of the
      BLAS i?amax_() subroutine, which is to return the index of the
      *first* element containing the maximum absolute value (that is, the
      first element if there exist two or more elements that contain the
      same value). With the optimized kernels disabled, the affected
      subconfigurations (haswell, zen, zen2, knl, and skx) will use the
      default reference implementations. Thanks to Mat Cross for reporting
      this issue via #380.
    - CREDITS file update.

    Added missing return to bli_thread_partition_2x2().
    
    Details:
    - Added a missing return statement to the body of an early case handling
      branch in bli_thread_partition_2x2(). This bug only affected cases
      where n_threads < 4, and even then, the code meant to handle cases
      where n_threads >= 4 executes and does the right thing, albeit using
      more CPU cycles than needed. Nonetheless, thanks to Kiran Varaganti
      for reporting this bug via issue #377.
    - Whitespace changes to bli_thread.c (spaces -> tabs).

    Merged test/sup, test/supmt into test/sup.
    
    Details:
    - Updated the Makefile, test_gemm.c, and runme.sh in test/sup to be able
      to compile and run both single-threaded and multithreaded experiments.
      This should help with maintenance going forward.
    - Created a test/sup/octave_st directory of scripts (based on the
      previous test/sup/octave scripts) as well as a test/sup/octave_mt
      directory (based on the previous test/supmt/octave scripts). The
      octave scripts are slightly different and not easily mergeable, and
      thus for now I'll maintain them separately.
    - Preserved the previous test/sup directory as test/sup/old/supst and
      the previous test/supmt directory as test/sup/old/supmt.

    Details:
    - Reran all existing single-threaded performance experiments comparing
      BLIS sup to other implementations (including the conventional code
      path within BLIS), using the latest versions (where appropriate).
    - Added multithreaded results for the three existing hardware types
      showcased in docs/PerformanceSmall.md: Kaby Lake, Haswell, and Epyc
      (Zen1).
    - Various minor updates to the text in docs/PerformanceSmall.md.
    - Updates to the octave scripts in test/sup/octave, test/supmt/octave.

    Updated sup[mt] Makefiles for variable dim ranges.
    
    Details:
    - Updated test/sup/Makefile and test/supmt/Makefile to allow specifying
      different problem size ranges for the drivers where one, two, or three
      matrix dimensions is large. This will facilitate the generation of
      more meaningful graphs, particularly when two dimensions are tiny.

    Details:
    - Optimized scripts in test/sup/octave and test/supmt/octave for use
      with octave 5.2.0 on Ubuntu 18.04.
    - Fixed stray 'end' keywords in gen_opsupnames.m and plot_l3sup_perf.m,
      which were not only unnecessary but also causing issues with versions
      5.x.

    Renamed bli_thread_obarrier(), _obroadcast().
    
    Details:
    - Renamed two bli_thread_*() APIs:
        bli_thread_obarrier()   -> bli_thread_barrier()
        bli_thread_obroadcast() -> bli_thread_broadcast()
      The 'o' was a leftover from when thrcomm_t objects tracked both
      "inner" and "outer" communicators. They have long since been
      simplified to only support the latter, and thus the 'o' is
      superfluous.

    Skip building thrinfo_t tree when mt is disabled.
    
    Details:
    - Return early from bli_thrinfo_sup_grow() if the thrinfo_t object
      address is equal to either &BLIS_GEMM_SINGLE_THREADED or
      &BLIS_PACKM_SINGLE_THREADED.
    - Added preprocessor logic to bli_l3_sup_thread_decorator() in
      bli_l3_sup_decor_single.c that (by default) disables code that
      creates and frees the thrinfo_t tree and instead passes
      &BLIS_GEMM_SINGLE_THREADED as the thrinfo_t pointer into the
      sup implementation.
    - The net effect of the above changes is that a small amount of
      thrinfo_t overhead is avoided when running small/skinny dgemm
      problems when BLIS is compiled with multithreading disabled.

    Fixed bug(s) in mt sup when single-threaded.
    
    Details:
    - Fixed a syntax bug in bli_l3_sup_decor_single.c as a result of
      changing function interface for the thread entry point function
      (of type l3supint_t).
    - Unfortunately, fixing the interface was not enough, as it caused
      a memory leak in the sba at bli_finalize() time. It turns out that,
      due to the new multithreading-capable variant code useing thrinfo_t
      objects--specifically, their calling of bli_thrinfo_grow()--we
      have to pass in a real thrinfo_t object rather than the global
      objects &BLIS_PACKM_SINGLE_THREADED or &BLIS_GEMM_SINGLE_THREADED.
      Thus, I inserted the appropriate logic from the OpenMP and pthreads
      versions so that single-threaded execution would work as intended
      with the newly upgraded variants.

    Support multithreading within the sup framework.
    
    Details:
    - Added multithreading support to the sup framework (via either OpenMP
      or pthreads). Both variants 1n and 2m now have the appropriate
      threading infrastructure, including data partitioning logic, to
      parallelize computation. This support handles all four combinations
      of packing on matrices A and B (neither, A only, B only, or both).
      This implementation tries to be a little smarter when automatic
      threading is requested (e.g. via BLIS_NUM_THREADS) in that it will
      recalculate the factorization in units of micropanels (rather than
      using the raw dimensions) in bli_l3_sup_int.c, when the final
      problem shape is known and after threads have already been spawned.
    - Implemented bli_?packm_sup_var2(), which packs to conventional row-
      or column-stored matrices. (This is used for the rrc and crc storage
      cases.) Previously, copym was used, but that would no longer suffice
      because it could not be parallelized.
    - Minor reorganization of packing-related sup functions. Specifically,
      bli_packm_sup_init_mem_[ab]() are called from within packm_sup_[ab]()
      instead of from the variant functions. This has the effect of making
      the variant functions more readable.
    - Added additional bli_thrinfo_set_*() static functions to bli_thrinfo.h
      and inserted usage of these functions within bli_thrinfo_init(), which
      previously was accessing thrinfo_t fields via the -> operator.
    - Renamed bli_partition_2x2() to bli_thread_partition_2x2().
    - Added an auto_factor field to the rntm_t struct in order to track
      whether automatic thread factorization was originally requested.
    - Added new test drivers in test/supmt that perform multithreaded sup
      tests, as well as appropriate octave/matlab scripts to plot the
      resulting output files.
    - Added additional language to docs/Multithreading.md to make it clear
      that specifying any BLIS_*_NT variable, even if it is set to 1, will
      be considered manual specification for the purposes of determining
      whether to auto-factorize via BLIS_NUM_THREADS.
    - Minor comment updates.

    Removed sorting on LDFLAGS in common.mk (#373).
    
    Details:
    - Removed a line of code in common.mk that passed LDFLAGS through the
      sort function. The purpose was not to sort the contents, but rather
      to remove duplicates. However, there is valid syntax in a string of
      linker flags that, when sorted, yields different/broken behavior.
      So I've removed the line in common.mk that sorts LDFLAGS. Also, for
      future use, I've added a new function, rm-dupls, that removes
      duplicates without sorting. (This function was based on code from a
      stackoverflow thread that is linked to in the comments for that
      code.) Thanks to Isuru Fernando for reporting this issue (#373).

    Removed 'attic/windows' (to prevent confusion).
    
    Details:
    - Finally removed 'attic/windows' and its contents. This directory once
      contained "proto" Windows support for BLIS, but we've since moved on
      to (thanks to Isuru Fernando) providing Windows DLL support via
      AppVeyor's build artifacts. Furthermore, since 'windows' was the only
      subdirectory within 'attic', the directory path would show up in
      GitHub's listing at https://github.com/flame/blis, which probably led
      to someone being confused about how BLIS provides Windows support. I
      assume (but don't know for sure) that nobody is using these files, so
      this is admittedly a case of shoot first and ask questions later.

    Fixed bugs in cblas_sdsdot(), sdsdot_().
    
    Details:
    - Fixed a bug in sdsdot_sub() that redundantly added the "alpha" scalar,
      named 'sb'. This value was already being added by the underlying
      sdsdot_() function. Thus, we no longer add 'sb' within sdsdot_sub().
      Thanks to Simon Lukas Märtens for reporting this bug via #367.
    - Fixed a second bug in order of typecasting intermediate products in
      sdsdot_(). Previously, the "alpha" scalar was being added after the
      "outer" typecast to float. However, the operation is supposed to first
      add the dot product to the (promoted) scalar and THEN downcast the sum
      to float. Thanks to Devin Matthews for catching this bug.

    Add prototypes for POWER9 reference kernels (#365)
    
    Updates and fixes to power9 subconfig.
    
    Details:
    - Register s,c,z reference gemm and trsm ukernels that assume elements
      of B have been broadcast.
    - Added prototypes for level-3 ukernels that assume elements of B have
      been broadcast. Also added prototype for an spackm function that
      employs a duplication/broadcast factor of 4.
    - Register virtual gemmtrsm ukernels that work with broadcasting of B.
    - Disable right-side hemm, symm, trmm, and trmm3 in bli_family_power9.h.
    - Thanks to Nicholai Tukanov for providing these updates.

    Added missing bli_l3_sup_thread_decorator() symbol.
    
    Details:
    - Defined dummy versions of bli_l3_sup_thread_decorator() for Openmp
      and pthreads so that those builds don't fail when performing shared
      library linking (especially for Windows DLLs via AppVeyor). For now,
      these dummy implementations of bli_l3_sup_thread_decorator() are
      merely carbon-copies of the implementation provided for single-
      threaded execution (ie: the one found in bli_l3_sup_decor_single.c).
      Thus, an OpenMP or pthreads build will be able to use the gemmsup
      code (including the new selective packing functionality), as it did
      before 39fa7136, even though it will not actually employ any
      multithreaded parallelism.

commit 39fa7136f4a4e55ccd9796fb79ad5f121b872ad9
Author: Field G. Van Zee <field@cs.utexas.edu>

    Added support for selective packing to gemmsup.
    
    Details:
    - Implemented optional packing for A or B (or both) within the sup
      framework (which currently only supports gemm). The request for
      packing either matrix A or matrix B can be made via setting
      environment variables BLIS_PACK_A or BLIS_PACK_B (to any
      non-zero value; if set, zero means "disable packing"). It can also
      be made globally at runtime via bli_pack_set_pack_a() and
      bli_pack_set_pack_b() or with individual rntm_t objects via
      bli_rntm_set_pack_a() and bli_rntm_set_pack_b() if using the expert
      interface of either the BLIS typed or object APIs. (If using the
      BLAS API, environment variables are the only way to communicate the
      packing request.)
    - One caveat (for now) with the current implementation of selective
      packing is that any blocksize extension registered in the _cntx_init
      function (such as is currently used by haswell and zen subconfigs)
      will be ignored if the affected matrix is packed. The reason is
      simply that I didn't get around to implementing the necessary logic
      to pack a larger edge-case micropanel, though this is entirely
      possible and should be done in the future.
    - Spun off the variant-choosing portion of bli_gemmsup_ref() into
      bli_gemmsup_int(), in bli_l3_sup_int.c.
    - Added new files, bli_l3_sup_packm_a.c, bli_l3_sup_packm_b.c, along
      with corresponding headers, in which higher-level packm-related
      functions are defined for use within the sup framework. The actual
      packm variant code resides in bli_l3_sup_packm_var.c.
    - Pass the following new parameters into var1n and var2m: packa, packb
      bool_t's, pointer to a rntm_t, pointer to a cntl_t (which is for now
      always NULL), and pointer to a thrinfo_t* (which for nowis the address
      of the global single-threaded packm thread control node).
    - Added panel strides ps_a and ps_b to the auxinfo_t structure so that
      the millikernel can query the panel stride of the packed matrix and
      step through it accordingly. If the matrix isn't packed, the panel
      stride of interest for the given millikernel will be set to the
      appropriate value so that the mkernel may step through the unpacked
      matrix as it normally would.
    - Modified the rv_6x8m and rv_6x8n millikernels to read the appropriate
      panel strides (ps_a and ps_b, respectively) instead of computing them
      on the fly.
    - Spun off the environment variable getting and setting functions into
      a new file, bli_env.c (with a corresponding prototype header). These
      functions are now used by the threading infrastructure (e.g.
      BLIS_NUM_THREADS, BLIS_JC_NT, etc.) as well as the selective packing
      infrastructure (e.g. BLIS_PACK_A, BLIS_PACK_B).
    - Added a static initializer for mem_t objects, BLIS_MEM_INITIALIZER.
    - Added a static initializer for pblk_t objects, BLIS_PBLK_INITIALIZER,
      for use within the definition of BLIS_MEM_INITIALIZER.
    - Moved the global_rntm object to bli_rntm.c and extern it where needed.
      This means that the function bli_thread_init_rntm() was renamed to
      bli_rntm_init_from_global() and relocated accordingly.
    - Added a new bli_pack.c function, which serves as the home for
      functions that manage the pack_a and pack_b fields of the global
      rntm_t, including from environment variables, just as we have
      functions to manage the threading fields of the global rntm_t in
      bli_thread.c.
    - Reorganized naming for files in frame/thread, which mostly involved
      spinning off the bli_l3_thread_decorator() functions into their own
      files. This change makes more sense when considering the further
      addition of bli_l3_sup_thread_decorator() functions (for now limited
      only to the single-threaded form found in the  _single.c file).
    - Explicitly initialize the reference sup handlers in both
      bli_cntx_init_haswell.c and bli_cntx_init_zen.c so that it's more
      obvious how to customize to a different handler, if desired.
    - Removed various snippets of disabled code.
    - Various comment updates.

    Fixed blastest failure for 'generic' subconfig.
    
    Details:
    - Fixed a subtle and complicated bug that only manifested via the BLAS
      test drivers in the generic subconfiguration, and possibly any other
      subconfiguration that did not register complex-domain gemm ukernels,
      or registered ONLY real-domain ukernels as row-preferential. This is
      a long story, but it boils down to an exception to the "transpose the
      operation to bring storage of C into agreement with ukernel pref"
      optimization in bli_hemm_front.c and bli_symm_front.c sabotaging the
      proper functioning of the 1m method, but only when the imaginary
      component of beta is zero. See the comments in issue #342 for more
      details. Thanks to Dave Love for identifying the commit in which this
      bug was introduced, and other feedback related to this bug.

    Fixed obscure bug in bli_acquire_mpart_[mn]dim().
    
    Details:
    - Fixed a bug in bli_acquire_mpart_mdim(), bli_acquire_mpart_ndim(),
      and bli_acquire_mpart_mndim() that allowed the use of a blocksize b
      that is too large given the current row/column index (i.e., the i/j
      argument) and the size of the dimension being partitioned (i.e., the
      m/n argument). This bug only affected backwards partitioning/motion
      through the dimension and was the result of a misplaced conditional
      check-and-redirect to the backwards code path. It should be noted
      that this bug was discovered not because it manifested the way it
      could (thanks to the callers in BLIS making sure to always pass in
      the "correct" blocksize b), but could have manifested if the
      functions were used by 3rd party callers. Thanks to Minh Quan Ho for
      reporting the bug via issue #363.

    Details:
    - Fixed a copy-paste bug in the new bli_spackm_6xk_bb4_ref() that
      manifested as failures in single-precision real level-3 operations.
      Also replaced the duplication factor constants with a const-qualifed
      varialbe, dfac, so that this won't happen again.
    - Changed NC for single-precision real from 4080 to 8160 so that the
      packed matrix B will have the same byte footprint in both single
      and double real.

    Various fixes to support packing duplication in B.
    
    Details:
    - Added cpp macros to trmm and trmm3 front-ends to optionally force
      those operations to be cast so the structured matrix is on the left.
      symm and hemm already had such macros, but these too were renamed so
      that the macros were individual to the operation. We now have four
      such macros:
        #define BLIS_DISABLE_HEMM_RIGHT
        #define BLIS_DISABLE_SYMM_RIGHT
        #define BLIS_DISABLE_TRMM_RIGHT
        #define BLIS_DISABLE_TRMM3_RIGHT
      Also, updated the comments in the symm and hemm front-ends related to
      the first two macro guards, and added corresponding comments to the
      trmm and trmm3 front-ends for the latter two guards. (They all
      functionally do the same thing, just for their specific operations.)
      Thanks to Jeff Hammond for reporting the bugs that led me to this
      change (via #359).
    - Updated config/old/haswellbb subconfiguration (used to debug issues
      related to duplicating B during packing) to register: a packing
      kernel for single-precision real; gemmbb ukernels for s, c, and z;
      trsmbb ukernels for s, c, and z; gemmtrsmbb virtual ukrnels for s, c
      and z; and to use non-default cache and register blocksizes for s, c,
      and z datatypes. Also declared prototypes for all of the gemmbb,
      trsmbb, and gemmtrsmbb ukernel functions within the
      bli_cntx_init_haswellbb() function. This should, once applied to the
      power9 configuration, fix the remaining issues in #359.
    - Defined bli_spackm_6xk_bb4_ref(), which packs single reals with a
      duplication factor of 4. This function is defined in the same file as
      bli_dpackm_6xk_bb2_ref() (bli_packm_cxk_bb_ref.c).

    Fixed failing testsuite gemmtrsm_ukr for power9.
    
    Details:
    - Added code that fixes false failures in the gemmtrsm_ukr module of the
      testsuite. The tests were failing because the computation (bli_gemv())
      that performs the numerical check was not able to properly travserse
      the matrix operands bx1 and b11 that are views into the micropanel of
      B, which has duplicated/broadcast elements under the power9 subconfig.
      (For example, a micropanel of B with duplication factor of 2 needs to
      use a column stride of 2; previously, the column stride was being
      interpreted as 1.)
    - Defined separate bli_obj_set_row_stride() and bli_obj_set_col_stride()
      static functions in bli_obj_macro_defs.h. (Previously, only the
      function bli_obj_set_strides() was defined. Amazing to think that we
      got this far without these former functions.)
    - Updated/expounded upon comments.

    Fixed latent testsuite ukr module bugs for power9.
    
    Details:
    - Fixed a latent bug in the testsuite ukernel modules (gemm, trsm, and
      gemmtrsm) that only manifested once we began running with parameters
      that mimic those of power9. The problem was rooted in the way those
      modules were creating objects (and thus allocating memory) for the
      micropanel operands to the microkernel being tested. Since power9
      duplicates/broadcasts elements of B in memory, we needed an easy way
      of asking for more than one storage element per logical element in
      the matrix. I incorrectly expressed this as:
    
        bli_obj_create( datatype, k, n, ldbp, 1, &bp );
    
      The problem here is that bli_obj_create() is exceedingly efficient
      at calculating the size it passes to malloc() and doesn't allocate a
      full leading dimension's worth of elements for the last column (or
      row, in this example). This would normally not bother anyone since
      you're not supposed to access that memory anyway. But here, my
      attempted "hack" for getting extra elements was insufficient, and
      needed to be changed to:
    
        bli_obj_create( datatype, k, ldbp, ldbp, 1, &bp );
    
      That is, the extra elements needed to be baked into the dimensions of
      the matrix object in order to have the intended effect on the number
      of elements actually allocated. Thanks to Jeff Hammond for reporting
      this bug.
    - Fixed a typically harmless memory leak in the aforementioned test
      modules (the objects for the packed micropanels were not being freed).
    - Updated/expanded a common comment across all three ukr test modules.

    POWER9 DGEMM  (#355)
    
    Implemented and registered power9 dgemm ukernel.
    
    Details:
    - Implemented 12x6 dgemm microkernel for power9. This microkernel
      assumes that elements of B have been duplicated/broadcast during the
      packing step. The microkernel uses a column orientation for its
      microtile vector registers and thus implements column storage and
      general stride IO cases. (A row storage IO case via in-register
      transposition may be added at a future date.) It should be noted that
      we recommend using this microkernel with gcc and *not* xlc, as issues
      with the latter cropped up during development, including but not
      limited to slightly incompatible vector register mnemonics in the GNU
      extended inline assembly clobber list.

    Call bli_syrk_small() before error checking.
    
    Details:
    - In bli_syrk_front(), moved the conditional call to bli_syrk_check()
      (if error checking is enabled) and the conditional scaling of C by
      beta (if alpha is zero) so that they occur after, instead of before,
      the call to bli_syrk_small(). This sequencing now matches that of
      bli_gemm_small() in bli_gemm_front() and bli_trsm_small() in
      bli_trsm_front().

    When manual config is blacklisted, output error.
    
    Details:
    - Fixed and adjusted the logic in configure so that a more informative
      error message is output when a user runs './configure ... <conf>' and
      <conf> is present in the configuration blacklist. Previously, this
      particular set of conditions would result in the message:
    
        'user-specified configuration '' is NOT registered!
    
      That is, the error message mis-identified the targeted configuration
      as the empty string, and (more importantly) mis-identifies the
      problem. Thanks to Tze Meng Low for reporting this issue.
    - Fixed a nearby error messages somewhat unrelated to the issue above.
      Specifically, the wrong string was being printed when the error
      message was identifying an auto-detected configuration that did not
      appear to be registered.

    Changed -march=znver2 to =znver1 for clang on zen2.
    
    Details:
    - In config/zen2/make_defs.mk, changed the -march= flag so that
      -march=znver1 is used instead of -march=znver2 when CC_VENDOR is
      clang. (The gcc branch attempts to differentiate between various
      versions, but the equivalent version cutoffs for clang are not
      yet known by us, so we have to use a single flag for all versions
      of clang. Hopefully -march=znver1 is new enough. If not, we'll
      fall back to -march=bdver4 -mno-fma4 -mno-tbm -mno-xop -mno-lwp.)
      This issue was discovered thanks to AppVeyor.

    Code review + tweaks to AMD's AOCL 2.0 PR (#349).
    
    Details:
    - NOTE: This is a merge commit of 'master' of git://github.com/amd/blis
      into 'amd-master' of flame/blis.
    - Fixed a bug in the downstream value of BLIS_NUM_ARCHS, which was
      inadvertantly not incremented when the Zen2 subconfiguration was
      added.
    - In bli_gemm_front(), added a missing conditional constraint around the
      call to bli_gemm_small() that ensures that the computation precision
      of C matches the storage precision of C.
    - In bli_syrk_front(), reorganized and relocated the notrans/trans logic
      that existed around the call to bli_syrk_small() into bli_syrk_small()
      to minimize the calling code footprint and also to bring that code
      into stylistic harmony with similar code in bli_gemm_front() and
      bli_trsm_front(). Also, replaced direct accessing of obj_t fields with
      proper accessor static functions (e.g. 'a->dim[0]' becomes
      'bli_obj_length( a )').
    - Added #ifdef BLIS_ENABLE_SMALL_MATRIX guard around prototypes for
      bli_gemm_small(), bli_syrk_small(), and bli_trsm_small(). This is
      strictly speaking unnecessary, but it serves as a useful visual cue to
      those who may be reading the files.
    - Removed cpp macro-protected small matrix debugging code from
      bli_trsm_front.c.
    - Added a GCC_OT_9_1_0 variable to build/config.mk.in to facilitate gcc
      version check for availability of -march=znver2, and added appropriate
      support to configure script.
    - Cleanups to compiler flags common to recent AMD microarchitectures in
      config/zen/amd_config.mk, including: removal of -march=znver1 et al.
      from CKVECFLAGS (since the -march flag is added within make_defs.mk);
      setting CRVECFLAGS similarly to CKVECFLAGS.
    - Cleanups to config/zen/bli_cntx_init_zen.c.
    - Cleanups, added comments to config/zen/make_defs.mk.
    - Cleanups to config/zen2/make_defs.mk, including making use of newly-
      added GCC_OT_9_1_0 and existing GCC_OT_6_1_0 to choose the correct
      set of compiler flags based on the version of gcc being used.
    - Reverted downstream changes to test/test_gemm.c.
    - Various whitespace/comment changes.

    Added support for pre-broadcast when packing B.
    
    Details:
    - Added support for being able to duplicate (broadcast) elements in
      memory when packing matrix B (ie: the left-hand operand) in level-3
      operations. This turns out advantageous for some architectures that
      can afford the cost of the extra bandwidth and somehow benefit from
      the pre-broadcast elements (and thus being able to avoid using
      broadcast-style load instructions on micro-rows of B in the gemm
      microkernel).
    - Support optionally disabling right-side hemm and symm. If this occurs,
      hemm_r is implemented in terms of hemm_l (and symm_r in terms of
      symm_l). This is needed when broadcasting during packing because the
      alternative--supporting the broadcast of B while also allowing matrix
      B to be Hermitian/symmetric--would be an absolute mess.
    - Support alignment factors for packed blocks of A, B, and C separately
      (as well as for general-purpose buffers). In addition, we support
      byte offsets from those alignment values (which is different from
      aligning by align+offset bytes to begin with). The default alignment
      values are BLIS_PAGE_SIZE in all four cases, with the offset values
      defaulting to zero.
    - Pass pack_t schema into bli_?packm_cxk() so that it can be then passed
      into the packm kernel, where it will be needed by packm kernels that
      perform broadcasts of B, since the idea is that we *only* want to
      broadcast when packing micropanels of B and not A.
    - Added definition for variadic bli_cntx_set_l3_vir_ukrs(), which can be
      used to set custom virtual level-3 microkernels in the cntx_t, which
      would typically be done in the bli_cntx_init_*() function defined in
      the subconfiguration of interest.
    - Added a "broadcast B" kernel function for use with NP/NR = 12/6,
      defined in in ref_kernels/1m/bli_packm_cxk_bb_ref.c.
    - Added a gemm, gemmtrsm, and trsm "broadcast B" reference kernels
      defined in ref_kernels/3/bb. (These kernels have been tested with
      double real with NP/NR = 12/6.)
    - Added #ifndef ... #endif guards around several macro constants defined
      in frame/include/bli_kernel_macro_defs.h.
    - Defined a few "broadcast B" static functions in
      frame/include/level0/bb for use by "broadcast B"-style packm reference
      kernels. For now, only the real domain kernels are tested and fully
      defined.
    - Output the alignment and offset values for packed blocks of A and B
      in the testsuite's "BLIS configuration info" section.
    - Comment updates to various files.
    - Bumped so_version to 3.0.0.

      increment was equal to 1.
    - Disabled the building of rrc, rcr, rcc, crr, crc, and ccr storage
      combinations for blissup drivers in test/sup. This helps make the
      building of drivers complete sooner.
    - Trivial changes to test/sup/runme.sh.

    Changed test/sup alpha to 1; test libxsmm+netlib.
    
    Details:
    - Changed the value of alpha to 1.0 in test/sup/test_gemm.c. This is
      needed because libxsmm currently only optimizes gemm operations where
      alpha is unit (and beta is unit or zero).
    - Adjusted the test/sup/Makefile to test libxsmm with netlib BLAS as its
      fallback library. This is the library that will be called the
      problem dimensions are deemed too large, or any other criteria for
      optimization are not met. (This was done not because it is realistic,
      but rather so that it would be very clear when libxsmm ceased handling
      gemm calls internally when the data are graphed.)

      libxsmm's documentation isn't clear on whether it is even *trying* to
      provide BLAS API compatibility, and I got tired of trying to figure it
      out.
    - Added missing -ldl in LDFLAGS when linking against libxsmm.

    - Modified test/sup/Makefile to build drivers that test the performance

    - Modified test/sup/runme.sh to run aforementioned drivers.
    - Modified test/sup/test_gemm.c so that problem sizes are tested in
      reverse order (from largest to smallest). This can help avoid certain
      situations where the CPU frequency does not immediately throttle up
      to its maximum. Thanks to Robert van de Geijn for recommending this
      fix.

    Pacify 'restrict' warning in gemmtrsm4m1 ref ukr.
    
    Details:
    - Previously, some versions of gcc would complain that the same
      pointer, one_r, is being passed in for both alpha and beta in the
      fourth call to the real gemm ukernel in bli_gemmtrsm4m1_ref.c. This
      is understandable since the compiler knows that the real gemm ukernel
      qualifies all of its floating-point arguments (including alpha and
      beta) with restrict. A small hack has been inserted into the file
      that defines a new variable to store the value 1.0, which is now used
      in lieu of one_r for beta in the fourth call to the real gemm ukernel,
      which should pacify the compiler now. Thanks to Dave Love for
      reporting this issue (#328) and for Devin Matthews for offering his
      'restrict' expertise.

    Add -march support for specific gcc version ranges.
    
    Details:
    - Added logic to configure that checks the version of the compiler
      against known version ranges that could cause problems later in the
      build process. For example, versions of gcc older than 4.9.0 use
      different -march labels than version 4.9.0 or later
      ('-march=corei7-avx' vs '-march=sandybridge', respectively).
      Similarly, before 6.1, compilation on Zen was possible, but you
      need to start with -march=bdver4 and then disable instruction sets
      that were discarded during the transition from Excavator to Zen. So
      now, configure substitutes 'yes'/'no' values into anchors in
      config.mk.in, which sets various make variables (e.g. GCC_OT_4_9_0),
      which can be accessed and branched upon by the various
      configurations' make_defs.mk files when setting their compiler flags.
    - Updated config/haswell/make_defs.mk to branch on GCC_OT_4_9_0.
    - Updated config/sandybridge/make_defs.mk to branch on GCC_OT_4_9_0.
    - Updated config/zen/make_defs.mk to branch on GCC_OT_6_1_0.

    - Added a new standalone test driver directory named '1m4m' that can
      build and run performance experiments for BLIS 1m, 4m1a, assembly,
      OpenBLAS, and the vendor library (MKL). This new driver directory
      was used to regenerate performance results for the 1m paper.
    - Added alternate (commented-out) cache blocksizes to
      config/haswell/bli_cntx_init_haswell.c. These blocksizes tend to
      work well on an a 12-core Intel Xeon E5-2650 v3.

    - Updated the '-march=corei7-avx' flag in the sandybridge subconfig
      to '-march=sandybridge' and the '-march=core-avx2' flag in the
      haswell subconfig to '-march=haswell'. The older flags were used
      by older versions of gcc and should have been updated to the newer
      forms a long time ago. (The older flags were clearly working, even
      though they are no longer documented in the gcc man page.)

    Fixed thrinfo_t printing bug for small problems.
    
    Details:
    - Fixed a bug in bli_l3_thrinfo_print_gemm_paths() and
      bli_l3_thrinfo_print_trsm_paths(), defined in bli_l3_thrinfo.c,
      whereby subnodes of the thrinfo_t tree are "dereferenced" near the
      beginning of the functions, which may lead to segfaults in certain
      situations where the thread tree was not fully formed because the
      matrix problem was too small for the level of parallelism specified.
      (That is, too small because some problems were assigned no work due
      to the smallest units in the m and n dimensions being defined by the
      register blocksizes mr and nr.) The fix requires several nested levels
      of if statements, and this is one of those few instances where use of
      goto statements results in (mostly) prettier code, especially in the
      case of _gemm_paths(). And while it wasn't necessary, I ported this
      goto usage to the loop body that prints the thrinfo_t work_id and
      comm_id values for each thread. Thanks to Nicholai Tukanov for helping
      to find this bug.

      containing the mpnpkp results do not need to be preprocessed in order
      to plot half the problem size range (ie: up to 400 instead of the

    Inadvertantly hidden xerbla_() in blastest (#313).
    
    Details:
    - Attempted a fix to issue #313, which reports that when building only
      a shared library (ie: static library build is disabled), running the
      BLAS test drivers can fail because those drivers provide their own
      local version of xerbla_() as a clever (albeit still rather hackish)
      way of checking the error codes that result from the individual tests.
      This local xerbla_() function is never found at link-time because the
      BLAS test drivers' Makefile imports BLIS compilation flags via the
      get-user-cflags-for() function, which currently conveys the
      -fvisibility=hidden flag, which hides symbols unless they are
      explicitly annotated for export. The -fvisibility=hidden flag was
      only ever intended for use when building BLIS (not for applications),
      and so the attempted solution here is to omit the symbol export
      flag(s) from get-user-cflags-for() by storing the symbol export
      flag(s) to a new BULID_SYMFLAGS variable instead of appending it
      to the subconfigurations' CMISCFLAGS variable (which is returned by
      every get-*-cflags-for() function). Thanks to M. Zhou for reporting
      this issue and also to Isuru Fernando for suggesting the fix.
    - Renamed BUILD_FLAGS to BUILD_CPPFLAGS to harmonize with the newly
      created BUILD_SYMFLAGS.
    - Fixed typo in entry for --export-shared flag in 'configure --help'
      text.

    Increased MT sup threshold for double to 180.
    
    Details:
    - Increased the double-precision real MT threshold (which controls
      whether the sup implementation kicks for smaller m dimension values)
      from 80 to 180, and this change was made for both haswell and zen
      subconfigurations. This is less about the m dimension in particular
      and more about facilitating a smoother performance transition when
      m = n = k.

        #define _POSIX_C_SOURCE 200809L
        #endif
      to bli_system.h so that an application that uses BLIS (specifically,

      #define the macro itself (either on the command line or in the code
      that includes blis.h) in order to activate things like the pthreads.

    Minor bugfixes in sup dgemm implementation.
    
    Details:
    - Fixed an obscure but in the bli_dgemmsup_rv_haswell_asm_5x8n() kernel
      that only affected the beta == 0, column-storage output case. Thanks
      to the BLAS test drivers for catching this bug.
    - Previously, bli_gemmsup_ref_var1n() and _var2m() were returning if
      k = 0, when the correct action would be to scale by beta (and then
      return). Thanks to the BLAS test drivers to catching this bug.
    - Changed the sup threshold behavior such that the sup implementation
      only kicks in if a matrix dimension is strictly less than (rather than
      less than or equal to) the threshold in question.
    - Initialize all thresholds to zero (instead of 10) by default in
      ref_kernels/bli_cntx_ref.c. This, combined with the above change to
      threshold testing means that calls to BLIS or BLAS with one or more
      matrix dimensions of zero will no longer trigger the sup
      implementation.
    - Added disabled debugging output to frame/3/bli_l3_sup.c (for future
      use, perhaps).

    Ceased use of BLIS_ENABLE_SUP_MR/NR_EXT macros.
    
    Details:
    - Removed already limited use of the BLIS_ENABLE_SUP_MR_EXT and
      BLIS_ENABLE_SUP_NR_EXT macros in bli_gemmsup_ref_var1n() and
      bli_gemmsup_ref_var2m(). Their purpose was merely to avoid a long
      conditional that would determine whether to allow the last iteration
      to be merged with the second-to-last iteration. Functionally, the
      macros were not needed, and they ended up causing problems when
      building configuration families such as intel64 and x86_64.

    Details:
    - Fixed an incorrectly-named macro guard that is intended to allow
      disabling of the sup framework via the configure option
      --disable-sup-handling. In this case, the preprocessor macro,
      BLIS_DISABLE_SUP_HANDLING, was still named by its name from an older
      uncommitted version of the code (BLIS_DISABLE_SM_HANDLING).

    Implemented gemm on skinny/unpacked matrices.
    
    Details:
    - Implemented a new sub-framework within BLIS to support the management
      of code and kernels that specifically target matrix problems for which
      at least one dimension is deemed to be small, which can result in long
      and skinny matrix operands that are ill-suited for the conventional
      level-3 implementations in BLIS. The new framework tackles the problem
      in two ways. First the stripped-down algorithmic loops forgo the
      packing that is famously performed in the classic code path. That is,
      the computation is performed by a new family of kernels tailored
      specifically for operating on the source matrices as-is (unpacked).
      Second, these new kernels will typically (and in the case of haswell
      and zen, do in fact) include separate assembly sub-kernels for
      handling of edge cases, which helps smooth performance when performing
      problems whose m and n dimension are not naturally multiples of the
      register blocksizes. In a reference to the sub-framework's purpose of
      supporting skinny/unpacked level-3 operations, the "sup" operation
      suffix (e.g. gemmsup) is typically used to denote a separate namespace
      for related code and kernels. NOTE: Since the sup framework does not
      perform any packing, it targets row- and column-stored matrices A, B,
      and C. For now, if any matrix has non-unit strides in both dimensions,
      the problem is computed by the conventional implementation.
    - Implemented the default sup handler as a front-end to two variants.
      bli_gemmsup_ref_var2() provides a block-panel variant (in which the
      2nd loop around the microkernel iterates over n and the 1st loop
      iterates over m), while bli_gemmsup_ref_var1() provides a panel-block
      variant (2nd loop over m and 1st loop over n). However, these variants
      are not used by default and provided for reference only. Instead, the
      default sup handler calls _var2m() and _var1n(), which are similar
      to _var2() and _var1(), respectively, except that they defer to the
      sup kernel itself to iterate over the m and n dimension, respectively.
      In other words, these variants rely not on microkernels, but on
      so-called "millikernels" that iterate along m and k, or n and k.
      The benefit of using millikernels is a reduction of function call
      and related (local integer typecast) overhead as well as the ability
      for the kernel to know which micropanel (A or B) will change during
      the next iteration of the 1st loop, which allows it to focus its
      prefetching on that micropanel. (In _var2m()'s millikernel, the upanel
      of A changes while the same upanel of B is reused. In _var1n()'s, the
      upanel of B changes while the upanel of A is reused.)
    - Added a new configure option, --[en|dis]able-sup-handling, which is
      enabled by default. However, the default thresholds at which the
      default sup handler is activated are set to zero for each of the m, n,
      and k dimensions, which effectively disables the implementation. (The
      default sup handler only accepts the problem if at least one dimension
      is smaller than or equal to its corresponding threshold. If all
      dimensions are larger than their thresholds, the problem is rejected
      by the sup front-end and control is passed back to the conventional
      implementation, which proceeds normally.)
    - Added support to the cntx_t structure to track new fields related to
      the sup framework, most notably:
      - sup thresholds: the thresholds at which the sup handler is called.
      - sup handlers: the address of the function to call to implement
        the level-3 skinny/unpacked matrix implementation.
      - sup blocksizes: the register and cache blocksizes used by the sup
        implementation (which may be the same or different from those used
        by the conventional packm-based approach).
      - sup kernels: the kernels that the handler will use in implementing
        the sup functionality.
      - sup kernel prefs: the IO preference of the sup kernels, which may
        differ from the preferences of the conventional gemm microkernels'
        IO preferences.
    - Added a bool_t to the rntm_t structure that indicates whether sup
      handling should be enabled/disabled. This allows per-call control
      of whether the sup implementation is used, which is useful for test
      drivers that wish to switch between the conventional and sup codes
      without having to link to different copies of BLIS. The corresponding
      accessor functions for this new bool_t are defined in bli_rntm.h.
    - Implemented several row-preferential gemmsup kernels in a new
      directory, kernels/haswell/3/sup. These kernels include two general
      implementation types--'rd' and 'rv'--for the 6x8 base shape, with
      two specialized millikernels that embed the 1st loop within the kernel
      itself.
    - Added ref_kernels/3/bli_gemmsup_ref.c, which provides reference
      gemmsup microkernels. NOTE: These microkernels, unlike the current
      crop of conventional (pack-based) microkernels, do not use constant
      loop bounds. Additionally, their inner loop iterates over the k
      dimension.
    - Defined new typedef enums:
      - stor3_t: captures the effective storage combination of the level-3
        problem. Valid values are BLIS_RRR, BLIS_RRC, BLIS_RCR, etc. A
        special value of BLIS_XXX is used to denote an arbitrary combination
        which, in practice, means that at least one of the operands is
        stored according to general stride.
      - threshid_t: captures each of the three dimension thresholds.
    - Changed bli_adjust_strides() in bli_obj.c so that bli_obj_create()
      can be passed "-1, -1" as a lazy request for row storage. (Note that
      "0, 0" is still accepted as a lazy request for column storage.)
    - Added support for various instructions to bli_x86_asm_macros.h,
      including imul, vhaddps/pd, and other instructions related to integer
      vectors.
    - Disabled the older small matrix handling code inserted by AMD in
      bli_gemm_front.c, since the sup framework introduced in this commit
      is intended to provide a more generalized solution.
    - Added test/sup directory, which contains standalone performance test
      drivers, a Makefile, a runme.sh script, and an 'octave' directory
      containing scripts compatible with GNU Octave. (They also may work
      with matlab, but if not, they are probably close to working.)
    - Reinterpret the storage combination string (sc_str) in the various
      level-3 testsuite modules (e.g. src/test_gemm.c) so that the order
      of each matrix storage char is "cab" rather than "abc".
    - Comment updates in level-3 BLAS API wrappers in frame/compat.

    Support row storage in Eigen gemm test/3 driver.
    
    Details:
    - Added preprocessor branches to test/3/test_gemm.c to explicitly
      support row-stored matrices. Column-stored matrices are also still
      supported (and is the default for now). (This is mainly residual work
      leftover from initial integration of Eigen into the test drivers, so
      if we ever want to test Eigen with row-stored matrices, the code will
      be ready to use, even if it is not yet integrated into the Makefile
      in test/3.)

    GNU-like handling of installation prefix et al.
    
    Details:
    - Changed the default installation prefix from $HOME/lib to /usr/local.
    - Modified the way configure internally handles the prefix, libdir,
      includedir, and sharedir (and also added an --exec-prefix option).
      The defaults to these variables are set as follows:
        prefix:      /usr/local
        exec_prefix: ${prefix}
        libdir:      ${exec_prefix}/lib
        includedir:  ${prefix}/include
        sharedir:    ${prefix}/share
      The key change, aside from the addition of exec_prefix and its use to
      define the default to libdir, is that the variables are substituted
      into config.mk with quoting that delays evaluation, meaning the
      substituted values may contain unevaluated references to other
      variables (namely, ${prefix} and ${exec_prefix}). This more closely
      follows GNU conventions, including those used by GNU autoconf, and
      also allows make to override any one of the variables *after*
      configure has already been run (e.g. during 'make install').
    - Updates to build/config.mk.in pursuant to above changes.
    - Updates to output of 'configure --help' pursuant to above changes.
    - Updated docs/BuildSystem.md to reflect the new default installation
      prefix, as well as mention EXECPREFIX and SHAREDIR.
    - Changed the definitions of the UNINSTALL_OLD_* variables in the
      top-level Makefile to use $(wildcard ...) instead of 'find'. This
      was motivated by the new way of handling prefix and friends, which
      leads to the 'find' command being run on /usr/local (by default),
      which can take a while almost never yielding any benefit (since the
      user will very rarely use the uninstall-old targets).
    - Removed periods from the end of descriptive output statements (i.e.,
      non-verbose output) since those statements often end with file or
      directory paths, which get confusing to read when puctuated by a
      period.
    - Trival change to 'make showconfig' output.
    - Removed my name from 'configure --help'. (Many have contributed to it
      over the years.)
    - In configure script, changed the default state of threading_model
      variable from 'no' to 'off' to match that of debug_type, where there
      are similarly more than two valid states. ('no' is still accepted
      if given via the --enable-debug= option, though it will be
      standardized to 'off' prior to config.mk being written out.)
    - Minor variable name change in flatten-headers.py that was intended for
      32812ff.
    - CREDITS file update.

    Fix for single rank crash with HPL application. When computing offset of C buffer, as integer variables are used for a row and column index, the intermediate result value overflows and a negative value gets added to the buffer, when the negative value is too large it would index the buffer out of the range resulting in segmentation fault. Although the crash is a result of dgemm kernel, added similar code in sgemm kernel also.

    Minor bugfix to flatten-headers.py.
    
    Details:
    - Fixed a minor bug in flatten-headers.py whereby the script, upon
      encountering a #include directive for the root header file, would
      erroneously recurse and inline the conents of that root header.
      The script has been modified to avoid recursion into any headers
      that share the same name as the root-level header that was passed
      into the script. (Note: this bug didn't actually manifest in BLIS,
      so it's merely a precaution for usage of flatten-headers.py in other
      contexts.)

    Use void_fp for function pointers instead of void*.
    
    Change void*-typed function pointers to void_fp.
    - Updated all instances of void* variables that store function pointers
      to variables of a new type, void_fp. Originally, I wanted to define
      the type of void_fp as "void (*void_fp)( void )"--that is, a pointer
      to a function with no return value and no arguments. However, once
      I did this, I realized that gcc complains with incompatible pointer
      type (-Wincompatible-pointer-types) warnings every time any such a
      pointer is being assigned to its final, type-accurate function
      pointer type. That is, gcc will silently typecast a void* to
      another defined function pointer type (e.g. dscalv_ker_ft) during
      an assignment from the former to the latter, but the same statement
      will trigger a warning when typecasting from a void_fp type. I suspect
      an explicit typecast is needed in order to avoid the warning, which
      I'm not willing to insert at this time.
    - Added a typedef to bli_type_defs.h defining void_fp as void*, along
      with a commented-out version of the aborted definition described
      above. (Note that POSIX requires that void* and function pointers
      be interchangeable; it is the C standard that does not provide this
      guarantee.)
    - Comment updates to various _oapi.c files.

      results, this time using a development version cloned from their git
      mirror on March 27, 2019 (version 3.3.90). Performance is improved

    Added Eigen results to performance graphs.
    
    Details:
    - Updated the Haswell, SkylakeX, and Epyc performance graphs in
      docs/graphs to report on Eigen implementations, where applicable.
      Specifically, Eigen implements all level-3 operations sequentially,
      however, of those operations it only provides multithreaded gemm.
      Thus, mt results for symm/hemm, syrk/herk, trmm, and trsm are
      omitted. Thanks to Sameer Agarwal for his help configuring and
      using Eigen.
    - Updated docs/Performance.md to note the new implementation tested.
    - CREDITS file update.

      a new boolean function parameter, with_eigen.
    - Updated runme.m scratchpad to reflect the latest invocations of the
      plot_panel_4x5() function (with Eigen plotting enabled).

    - Fixed the Makefile in test/3 so that it no longer incorrectly labels
      the matlab output variables from Eigen-linked hemm, herk, trmm, and
      trsm driver output as "vendor". (The gemm drivers were already
      correctly outputing matlab variables containing the "eigen" label.)

    Test with shared on windows (#306)
    
    Export macros can't support both shared and static at the same time.
    When blis is built with both shared and static, headers assume that
    shared is used at link time and dllimports the symbols with __imp_
    prefix.
    
    To use the headers with static libraries a user can give
    -DBLIS_EXPORT= to import the symbol without the __imp_ prefix

    Link to Eigen BLAS for non-gemm drivers in test/3.
    
    Details:
    - Adjusted test/3/Makefile so that the test drivers are linked against
      Eigen's BLAS library for hemm, herk, trmm, and trsm. We have to do
      this since Eigen's headers don't define implementations to the
      standard BLAS APIs.
    - Simplified #included headers in hemm, herk, trmm, and trsm source
      driver files, since nothing specific to Eigen is needed at
      compile-time for those operations.

    Add more support for Eigen to drivers in test/3.
    
    Details:
    - Use compile-time implementations of Eigen in test_gemm.c via new
      EIGEN cpp macro, defined on command line. (Linking to Eigen's BLAS
      library is not necessary.) However, as of Eigen 3.3.7, Eigen only
      parallelizes the gemm operation and not hemm, herk, trmm, trsm, or
      any other level-3 operation.
    - Fixed a bug in trmm and trsm drivers whereby the wrong function
      (bli_does_trans()) was being called to determine whether the object
      for matrix A should be created for a left- or right-side case. This
      was corrected by changing the function to bli_is_left(), as is done
      in the hemm driver.
    - Added support for running Eigen test drivers from runme.sh.

    Allow disabling of BLAS prototypes at compile-time.
    
    Details:
    - Modified bli_blas.h so that:
      - By default, if the BLAS layer is enabled at configure-time, BLAS
        prototypes are also enabled within blis.h;
      - But if the user #defines BLIS_DISABLE_BLAS_DEFS prior to including
        blis.h, BLAS prototypes are skipped over entirely so that, for
        example, the application or some other header pulled in by the
        application may prototype the BLAS functions without causing any
        duplication.
    - Updated docs/BuildSystem.md to document the feature above, and
      related text.

    Usage: ./test_gemm_<mkl/blis/openblas>.x input.csv output.csv
    GEMM is called through BLAS interface
    For BLIS - the test application also prints either 'S' indicating small gemm routine or 'N' - conventional BLIS gemm

      variety of hardware architectures, comparing BLIS to OpenBLAS and a
      vendor library (MKL on Intel/AMD, ARMPL on ARM). Performance graphs,
      in pdf and png formats, reside in docs/graphs.
    - Updated README.md to link to new Performance.md document.
    - Minor updates to CREDITS, docs/Multithreading.md.
    - Minor updates to matlab scripts in test/3/matlab.

    Adjusted cache blocksizes for zen subconfig.
    
    Details:
    - Adjusted the zen sub-configuration's cache blocksizes for float,
      scomplex, and dcomplex based on the existing values for double.
      (The previous values were taken directly from the haswell subconfig,
      which targets Intel Haswell/Broadwell/Skylake systems.)

    Renamed --enable-export-all to --export-shared=[].
    
    Details:
    - Replaced the existing --enable-export-all / --disable-export-all
      configure option with --export-shared=[public|all], with the 'public'
      instance of the latter corresponding to --disable-export-all and the
      'all' instance corresponding to --enable-export-all. Nothing else
      semantically about the option, or its default, has changed.

    Updates to docs/Multithreading.md.
    
    Details:
    - Made extra explicit the fact that: (a) multithreading in BLIS is
      disabled by default; and (b) even with multithreading enabled, the
      user must specify multithreading at runtime in order to observe
      parallelism. Thanks to M. Zhou for suggesting these clarifications
      in #292.
    - Also made explicit that only the environment variable and global
      runtime API methods are available when using the BLAS API. If the
      user wishes to use the local runtime API (specify multithreading on
      a per-call basis), one of the native BLIS APIs must be used.

    Support shared lib export of only public symbols.
    
    Details:
    - Introduced a new configure option, --enable-export-all, which will
      cause all shared library symbols to be exported by default, or,
      alternatively, --disable-export-all, which will cause all symbols to
      be hidden by default, with only those symbols that are annotated for
      visibility, via BLIS_EXPORT_BLIS (and BLIS_EXPORT_BLAS for BLAS
      symbols), to be exported. The default for this configure option is
      --disable-export-all. Thanks to Isuru Fernando for consulting on
      this commit.
    - Removed BLIS_EXPORT_BLIS annotations from frame/1m/bli_l1m_unb_var1.h,
      which was intended for 5a5f494.
    - Relocated BLIS_EXPORT-related cpp logic from bli_config.h.in to
      frame/include/bli_config_macro_defs.h.
    - Provided appropriate logic within common.mk to implement variable
      symbol visibility for gcc, clang, and icc (to the extend that each of
      these compilers allow).
    - Relocated --help text associated with debug option (-d) to configure
      slightly further down in the list.

    Removed export macros from all internal prototypes.
    
    Details:
    - After merging PR #303, at Isuru's request, I removed the use of
      BLIS_EXPORT_BLIS from all function prototypes *except* those that we
      potentially wish to be exported in shared/dynamic libraries. In other
      words, I removed the use of BLIS_EXPORT_BLIS from all prototypes of
      functions that can be considered private or for internal use only.
      This is likely the last big modification along the path towards
      implementing the functionality spelled out in issue #248. Thanks
      again to Isuru Fernando for his initial efforts of sprinkling the
      export macros throughout BLIS, which made removing them where
      necessary relatively painless. Also, I'd like to thank Tony Kelman,
      Nathaniel Smith, Ian Henriksen, Marat Dukhan, and Matthew Brett for
      participating in the initial discussion in issue #37 that was later
      summarized and restated in issue #248.

    Renamed test/3m4m to test/3.
    
    Details:
    - Renamed '3m4m' directory to '3', which captures the directory nicely
      since it builds test drivers to test level-3 operations.
    - These test drivers ceased to be used to test the 3m and 4m (or even
      1m) induced methods long ago, hence the name change.

    Overhauled test/3m4m Makefile and scripts.
    
    Details:
    - Rewrote much of Makefile to generate executables for single- and dual-
      socket multithreading as well as single-threaded. Each of the three
      can also use a different problem size range/increment, as is often
      appropriate when doubling/halving the number of threads.
    - Rewrote runme.sh script to flexibly execute as many threading
      parameter scenarios as is given in the input parameter string
      (currently set within the script itself). The string also encodes
      the maximum problem size for each threading scenario, which is used
      to identify the executable to run. Also improved the "progress" output
      of the script to reduce redundant info and improve readability in
      terminals that are not especially wide.
    - Minor updates to test_*.c source files.
    - Updated matlab scripts according to changes made to the Makefile,
      test drivers, and runme.sh script, and renamed 'plot_all.m' to
      'runme.m'.

    Updated level-3 BLAS to call object API directly.
    
    Details:
    - Updated the BLAS compatibility layer for level-3 operations so that
      the corresponding BLIS object API is called directly rather than first
      calling the typed BLIS API. The previous code based on the typed BLIS
      API calls is still available in a deactivated cpp macro branch, which
      may be re-activated by #defining BLIS_BLAS3_CALLS_TAPI. (This does not
      yet correspond to a configure option. If it seems like people might
      want to toggle this behavior more regularly, a configure option can be
      added in the future.)
    - Updated the BLIS typed API to statically "pre-initialize" objects via
      new initializor macros. Initialization is then finished via calls to
      static functions bli_obj_init_finish_1x1() and bli_obj_init_finish(),
      which are similar to the previously-called functions,
      bli_obj_create_1x1_with_attached_buffer() and
      bli_obj_create_with_attached_buffer(), respectively. (The BLAS
      compatibility layer updates mentioned above employ this new technique
      as well.)
    - Transformed certain routines in bli_param_map.c--specifically, the
      ones that convert netlib-style parameters to BLIS equivalents--into
      static functions, now in bli_param_map.h. (The remaining three classes
      of conversation routines were left unchanged.)
    - Added the aforementioned pre-initializor macros to bli_type_defs.h.
    - Relocated bli_obj_init_const() and bli_obj_init_constdata() from
      bli_obj_macro_defs.h to bli_type_defs.h.
    - Added a few macros to bli_param_macro_defs.h for testing domains for
      real/complexness and precisions for single/double-ness.

      pasting function invocations into matlab to generate plots that are
      presently of interest to us.

      loop, and any parallelism specified to the ir loop will be redirected
      to the jr loop. (Note that because of inter-iteration dependencies,
      trsm cannot parallelize the ir loop. Parallelism via the pc loop is
      at least somewhat feasible in theory, but it would require tracking
      dependencies between blocks--something for which BLIS currently lacks
      the necessary supporting infrastructure.)

    Added support for IC loop parallelism to trsm.
    
    Details:
    - Parallelism within the IC loop (3rd loop around the microkernel) is
      now supported within the trsm operation. This is done via a new branch
      on each of the control and thread trees, which guide execution of a
      new trsm-only subproblem from within bli_trsm_blk_var1(). This trsm
      subproblem corresponds to the macrokernel computation on only the
      block of A that contains the diagonal (labeled as A11 in algorithms
      with FLAME-like partitioning), and the corresponding row panel of C.
      During the trsm subproblem, all threads within the JC communicator
      participate and parallelize along the JR loop, including any
      parallelism that was specified for the IC loop. (IR loop parallelism
      is not supported for trsm due to inter-iteration dependencies.) After
      this trsm subproblem is complete, a barrier synchronizes all
      participating threads and then they proceed to apply the prescribed
      BLIS_IC_NT (or equivalent) ways of parallelism (and any BLIS_JR_NT
      parallelism specified within) to the remaining gemm subproblem (the
      rank-k update that is performed using the newly updated row-panel of
      B). Thus, trsm now supports JC, IC, and JR loop parallelism.
    - Modified bli_trsm_l_cntl_create() to create the new "prenode" branch
      of the trsm_l cntl_t tree. The trsm_r tree was left unchanged, for
      now, since it is not currently used. (All trsm problems are cast in
      terms of left-side trsm.)
    - Updated bli_cntl_free_w_thrinfo() to be able to free the newly shaped
      trsm cntl_t trees. Fixed a potentially latent bug whereby a cntl_t
      subnode is only recursed upon if there existed a corresponding
      thrinfo_t node, which may not always exist (for problems too small
      to employ full parallelization due to the minimum granularity imposed
      by micropanels).
    - Updated other functions in frame/base/bli_cntl.c, such as
      bli_cntl_copy() and bli_cntl_mark_family(), to recurse on sub-prenodes
      if they exist.
    - Updated bli_thrinfo_free() to recurse into sub-nodes and prenodes
      when they exist, and added support for growing a prenode branch to
      bli_thrinfo_grow() via a corresponding set of help functions named
      with the _prenode() suffix.
    - Added a bszid_t field thrinfo_t nodes. This field comes in handy when
      debugging the allocation/release of thrinfo_t nodes, as it helps trace
      the "identity" of each nodes as it is created/destroyed.
    - Renamed
        bli_l3_thrinfo_print_paths() -> bli_l3_thrinfo_print_gemm_paths()
      and created a separate bli_l3_thrinfo_print_trsm_paths() function to
      print out the newly reconfigured thrinfo_t trees for the trsm
      operation.
    - Trival changes to bli_gemm_blk_var?.c and bli_trsm_blk_var?.c
      regarding variable declarations.
    - Removed subpart_t enum values BLIS_SUBPART1T, BLIS_SUBPART1B,
      BLIS_SUBPART1L, BLIS_SUBPART1R. Then added support for two new labels
      (semantically speaking): BLIS_SUBPART1A and BLIS_SUBPART1B, which
      represent the subpartition ahead of and behind, respectively,
      BLIS_SUBPART1. Updated check functions in bli_check.c accordingly.
    - Shuffled layering/APIs for bli_acquire_mpart_[mn]dim() and
      bli_acquire_mpart_t2b/b2t(), _l2r/r2l().
    - Deprecated old functions in frame/3/bli_l3_thrinfo.c.

    Power9 sub-configuration  (#298)
    
    Formally registered power9 sub-configuration.
    
    Details:
    - Added and registered power9 sub-configuration into the build system.
      Thanks to Nicholai Tukanov and Devangi Parikh for these contributions.
    - Note: The sub-configuration does not yet have a corresponding
      architecture-specific kernel set registered, and so for now the
      sub-config is using the generic kernel set.

    Generalized ref kernels' pragma omp simd usage.
    
    Details:
    - Replaced direct usage of _Pragma( "omp simd" ) in reference kernels
      with PRAGMA_SIMD, which is defined as a function of the compiler being
      used in a new bli_pragma_macro_defs.h file. That definition is cleared
      when BLIS detects that the -fopenmp-simd command line option is
      unsupported. Thanks to Devin Matthews and Jeff Hammond for suggestions
      that guided this commit.
    - Updated configure and bli_config.h.in so that the appropriate anchor
      is substituted in (when the corresponding pragma omp simd support is
      present).

    Minor updates to docs, Makefiles.
    
    Details:
    - Changed all occurrances of
        micro-kernel -> microkernel
        macro-kernel -> macrokernel
        micro-panel  -> micropanel
      in all markdown documents in 'docs' directory. This change is being
      made since we've reached the point in adoption and acceptance of
      BLIS's insights where words such as "microkernel" are no longer new,
      and therefore now merit being unhyphenated.
    - Updated "Implementation Notes" sections of KernelsHowTo.md, which
      still contained references to nonexistent cpp macros such as
      BLIS_DEFAULT_MR_? and BLIS_PACKDIM_MR_?.
    - Added 'run-fast' and 'check-fast' targets to testsuite/Makefile.
    - Minor updates to Testsuite.md, including suggesting use of
      'make check' and 'make check-fast' when running from the local
      testsuite directory.
    - Added a comment to top-level Makefile explaining the purpose behind
      the TESTSUITE_WRAPPER variable, which at first glance appears to serve
      no purpose.

    Fixed bug in skx subconfig related to bdd46f9.
    
    Details:
    - Fixed code in the skx subconfiguration that became a bug after
      committing bdd46f9. Specifically, the bli_cntx_init_skx() function
      was overwriting default blocksizes for the scomplex and dcomplex
      microkernels despite the fact that only single and double real
      microkernels were being registered. This was not a problem prior to
      bdd46f9 since all microkernels used dynamically-queried (at runtime)
      register blocksizes for loop bounds. However, post-bdd46f9, this
      became a bug because the reference ukernels for scomplex and dcomplex
      were written with their register blocksizes hard-coded as constant
      loop bounds, which conflicted the the erroneous scomplex and dcomplex
      values that bli_cntx_init_skx() was setting in the context. The
      lesson here is that going forward, all subconfigurations must not set
      any blocksizes for datatypes corresponding to default/reference
      microkernels. (Note that a blocksize is left unchanged by the
      bli_cntx_set_blkszs() function if it was set to -1.)

    Fixed undefined behavior trsm ukr bug in bdd46f9.
    
    Details:
    - Fixed a bug that mainfested anytime a configuration was used in which
      optimized microkernels were registered and the trsm operation (or
      kernel) was invoked. The bug resulted from the optimized microkernels'
      register blocksizes conflicting with the hard-coded values--expressed
      in the form of constant loop bounds--used in the new reference trsm
      ukernels that were introduced in bdd46f9. The fix was easy: reverting
      back to the implementation that uses variable-bound loops, which
      amounted to changing an #if 0 to #if 1 (since I preserved the older
      implementation in the file alongside the new code based on constant-
      bound loops). It should be noted that this fix must be permanent,
      since the trsm kernel code with constant-bound loops can never work
      with gemm ukernels that use different register blocksizes.

    Rewrote reference kernels to use #pragma omp simd.
    
    Details:
    - Rewrote level-1v, -1f, and -3 reference kernels in terms of simplified
      indexing annotated by the #pragma omp simd directive, which a compiler
      can use to vectorize certain constant-bounded loops. (The new kernels
      actually use _Pragma("omp simd") since the kernels are defined via
      templatizing macros.) Modest speedup was observed in most cases using
      gcc 5.4.0, which may improve with newer versions. Thanks to Devin
      Matthews for suggesting this via issue #286 and #259.
    - Updated default blocksizes defined in ref_kernels/bli_cntx_ref.c to
      be 4x16, 4x8, 4x8, and 4x4 for single, double, scomplex and dcomplex,
      respectively, with a default row preference for the gemm ukernel. Also
      updated axpyf, dotxf, and dotxaxpyf fusing factors to 8, 6, and 4,
      respectively, for all datatypes.
    - Modified configure to verify that -fopenmp-simd is a valid compiler
      option (via a new detect/omp_simd/omp_simd_detect.c file).
    - Added a new header in which prefetch macros are defined according to
      which compiler is detected (via macros such as __GNUC__). These
      prefetch macros are not yet employed anywhere, though.
    - Updated the year in copyrights of template license headers in
      build/templates and removed AMD as a default copyright holder.

    Minor tweaks/cleanups to bli_malloc.c, _apool.c.
    
    Details:
    - Removed malloc_ft and free_ft function pointer arguments from the
      interface to bli_apool_init() after deciding that there is no need to
      specify the malloc()/free() for blocks within the apool. (The apool
      blocks are actually just array_t structs.) Instead, we simply call
      bli_malloc_intl()/_free_intl() directly. This has the added benefit
      of allowing additional output when memory tracing is enabled via
      --enable-mem-tracing. Also made corresponding changes elsewhere in
      the apool API.
    - Changed the inner pools (elements of the array_t within the apool_t)
      to use BLIS_MALLOC_POOL and BLIS_FREE_POOL instead of BLIS_MALLOC_INTL
      and BLIS_FREE_INTL.
    - Disabled definitions of bli_malloc_pool() and bli_free_pool() since
      there are no longer any consumers of these functions.
    - Very minor comment / printf() updates.

    Allow running configure with python 3.4.
    
    Details:
    - Relax version blacklisting of python3 to allow 3.4 or later instead
      of 3.5 or later. Thanks to Dave Love for pointing out that 3.4 was
      sufficient for the purpose of BLIS's build system. (It should be
      noted that we're not sure which, if any, python3 versions prior to
      3.4 are insufficient, and that the only thing stopping us from
      determining this is the fact that these earlier versions of python3
      are not readily available for us to test with.)
    - Updated docs/BuildSystem.md to be explicit about current python2 vs
      python3 version requirements.

    Add error message to malloc() check for NULL.
    
    Details:
    - Output an error message if and when the malloc()-equivalent called by
      bli_fmalloc_align() ever returns NULL. Everything was already in place
      for this to happen, including the error return code, the error string
      sprintf(), the error checking function bli_check_valid_malloc_buf()
      definition, and its prototype. Thanks to Minh Quan Ho for pointing out
      the missing error message.
    - Increased the default block_ptrs_len for each inner pool stored in the
      small block allocator from 10 to 25. Under normal execution, each
      thread uses only 21 blocks, so this change will prevent the sba from
      needing to resize the block_ptrs array of any given inner pool as
      threads initially populate the pool with small blocks upon first
      execution of a level-3 operation.
    - Nix stray newline echo in configure.

    Implemented a pool-based small block allocator.
    
    Details:
    - Implemented a sophisticated data structure and set of APIs that track
      the small blocks of memory (around 80-100 bytes each) used when
      creating nodes for control and thread trees (cntl_t and thrinfo_t) as
      well as thread communicators (thrcomm_t). The purpose of the small
      block allocator, or sba, is to allow the library to transition into a
      runtime state in which it does not perform any calls to malloc() or
      free() during normal execution of level-3 operations, regardless of
      the threading environment (potentially multiple application threads
      as well as multiple BLIS threads). The functionality relies on a new
      data structure, apool_t, which is (roughly speaking) a pool of
      arrays, where each array element is a pool of small blocks. The outer
      pool, which is protected by a mutex, provides separate arrays for each
      application thread while the arrays each handle multiple BLIS threads
      for any given application thread. The design minimizes the potential
      for lock contention, as only concurrent application threads would
      need to fight for the apool_t lock, and only if they happen to begin
      their level-3 operations at precisely the same time. Thanks to Kiran
      Varaganti and AMD for requesting this feature.
    - Added a configure option to disable the sba pools, which are enabled
      by default; renamed the --[dis|en]able-packbuf-pools option to
      --[dis|en]able-pba-pools; and rewrote the --help text associated with
      this new option and consolidated it with the --help text for the
      option associated with the sba (--[dis|en]able-sba-pools).
    - Moved the membrk field from the cntx_t to the rntm_t. We now pass in
      a rntm_t* to the bli_membrk_acquire() and _release() APIs, just as we
      do for bli_sba_acquire() and _release().
    - Replaced all calls to bli_malloc_intl() and bli_free_intl() that are
      used for small blocks with calls to bli_sba_acquire(), which takes a
      rntm (in addition to the bytes requested), and bli_sba_release().
      These latter two functions reduce to the former two when the sba pools
      are disabled at configure-time.
    - Added rntm_t* arguments to various cntl_t and thrinfo_t functions, as
      required by the new usage of bli_sba_acquire() and _release().
    - Moved the freeing of "old" blocks (those allocated prior to a change
      in the block_size) from bli_membrk_acquire_m() to the implementation
      of the pool_t checkout function.
    - Miscellaneous improvements to the pool_t API.
    - Added a block_size field to the pblk_t.
    - Harmonized the way that the trsm_ukr testsuite module performs packing
      relative to that of gemmtrsm_ukr, in part to avoid the need to create
      a packm control tree node, which now requires a rntm_t that has been
      initialized with an sba and membrk.
    - Re-enable explicit call bli_finalize() in testsuite so that users who
      run the testsuite with memory tracing enabled can check for memory
      leaks.
    - Manually imported the compact/minor changes from 61441b24 that cause
      the rntm to be copied locally when it is passed in via one of the
      expert APIs.
    - Reordered parameters to various bli_thrcomm_*() functions so that the
      thrcomm_t* to the comm being modified is last, not first.
    - Added more descriptive tracing for allocating/freeing small blocks and
      formalized via a new configure option: --[dis|en]able-mem-tracing.
    - Moved some unused scalm code and headers into frame/1m/other.
    - Whitespace changes to bli_pthread.c.
    - Regenerated build/libblis-symbols.def.

    Make local copy of user's rntm_t in level-3 ops.
    
    Details:
    - In the case that the caller passes in a non-NULL rntm_t pointer into
      one of the expert APIs for a level-3 operation (e.g. bli_gemm_ex()),
      make a local copy of the rntm_t and use the address of that local copy
      in all subsequent execution (which may change the contents of the
      rntm_t). This prevents a potentially confusing situation whereby a
      user-initialized rntm_t is used once (in, say, gemm), and then found
      by the user to be in a different state before it is used a second
      time.

    Fixed BLAS test failures of small matrix SYRK for single and double precision.
    
    Details:
    - SYRK for small matrix was implemented by reusing small GEMM routine. This was
      resulting in output written to the full C matrix, and C being symmetric the
      lower and upper triangles of C matrix contained same results. BLAS SYRK API
      spec demands either lower or upper triangle of C matrix to be written with
      results. So, this was resulting in BLAS test failures, even though testsuite
      of BLIS was passing small SYRK operation.
    - To fix BLAS test failures of small matrix SYRK, separate kernel routines are
      implemented for small SYRK for both single and double precision. The newly
      added small SYRK routines are in file kernels/zen/3/bli_syrk_small.c.
      Now the intermediate results of matrix C are written to a scratch buffer.
      Final results are written from scratch buffer to matrix C using SIMD
      copy to either lower or upper traingle part of matrix C.
    - Source and header files frame/3/syrk/bli_syrk_front.c and
      frame/3/syrk/bli_syrk_front.h are changed to invoke new small SYRK routines.

    Added missing bli_init_once() in bli_thread API.
    
    Details:
    - Fixed an issue with specifying threading globally at runtime via
      bli_thread_set_num_threads() (the automatic way) or via
      bli_thread_set_ways() (the manual way), with bli_thread_init_rntm()
      also affected. These functions were not calling bli_init_once() prior
      to acting, and therefore their effects on the global rntm_t structure
      were being wiped out by the eventual call to bli_init_once(), by some
      other BLIS function. Thanks to Ali Emre Gülcü for reporting the
      behavior associated with this bug.
    - Added additional content to docs/Multithreading.md covering topics of
      choosing between OpenMP and pthreads, and specifying affinity via
      OpenMP.

    Improvements to bli_pool; malloc()/free() tracing.
    
    Details:
    - Added malloc_ft and free_ft fields to pool_t, which are provided when
      the pool is initialized, to allow bli_pool_alloc_block() and
      bli_pool_free_block() to call bli_fmalloc_align()/bli_ffree_align()
      with arbitrary align_size values (according to how the pool_t was
      initialized).
    - Added a block_ptrs_len argument to bli_pool_init(), which allows the
      caller to specify an initial length for the block_ptrs array, which
      previously suffered the cost of being reallocated, copied, and freed
      each time a new block was added to the pool.
    - Consolidated the "buf_sys" and "buf_align" pointer fields in pblk_t
      into a single "buf" field. Consolidated the bli_pblk API accordingly
      and also updated the bli_mem API implementation. This was done
      because I'd previously already implemented opaque alignment via
      bli_malloc_align(), which allocates extra space and stores the
      original pointer returned by malloc() one element before the element
      whose address is aligned.
    - Tweaked bli_membrk_acquire_m() and bli_membrk_release() to call
      bli_fmalloc_align() and bli_ffree_align(), which required adding an
      align_size field to the membrk_t struct.
    - Pass the pack schemas directly into bli_l3_cntl_create_if() rather
      than transmit them via objects for A and B.
    - Simplified bli_l3_cntl_free_if() and renamed to bli_l3_cntl_free().
      The function had not been conditionally freeing control trees for
      quite some time. Also, removed obj_t* parameters since they aren't
      needed anymore (or never were).
    - Spun-off OpenMP nesting code in bli_l3_thread_decorator() to a
      separate function, bli_l3_thread_decorator_thread_check().
    - Renamed:
        bli_malloc_align()   -> bli_fmalloc_align()
        bli_free_align()     -> bli_ffree_align()
        bli_malloc_noalign() -> bli_fmalloc_noalign()
        bli_free_noalign()   -> bli_ffree_noalign()
      The 'f' is for "function" since they each take a malloc_ft or free_ft
      function pointer argument.
    - Inserted various printf() calls for the purposes of tracing memory
      allocation and freeing, guarded by cpp macro ENABLE_MEM_DEBUG, which,
      for now, is intended to be a "hidden" feature rather than one hooked
      up to a configure-time option.
    - Defined bli_rntm_equals(), which compares two rntm_t for equality.
      (There are no use cases for this function yet, but there may be soon.)
    - Whitespace changes to function parameter lists in bli_pool.c, .h.

    Handle edge cases, zero-filling in packm kernels.
    
    Details:
    - Updated the API and semantics of packm kernels such that they must now
      handle edge cases, meaning that a c-by-k packm kernel must be able to
      pack edge cases that are fewer than c rows/columns and be able to
      zero-fill the remaining elements. They must also be able to zero-fill
      the equivalent region when copying fewer than k columns/rows (which is
      needed by trsm). The new packm kernel API is generally:
    
        void packm_kernel
             (
               conj_t           conja,
               dim_t            cdim,
               dim_t            n,
               dim_t            n_max,
               ctype*  restrict kappa,
               ctype*  restrict a, inc_t inca, inc_t lda,
               ctype*  restrict p,             inc_t ldp,
               cntx_t* restrict cntx
             );
    
      where cdim and n are the dimensions (short and long, respectively) of
      the submatrix being copied from the source matrix A, and n_max is the
      "full" long dimension (corresponding to the k dimension in gemm) of
      the micropanel. The "full" short dimension (corresponding to the
      register blocksize MR or NR) is not part of the API because it is
      known intrinsically by the packm kernel implementation. Thanks to
      Devin Matthews for prompting us to make this change (#282).
    - Updated all reference packm kernels in ref_kernels/1m according to
      above changes, as well as all optimized packm kernels (which only
      consisted of those for knl).
    - Bumped the major soname version number in 'so_version' to 2. At first
      I was considering leaving it unchanged, but I couldn't escape the
      reality that the packm kernel API is much closer to an expert API
      than it is some obscure helper function interface within the framework
      that nobody would ever notice.
    - Removed reference packm kernels for mr/nr = 30. The only sub-config
      that would have been using those kernels is knc, which is likely no
      longer being used by very many people (if any). (This also mostly
      offset the larger object code footprint incurred by moving the edge-
      case handling into the individual packm kernels.)
    - Fixed an obscure race condition for 3mh and 4mh induced methods in
      which those implementations were modifying the contexts stored in the
      gks rather than a local copy.
    - Fixed a minor bug in the testsuite that prevented non-1m-based induced
      method implementations of trsm from executing.

    Disabled ARM configuration families in registry.
    
    Details:
    - Disabled (commented out) the arm32 and arm64 configuration families
      in the config_registry file. Having a configuration family registered
      only makes sense if BLIS is currently outfitted with runtime hardware
      detection logic to choose the appropriate sub-configuration. That
      logic is currently missing for ARM architectures, and thus having the
      ARM configuration families in the configuration registry only serves
      to confuse people. Thanks to Devangi Parikh for suggesting this
      change.

      test whatever method is enabled automatically for complex datatypes.

    Added mixed-precision support to 1m method.
    
    Details:
    - Lifted the constraint that 1m only be used when all operands' storage
      datatypes (along with the computation datatype) are equal. Now, 1m may
      be used as long as all operands are stored in the complex domain. This
      change largely consisted of adding the ability to pack to 1e and 1r
      formats from one precision to another. It also required adding logic
      for handling complex values of alpha to bli_packm_blk_var1_md()
      (similar to the logic in bli_packm_blk_var1()).
    - Fixed a bug in several virtual microkernels (bli_gemm_md_c2r_ref.c,
      bli_gemm1m_ref.c, and bli_gemmtrsm1m_ref.c) that resulted in the wrong
      ukernel output preference field being read. Previously, the preference
      for the native complex ukernel was being read instead of the pref for
      the native real domain ukernel. This bug would not manifest if the
      preference for the native complex ukernel happened to be equal to that
      of the native real ukernel.
    - Added support for testing mixed-precision 1m execution via the gemm
      module of the testsuite.
    - Tweaked/simplified bli_gemm_front() and bli_gemm_md.c so that pack
      schemas are always read from the context, rather than trying to
      sometimes embed them directly to the A and B objects. (They are still
      embedded, but now uniformly only after reading the schemas from the
      context.)
    - Redefined cpp macro bli_l3_ind_recast_1m_params() as a static function
      and renamed to bli_gemm_ind_recast_1m_params() (since gemm is the only
      consumer).
    - Added 1m optimization logic (via bli_gemm_ind_recast_1m_params()) to
      bli_gemm_ker_var2_md().
    - Added explicit handling for beta == 1 and beta == 0 in the reference
      gemm1m virtual microkernel in ref_kernels/ind/bli_gemm1m_ref.c.
    - Rewrote various level-0 macro defs, including axpyris, axpbyris,
      scal2ris, and xpbyris (and their conjugating counterparts) to
      explicitly support three operand types and updated invocations to
      xpbyris in bli_gemmtrsm1m_ref.c.
    - Query and use the storage datatype of the packed object instead of the
      storage datatype of the source object in bli_packm_blk_var1().
    - Relocated and renamed frame/ind/misc/bli_l3_ind_opt.h to
      frame/3/gemm/ind/bli_gemm_ind_opt.h.
    - Various whitespace/comment updates.

    Track internal scalar datatypes.
    
    Details:
    - Added a num_t datatype bitfield to the obj_t in the form of a new
      info2 field in the obj_t. This change was made primarily so that in
      the case of mixed-datatype gemm, the alpha scalar would not need to
      be cast to the storage datatype of B (or A) before then being cast to
      the computation datatype just before the macrokernel is called. This
      double-casting regime could result in loss of precision if the storage
      datatype of B (or A) is less than the computation precision. In
      practice, it was likely not going to be a big deal since most usage of
      alpha is for -1.0, 0.0, and 1.0 (or integer multiples thereof), which
      can all be represented exactly in single or double precision.
    - The type of objbits_t was changed to uint32_t, so the new format
      potentially takes up the same space as the previous obj_t definition,
      assuming no padding inserted by the compiler. Shrinking info to 32
      bits and spilling over into a second field was chosen over using the
      high 32 bits of a single 64-bit objbits_t info field because many of
      the bitwise operations are performed with enums such as num_t, dom_t,
      and prec_t, which may take on the type of 32-bit ints. It's easier to
      just keep all of those bitwise operations in 32 bits than perform a
      million typecasts throughout bli_type_defs.h and bli_obj_macro_defs.h
      to ensure that the integers are treated as 64-bit for the purposes of
      the ANDs, ORs, and bitshifts.
    - Many comment updates.
    - Thanks to Devin Matthews and Devangi Parikh for their feedback and
      involvement during this commit cycle.

    Tweak testsuite to issue FAIL for Nan, Inf (#279).
    
    Details:
    - Adjusted the definition for libblis_test_get_string_for_result() in
      testsuite/src/test_libblis.c so that the "FAIL" string is returned if
      the computed residual contains either NaN or Inf. Previously, a
      residual containing NaN would result in the selection of the "PASS"
      string. Thanks to Devin Matthews for reporting this issue (#279).
    - Expounded on comment for the macro definitions of bli_isnan() and
      bli_isinf() in bli_misc_macro_defs.h to make it more obvious why they
      must remain macros.

    Added 4x5 matlab plotting scripts to test/3m4m.
    
    Details:
    - Added a new directory, test/3m4m/matlab, containing matlab scripts for
      plotting 4x5 panels of performance graphs (using the subplot()
      function) for gemm, hemm, herk, trmm, and trsm across all four
      floating-point datatypes. I expect to further refine these scripts as
      time goes on, but their current state constitutes a good start.

    Fixed a bug in high-level mixeddt conditional.
    
    Details:
    - Fixed a bug in frame/3/bli_l3_oapi.c in the conditional that divides
      use of induced method (1m) execution from native execution. The former
      was intended to only be used in cases where all storage datatypes are
      complex and the datatype of C is equal to the computation datatype.
      (If mixed datatypes are detected, native execution would be used.)
      However, the code in bli_gemm() was erroneously checking the execution
      datatype instead of the computation datatype, which at that point is
      guaranteed to be equal to the storage datatype even if the computation
      datatype contains a different value. Thanks to Devangi Parikh for
      helping in isolating this bug.

    - Added plot_dt_select.m in order to plot select graphs for the main
      body of the mixeddt paper, and added additional related legend
      handling in plot_gemm_perf.m.
    - Added test/mixeddt/matlab/output and a .gitkeep file within in order

      data for mixeddt paper, including renaming implementations to
      "internal" and "ad-hoc" to match the terminology to be used in the
      paper.
    - Added new matlab scripts for generating 8 figures, each covering all
      mixed-precision cases for each mixed-domain case.
    - Updated the runme.sh script according to changes to Makefile.
    - Fixed a minor bug in test_gemm.c that may have given incorrect
      performance in complex, homogeneous storage datatype cases where
      the computation precision was equal to the storage precisions.

    Testsuite docs update for mixed-datatype gemm.
    
    Details:
    - Updated docs/Testsuite.md to include mention of the new mixed-domain
      and mixed-precision settings, including descriptions.
    - Updated docs/MixedDatatypes.md to include a brief section on running
      the testsuite to exercise mixed-datatype functionality, which mostly
      amounts to a link to the Testsuite.md document.
    - Minor verbiage change to testsuite output to correct a misleading
      label associated with the value returned by the query function
      bli_info_get_simd_num_registers(). (The function does not return the
      number of SIMD registers present in the hardware, but rather a maximum
      assumed value for the purposes of allocating temporary microtile
      workspace on the function stack.)

    Disallow 64b BLAS integers + 32b BLIS integers.
    
    Details:
    - Print an error message from configure if the user attempts to
      explicitly configure BLIS for simultaneous use of 64-bit integers in
      the BLAS API with 32-bit integers in the BLIS API.
    - Added cpp macro conditional to bli_type_defs.h to mandate that BLIS
      integers be 64 bits if the BLAS integers are 64 bits. This and the
      above item take care of issue #274. Thanks to Devin Matthews and
      Jeff Hammond for suggesting these safeguards.
    - Slight reorganization and relabeling (for clarity) of BLAS/CBLAS
      sections and BLIS integer size line of the testsuite configuration
      output.
    - Very minor edits to docs/MixedDatatypes.md.

      travis/do_testsuite.sh.
    - Added a new pair of input files to testsuite directory with the
      '.salt' suffix (similar to those with the '.fast' suffix) for
      testing application-level threading.
    - Updated docs/BuildSystem.md to document the new make targets
      'testblis-salt' and 'checkblis-salt'.

    Add bli_pthread_mutex_trylock().
    
    Details:
    - Added the missing bli_pthread_mutex_trylock() function and prototype
      to the non-Windows sections of bli_pthread.c and .h. This function
      isn't needed by BLIS, but I figured why not make the Windows and
      non-Windows sections consistent with one another.

    Defined unified bli_pthreads_*() API for all OSes.
    
    Details:
    - Expanded the bli_pthread_*() -> pthread_*() wrappers in
      frame/thread/bli_pthread.c to include cases for Windows taken from
      frame/base/bli_pthread_wrap.c. Now, bli_thread_*() is always defined
      and always used by BLIS and the BLIS testsuite (in lieu of calling
      pthreads directly, as before). The implementation used in this new
      API depends on whether we are building for Windows, and to a lesser
      extent, whether we are building on OS X. For the core API, Windows
      uses Windows threads, non-Windows (Linux, OS X) uses pthreads.
      OS X and Windows get barriers implemented in terms of other
      bli_pthread_*() functions, and Linux gets barriers implemented in
      terms of pthread_barrier*(). This commit addresses issue #273.
    - Fixed a bug in the Linux definition of bli_pthread_mutex_unlock(),
      which was erroneously calling pthread_mutex_lock().
    - Minor changes to configure so that the auto-detection executable
      can be built given the above changes (most notably, turning on
      POSIX extensions via -D_GNU_SOURCE).
    - Removed temporary play-test code for shiftd that accidentally got
      committed into test/3m4m/test_gemm.c.

    Unconditionally define bli_l3_thread_entry().
    
    Details:
    - Define a dummy bli_l3_thread_entry() function when multithreading is
      disabled altogether, or enabled via OpenMP. This function was
      originally necessary when multithreading is enabled via pthreads.
      By defining the function no matter the threading options given, it is
      less likely that an AppVeyor Windows build will complain due to a
      missing symbol in the DLL. (To be clear: AppVeyor was working fine
      before, but a problem may have arisen if it were switched to an
      OpenMP build.)
    - Removed the prototype for bli_l3_thread_entry() from
      bli_thrcomm_pthreads.c and placed it in bli_thrcomm.h.
    - Regenerated the symbols list file build/libblis-symbols.def.

      mixed-datatype gemm.
    - Updated docs/BuildSystem.md to document the new make targets

    Fixed thrinfo_t printing for small problems.
    
    Details:
    - Fixed a bug in the code that prints out the communicator and work ids
      from the various threads' thrinfo_t nodes. This bug manifested when
      the dimension being parallelized was not large enough such that every
      thread was assigned actual work (since the minimum amount of work is
      determined by the register blocksize in the dimension being
      parallelized). In those cases, the threads that receive no work in
      that dimension do not finish building their thrinfo_t tree, leaving
      lower-level nodes non-existent. (The bug itself was usally observed as
      a segfault when the printing code attempted to dereference all the way
      down the thrinfo_t tree.) The solution involves explicitly checking
      each node as it is dereferenced, and if at any time NULL is found, all
      subsequent communicator and work ids are set to -1.

    Implemented python version checking in configure.
    
    Details:
    - Added python version checking to configure script. (Recall that python
      is needed to execute the flatten-headers.py script.) Minimum versions
      of python needed are currently as follows:
        python2: 2.7 or later
        python3: 3.5 or later
      The standard search order for python interpeters is:
        python python3 python2
      The PYTHON environment variable is also supported and will be checked
      before the standard search order list.
    - Updated BuildSystem.md to include: a minimum make version; mention
      that the C compiler must actually be a C99 compiler; and the caveat
      that Windows builds do not require pthreads since BLIS can provide
      an implementation of pthreads internally.

    Added bli_pthread_*() API.
    
    Details:
    - Defined a bli_pthread_*() API so that the testsuite, when being linked
      against a Windows DLL, will be able to access pthreads functionality
      without those pthreads functions being explicitly exported by the DLL.
      Instead, we export the bli_pthread_*() layer, which uses types and
      functions that are identical to pthreads, but adds a 'bli_' prefix.
      Only a few basic functions are present in the bli_pthreads_*() API
      for now. Thanks to Devin Matthews and Isuru Fernando for their help
      on a related PR (#261) that this commit will hopefully facilitate.
    - Updated testsuite so that it calls bli_pthread_*() layer instead of
      pthread_*() functions directly.
    - Regenerated build/libblis-symbols.def.
    - Comment updated to build/regen-symbols.sh.

    Defined a new level-1d operation: shiftd.
    
    Details:
    - Defined a new level-1d operation called 'shiftd', including object and
      typed APIs. This operation adds a scalar value to every element along
      an arbitrary diagonal of a matrix. Currently, shiftd is implemented in
      terms of the addv kernel. (The scalar is passed in as the x vector
      with an increment of zero.)
    - Replaced ad-hoc usage of setd and addd (after creating a temporary
      matrix object) with use of shiftd, which is much more concise, in
      various test driver files in the testsuite. Similar changes were made
      to the standalone test drivers and the example code.
    - Added documentation entries in BLISObjectAPI.md and BLISTypedAPI.md
      for bli_shiftd() and bli_?shiftd(), respectively.
    - Added observed object properties to level-1d documentation in
      BLISObjectAPI.md.

    Renamed/moved l3 zen ukernels to haswell kernel set.
    
    Details:
    - Renamed the microkernels in kernels/zen/3 to kernels/haswell/3 and
      then updated the file contents to use the 'haswell' infix.
    - Updated bli_cntx_init_zen.c and bli_cntx_init_haswell.c according to
      above function renames.
    - Moved/updated the corresponding prototypes in bli_kernels_zen.h to
      bli_kernels_haswell.h.
    - Updated config_registry according to above changes.
    - NOTE: This rename reflects the fact that haswell microkernels are
      specifically written to overcome the floating-point latency for FMA
      instructions on Intel Haswell-like architectures, which can issue two
      FMA instructions per cycle. These ukernels happen to work fine on AMD
      Zen-based architectures. However, Zen only issues one FMA per cycle,
      which, while halving its floating-point throughput, gives it extra
      flexibility in the design of its microkernels--namely, mr and nr can
      be smaller and still overcome the floating-point latency for those
      single-issue cores. A smaller value of mr and nr allows for a larger
      value of kc, which may be useful in some situations. In the future,
      we may write such Zen-specific microkernels to take advantage of this
      additional flexibility.

    Consolidated slab/rr-explicit level-3 macrokernels.
    
    Details:
    - Consolidated the *sl.c and *rr.c level-3 macrokernels into a single
      file per sl/rr pair, with those files named as they were before
      c92762e. The consolidation does not take away the *option* of using
      slab or round-robin assignment of micropanels to threads; it merely
      *hides* the choice within the definitions of functions such as
      bli_thread_range_jrir(), bli_packm_my_iter(), and bli_is_last_iter()
      rather than expose that choice explicitly in the code. The choice of
      slab or rr is not always hidden, however; there are some cases
      involving herk and trmm, for example, that require some part of the
      computation to use rr unconditionally. (The --thread-part-jrir option
      controls the partitioning in all other cases.)
    - Note: Originally, the sl and rr macrokernels were separated out for
      clarity. However, aside from the additional binary code bloat, I later
      deemed that clarity not worth the price of maintaining the additional
      (mostly similar) codes.

    Implemented mixed-datatype support for gemm.
    
    Details:
    - Implemented support for gemm where A, B, and C may have different
      storage datatypes, as well as a computational precision (and implied
      computation domain) that may be different from the storage precision
      of either A or B. This results in 128 different combinations, all
      which are implemented within this commit. (For now, the mixed-datatype
      functionality is only supported via the object API.) If desired, the
      mixed-datatype support may be disabled at configure-time.
    - Added a memory-intensive optimization to certain mixed-datatype cases
      that requires a single m-by-n matrix be allocated (temporarily) per
      call to gemm. This optimization aims to avoid the overhead involved in
      repeatedly updating C with general stride, or updating C after a
      typecast from the computation precision. This memory optimization may
      be disabled at configure-time (provided that the mixed-datatype
      support is enabled in the first place).
    - Added support for testing mixed-datatype combinations to testsuite.
      The user may test gemm with mixed domains, precisions, both, or
      neither.
    - Added a standalone test driver directory for building and running
      mixed-datatype performance experiments.
    - Defined a new variation of castm, castnzm, which operates like castm
      except that imaginary values are not touched when casting a real
      operand to a complex operand. (By contrast, in these situations castm
      sets the imaginary components of the destination matrix to zero.)
    - Defined bli_obj_imag_is_zero() and substituted calls in lieu of all
      usages of bli_obj_imag_equals() that tested against BLIS_ZERO, and
      also simplified the implementation of bli_obj_imag_equals().
    - Fixed bad behavior from bli_obj_is_real() and bli_obj_is_complex()
      when given BLIS_CONSTANT objects.
    - Disabled dt_on_output field in auxinfo_t structure as well as all
      accessor functions. Also commented out all usage of accessor
      functions within macrokernels. (Typecasting in the microkernel is
      still feasible, though probably unrealistic for now given the
      additional complexity required.)
    - Use void function pointer type (instead of void*) for storing function
      pointers in bli_l0_fpa.c.
    - Added documentation for using gemm with mixed datatypes in
      docs/MixedDatatypes.md and example code in examples/oapi/11gemm_md.c.
    - Defined level-1d operation xpbyd and level-1m operation xpbym.
    - Added xpbym test module to testsuite.
    - Updated frame/include/bli_x86_asm_macros.h with additional macros
      (courtsey of Devin Matthews).

      suggesting these new interfaces.
    - Added missing prototype for bli_thread_set_ways() in bli_thread.h and
      removed prototypes for non-existent functions bli_thread_set_*_nt().
    - CREDITS file update.

    Renamed thread auto-factorization macro constants.
    
    Details:
    - Renamed the following C preprocessor macros whose fallback/default
      values are specified within frame/include/bli_kernel_macro_defs.h:
    
        BLIS_DEFAULT_MR_THREAD_MAX  -> BLIS_THREAD_MAX_IR
        BLIS_DEFAULT_NR_THREAD_MAX  -> BLIS_THREAD_MAX_JR

        BLIS_DEFAULT_N_THREAD_RATIO -> BLIS_THREAD_RATIO_N
    
    - Renamed the above cpp macro overrides within the knl, skx, and zen
      sub-configurations, as well as invocations of those macros in
      bli_rntm.c.
    - Moved config/zen/bli_kernel.h to an 'old' directory as it is no longer
      used by any code within BLIS.

    Allow trsm_l parallelism in the jc loop.
    
    Details:
    - Previously, trsm was consolidating all ways of parallelism into the jr
      loop. This was unnecessary and to some degree detrimental on some
      types of hardware. Now, any parallelism bound for the jc loop will be
      applied to the jc loop, while all other loops' parallelism is funneled
      to the jr loop. Thanks to Devangi Parikh for helping investigate this
      issue and suggesting the fix.
    - NOTE: This change affects only left-side trsm. However, currently
      right-side trsm is currently implemented in terms of the left-side
      case, and thus the change effectively applies to both left and right
      cases.

    Output threading status/params from testsuite.
    
    Details:
    - Updated testsuite to output various parameters related to parallelism
      in BLIS. These parameters include:
      - threading status: disabled, openmp, or pthreads;
      - thread partitioning for jr/ir loops: slab or rr (round-robin);
      - ways of parallelism from environment variables, and also actual
        values used by gemm, herk, trmm_l, trmm_r, trsm_l, and trsm_r for
        square problems (assuming all dimensions are set to 1000);
      - automatic thread factorization parameters.
    - Also output the status of two relatively new configure-time options:
      libmemkind and the sandbox.

    Added option of slab or rr partitioning in jr/ir.
    
    Details:
    - Updated existing macrokernel function names and definitions to
      explicitly use slab assignment of micropanels to threads, then created
      duplicate versions of macrokernels that explicitly use round-robin
      assignment instead of slab. NOTE: As in ac18949, trsm_r macrokernels
      were not substantially updated in this commit because they are
      currently disabled in bli_trsm_front.c.
    - Updated existing packing function (in blk_packm_blk_var1.c) to
      explicitly use slab partitioning, and then duplicated for round-robin.
    - Updated control tree initialization to use the appropriate macrokernel
      and packm function pointers depending on which method (slab or rr) was
      enabled at configure-time.
    - Updated configure script to accept new --thread-part-jrir=[slab|rr]
      option (-m [slab|rr] for short), which allows the user to explicitly
      request either slab or round-robin assignment (partitioning) of
      micropanels to threads.
    - Updated sandbox/ref99 according to above changes.
    - Minor updates to build/add-copyright.py.

    Removed 1h short-circuit from bli_clock_min_diff().
    
    Details:
    - Removed a guard from bli_clock_min_diff() that would return 0 if the
      time delta was greater than 60 minutes. This was originally intended
      to disregard extremely large values under the assumption that the
      user probably didn't intend to run a test that long. However, since
      it is in bli_clock_min_diff(), it doesn't actually help short-circuit
      an implementation that is hanging or looping infinitely, since such
      an implementation would first have to finish before the
      bli_clock_min_diff() is called. Thanks to Kiran Varaganti for
      reporting this issue.

    This is a fix to floating-point exception error for BLIS SGEMM with larger matrix sizes.
    BUG No: CPUPL-197 fixed by Thangaraj Santanu
    The bli_clock_min_diff() function in BLIS assumed that if the time taken is greater than 1 hour then the reading must be wrong. However this is not the case in general, while the other checks such as time taken closer to zero or nsec is ofcourse valid.

    Fixed misleading version query from gcc 7+.
    
    Details:
    - gcc 7 introduced new behavior to the -dumpversion option whereby only
      the major version component is output. However, as part of this
      change, gcc 7 also introduced a new option, -dumpfullversion, which is
      guaranteed to always output the major, minor, and revision numbers. If
      we are using gcc 7 or later, we re-query the version string with this
      new option and then re-parse the result so as to avoid misleading
      output from configure (e.g. using gcc 7.3.0 is reported as 7.7.7).

    Multithreading optimizations for l3 macrokernels.
    
    Details:
    - Adjusted the method by which micropanels are assigned to threads in
      the 2nd (jr) and 1st (ir) loops around the microkernel to (mostly)
      employ contiguous "slab" partitioning rather than interleaved (round
      robin) partitioning. The new partitioning schemes and related details
      for specific families of operations are listed below:
      - gemm: slab partitioning.
      - herk: slab partitioning for region corresponding to non-triangular
              region of C; round robin partitioning for triangular region.
      - trmm: slab partitioning for region corresponding to non-triangular
              region of B; round robin partitioning for triangular region.
              (NOTE: This affects both left- and right-side macrokernels:
              trmm_ll, trmm_lu, trmm_rl, trmm_ru.)
      - trsm: slab partitioning.
              (NOTE: This only affects only left-side macrokernels trsm_ll,
              trsm_lu; right-side macrokernels were not touched.)
      Also note that the previous macrokernels were preserved inside of
      the 'other' directory of each operation family directory (e.g.
      frame/3/gemm/other, frame/3/herk/other, etc).
    - Updated gemm macrokernel in sandbox/ref99 in light of above changes
      and fixed a stale function pointer type in blx_gemm_int.c
      (gemm_voft -> gemm_var_oft).
    - Added standalone test drivers in test/3m4m for herk, trmm, and trsm
      and minor changes to test/3m4m/Makefile.
    - Updated the arguments and definitions of bli_*_get_next_[ab]_upanel()
      and bli_trmm_?_?r_my_iter() macros defined in bli_l3_thrinfo.h.
    - Renamed bli_thread_get_range*() APIs to bli_thread_range*().

    Added statistics-collecting irun.py script.
    
    Details:
    - Added irun.py script to 'build' directory. This irun.py script is a
      python script for repeatedly invoking a test driver executable, such
      as those found in test/3m4m, and replace the performance output column
      with four columns that aggregate statistics. Specifically, the script
      reports the minimum, average, maximum, and standard deviation for each
      problem size. This script is useful especially (though not
      exclusively) when trying to determine the impact of relatively minor
      changes to the code, or other small optimizations that may be
      difficult to distinguish from "noise." One way this "noise" manifests
      is that a test executable may run slightly slower or faster for all
      problem sizes (and all implementations) tested by the executable over
      the life of a single execution. The cause of these minor
      across-the-board pertubations in the overall performance signatures is
      unknown, though we hypothesize that it may relate to any number of
      issues such as operating system scheduling, where in memory the
      program is loaded, or how the CPU clock frequency is throttled at the
      time of execution. Regardless of the source of these subtle
      performance anomalies, the statistical properties reported by the
      irun.py script help the user to more precisely characterize the
      underlying performance exhibited by any given test driver, which
      allows him or her to make better judgments about the true difference
      in performance between two implementations, or minor changes within a
      single implementation.

    Fixed confusing configure message for libmemkind.
    
    Details:
    - Corrected feedback echoed to user by configure when libmemkind is
      found but not explicitly requested. In these cases, configure would
      echo a message that it had received an explicit request to enable
      libmemkind, which was not accurate, even if the end result was the
      same--that libmemkind is enabled by default when it is found. Thanks
      To Devangi Parikh for reporting this issue.

    Various minor cleanups.
    
    Details:
    - Rewrote bli_winsys.c to define bli_setenv() and bli_sleep()
      unconditionally, but differently for Windows and non-Windows, but
      then disabled the definition of bli_setenv() entirely since BLIS
      no longer needs to set environment variables. Updated bli_winsys.h
      accordingly, and call bli_sleep() from within testsuite instead of
      sleep() directly.
    - Use
        #if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS != 200809L)
      instead of
        #if !defined(_POSIX_BARRIERS) || (_POSIX_BARRIERS < 0)
      when guarding against local definition of pthread barrier in
      testsuite. (The description for unistd.h implies that _POSIX_BARRIERS
      should always be set to 200809L when barriers are supported, though I
      won't be surprised if we encounter a case in the future where it is
      set to something else such as 1 while still supported.)
    - Removed old _VERS_CONF_INST definitions and installation rules in
      top-level Makefile. These are no longer needed because we no longer
      output libraries with the version and configuration name as
      substrings.
    - Comment/whitespace updates in Makefile, config.mk.in, common.mk,
      configure, bli_extern_defs.h, and test_libblis.h.
    - Added mention of 1m to README.md and other trivial tweaks.

    Employ "user" cflags for tl Makefile test targets.
    
    Details:
    - Use get-user-cflags-for() to generate cflags when compiling BLAS test
      drivers and BLIS testsuite from top-level Makefile. Meant to include
      these changes in previous commit (4b5437e). Thanks to Isuru Fernando
      for pointing out this oversight.

    Define a cpp macro specific to BLIS compilation.
    
    Details:
    - Tweaked the cflags functions in common.mk so that a new preprocessor
      macro, BLIS_IS_BUILDING_LIBRARY, is defined, but only when BLIS
      itself is being built. This macro will not be defined when, for
      example, the testsuite or example code compiles code local to those
      applications. This was done in part by defining a new cflags function
      get-user-cflags-for(), which is now the designated function for
      application Makefiles if they wish to inherit a basic set of CFLAGS
      from BLIS. (The compiler flags returned are identical to that of
      get-frame-cflags-for() except that -DBLIS_IS_BUILDING_LIBRARY is
      omitted.)
    - Updated all test driver-like makefiles to call get-user-cflags-for()
      instead of get-frame-cflags-for().

    Better thread safety; added threading to testsuite.
    
    Details:
    - Replaced critical sections that were conditional upon multithreading
      being enabled (via pthreads or OpenMP) with unconditional use of
      pthreads mutexes. (Why pthreads? Because BLIS already requires it
      for its initialization mechanism: pthread_once().) This was done in
      bli_error.c, bli_gks.c, bli_l3_ind.c. Also, replaced usage of BLIS's
      mtx_t object and bli_mutex_*() API with pthread mutexes in
      bli_thread.c. The previous status quo could result in a race condition
      if the application called BLIS from more than one thread. The new
      pthread-based code should be completely agnostic to the application's
      threading configuration. Thanks to AMD for bringing to our attention
      the need for a thread-safety review.
    - Added an option to the testsuite to simulate application-level
      multithreading. Specifically, each thread maintains a counter that is
      incremented after each experiment. The thread only executes the
      experiment if: counter % n_threads == thread_id. In other words, the
      threads simply take turns executing each problem experiment. Also,
      POSIX guarantees that fprintf() will not intermingle output, so
      output was switched to fprintf() instead of libblis_test_fprintf().
    - Changed membrk_t objects to use pthread_mutex_t intead of mtx_t and
      replaced use of bli_mutex_init()/_finalize() in bli_membrk.c with
      wrappers to pthread_mutex_init()/_destroy().
    - Changed the implementation of bli_l3_ind_oper_enable_only() to fix
      a race condition; specifically, two threads calling the function with
      the same parameters could lead to a non-deterministic outcome.
    - Added #include <pthread.h> to bli_cpuid.c and moved the same in
      bli_arch.c.
    - Added 'const' to declaration of OPT_MARKER in bli_getopt.c.
    - Added #include <pthread.h> to bli_system.h.
    - Added add-copyright.py script to automate adding new copyright lines
      to (and updating existing lines of) source files.

    - Create a symbolic link to the 'config' directory so that the top-level
      Makefile can find the configs' make_defs.mk files during out-of-tree
      builds.
    - Added additional case handling to out-of-tree scenario to handle
      situations where files 'Makefile', 'common.mk', or 'config' exist but
      are not symbolic links. In such cases, configure warns the user and
      exits.
    - Homogenized various error messages throughout configure.
    - Belated thanks to Victor Eijkhout for requesting the feature added
      in 0f491e9 whereby lesser Makefiles can compile and link against
      an existing installation of BLIS.

    Allow lesser Makefiles to reference installed BLIS.
    
    Details:
    - Updated the build system so that "lesser" Makefiles, such as those in
      belonging to example code or the testsuite, may be run even if the
      directory is orphaned from the original build tree. This allows a
      user to configure, compile, and install BLIS, delete the build tree
      (that is, the source distribution, or the build directory for out-
      of-tree builds) and then compile example or testsuite code and link
      against the installed copy of BLIS (provided the example or testsuite
      directory was preserved or obtained from another source). The only
      requirement is that make be invoked while setting the
      BLIS_INSTALL_PATH variable to the same installation prefix used when
      BLIS was configured. The easiest syntax is:
    
        make BLIS_INSTALL_PATH=/install/prefix
    
      though it's also permissible to set BLIS_INSTALL_PATH as an
      environment variable prior to running 'make'.
    - Updated all lesser Makefiles to implement the new aforementioned build
      behavior.
    - Relocated check-blastest.sh and check-blistest.sh from build to
      blastest and testsuite, respectively, so that if those directories are
      copied elsewhere the user can still run 'make check' locally.
    - Updated docs/Testsuite.md with language that mentions this new option
      of building/linking against an installed copy of BLIS.

    Missing C++ compiler no longer fatal to configure.
    
    Details:
    - Changed configure so that the absence of any C++ compiler from the
      pre-defined search list does not result in an exit. Instead, in this
      situation, the found_cxx variable is assigned 'c++notfound' and the
      error message is changed to remind the user that C++ will not be
      available in the sandbox. Thanks to Devangi Parikh for reporting this
      issue.
    - Also tweaked the message when a C++ compiler *is* found to remind any
      would-be confused user that BLIS will only use C++ if it is needed by
      code in the sandbox.

    Fixed obscure integer size bug in va_arg() usage.
    
    Details:
    - Fixed a bug in the way that the variadic bli_cntx_set_l3_nat_ukrs()
      function was defined. This function is meant to take a microkernel id,
      microkernel datatype, microkernel address, and microkernel preference
      as arguments, and is typically called within the bli_cntx_init_*()
      function defined within a sub-configuration for initializing an
      appropriate context. The problem is with the final argument: the
      microkernel preference. These preferences are actually boolean values,
      0 or 1 (encoded as FALSE or TRUE). Since the variadic function does
      not give the compiler any type information for any variadic arguments,
      they are "promoted" in the course of internal (macroized) processing
      according to default argument promotion rules. Thus, integer literals
      such as 0 and 1 become int and floating-point literals (such as 0.0 or
      1.0) become double. Previous to this commit, we indicated to va_arg()
      that the ukernel preference was a 'bool_t', which is a typedef of
      int64_t on 64-bit systems. On systems where int is defined as 64 bits,
      no problems manifest since int is the same size as the type we passed
      in to va_arg(), but on systems where int is 32 bits, the ukernel
      preference could be misinterpreted as a garbage value. (This was
      observed on a modern armv8 system.) The fix was to interpret the
      bool_t value as int and then immediately typecast it to and store it
      as a bool_t. Special thanks to Devangi Parikh for helping track down
      this issue, including deciphering the use of va_arg() and its
      byzantine treatment of types.
    - Added explicit typecasts for all invocations of va_arg() in
      bli_cntx.c.

    Fixed a very minor memory leak in gks.
    
    Details:
    - Fixed a memory leak in the global kernel structure that resulted in 56
      bytes per configured architecture (of which only 18 are presently
      supported by BLIS). The leak would only manifest if BLIS was
      initialized and then finalized before the application terminated.
      Thanks to Devangi Parikh for helping track down this leak.

    Fixed uncallable bli_finalize().
    
    Details:
    - Previously, bli_finalize_once()--which, like bli_init_once(), was
      implemented in terms of pthread_once()--was using the same
      pthread_once_t control object being used by bli_init(), thus
      guaranteeing that it would never be called as long as BLIS had already
      been initialized. This could manifest as a rather large memory leak to
      any application that attempted to finalize BLIS midway through its
      execution (since BLIS reserves several megabytes of storage for
      packing buffers per thread used). The fix entailed giving each
      function its own pthread_once_t object. Thanks to Devangi Parikh for
      helping track down this very quiet bug.

    Details:
    - Changed the cleanmk target to delete makefile fragments from their new
      home in obj/$(CONFIG_NAME). The old definition worked only because of
      a typo (REFERKN_PATH instead of REFKERN_PATH), and only in the
      non-verbose (V != 1) case.

      did not yet contain the skx sub-configuration, but the previous commit
      included bli_arch.c code copied and pasted from a recent commit that
      does support skx. To keep things consistent, I've removed skx from the

      to stdout. Note that 'check' is unchanged, and thus is now effectively
      a fast version of 'test'.
    - Updated docs/BuildSystem.md to reflect the above change.

    Fixed link error when building only shared library.
    
    Details:
    - Fixed a linker error that occurred when attempting to compile and link
      the testsuite and/or BLAS test drivers after having configured BLIS to
      only generate a shared library (no static library). The chosen
      solution involved
      (1) adding the local library path, $(BASE_LIB_PATH), to the search
          paths for the shared library via the link option
          -Wl,-rpath,$(BASE_LIB_PATH).
      (2) adding a local symlink to $(BASE_LIB_PATH) that uses the .so major
          version number so that ld would find the shared library at
          execution time.
      Thanks to Sajid Ali for reporting this issue, to Devin Matthews for
      pointing out the need for the -rpath option, and to Devangi Parikh for
      helping Sajid isolate the problem.
    - Added #include <ctype.h> to bli_system.h to avoid a compiler warning
      resulting from using toupper() from bli_string.c without a prototype.
      Thanks again to Sajid Ali, whose build log revealed this compiler
      warning.
    - Added '*.so.*' to .gitignore.
    - CREDITS file update.

    Replaced function chooser macros w/ func ptr arrays.
    
    Details:
    - Previously, most object API functions (_oapi.c) used a function
      chooser macro that would expand out to an if-elseif-elseif-else
      conditional that used a num_t datatype to call the appropriate
      type-specific API (_tapi.c). This always felt a little hackish, and
      would get in the way somewhat of addig support for new num_t datatypes
      in the future. So, I've replaced that functionality with code that
      queries a function pointer that is then typecast appropriately. This
      model of function calling was already pervasive for kernels queried
      from the cntx_t structure. It was also already in use in various other
      functions, such as macrokernels, and this commit simply extends that
      pattern.
    - The above change required many new files, mostly header files, that
      define the function types (mostly _ft.h) for the queriable functions
      as well as some source files to define the function pointer arrays and
      their corresponding query functions (_fpa.c). Various other function
      types, mostly for kernel function types, were renamed to reduce the
      potential for confusion with the function types for expert and basic
      (non-expert) typed API functions.
    - Removed definitions for all of the "bli_call_ft_*()" function chooser
      macros from bli_misc_macro_defs.h.

    Format spec and other updates in test, test/3m4m.
    
    Details:
    - Removed the dtime (delta time, or wallclock time) column from the
      matlab output of all test drivers in test, test/3m4m, test/studies.
      This value was rarely (if ever) really needed and usually only served
      to take up screen space.
    - Updated format specifier in test/studies/skx to use %7.2f instead of
      %6.3f.
    - For the test drivers in 'test' directory, added an initial line of
      output that sets last entry of matlab matrix to zero in order to
      induce a pre-allocation of the entire array of performance results.

    Adjusted gflops format spec in testsuite, test/3m4m.
    
    Details:
    - Changed the format specifier for the gflops column in the testsuite
      output from %7.3f to %7.2f. This was done mainly to keep the output
      aligned properly when the expected perfomance exceeded 1000 gflops.
      Also, two decimal places still conveys plenty of precision for all
      practical applications, including just eyeballing performance deltas
      between two executions (let alone two implementations).
    - Changed the format specifier for gflops in the test/3m4m drivers
      from %6.3f to %7.2f (for the same reasons listed above).

    Explicitly typecast return vals in static funcs.
    
    Details:
    - Added explicit typecasting to various functions (mostly static
      functions), primarily those in bli_param_macro_defs.h,
      bli_obj_macro_defs.h, bli_cntx.h, bli_cntl.h, and a few other header
      files.
    - This change was prompted by feedback from Jacob Gorm Hansen, who
      reported that #including "blis.h" from his application caused a
      gcc to output error messages (relating to types being returned
      mismatching the declared return types) when used via the C++ compiler
      front-end. This is the first pass of fixes, and we may need to
      iterate with additional follow-up commits (#233).

    Defined rntm_t to relocate cntx_t.thrloop (#235).
    
    Details:
    - Defined a new struct datatype, rntm_t (runtime), to house the thrloop
      field of the cntx_t (context). The thrloop array holds the number of
      ways of parallelism (thread "splits") to extract per level-3
      algorithmic loop until those values can be used to create a
      corresponding node in the thread control tree (thrinfo_t structure),
      which (for any given level-3 invocation) usually happens by the time
      the macrokernel is called for the first time.
    - Relocating the thrloop from the cntx_t remedies a thread-safety issue
      when invoking level-3 operations from two or more application threads.
      The race condition existed because the cntx_t, a pointer to which is
      usually queried from the global kernel structure (gks), is supposed to
      be a read-only. However, the previous code would write to the cntx_t's
      thrloop field *after* it had been queried, thus violating its read-only
      status. In practice, this would not cause a problem when a sequential
      application made a multithreaded call to BLIS, nor when two or more
      application threads used the same parallelization scheme when calling
      BLIS, because in either case all application theads would be using
      the same ways of parallelism for each loop. The true effects of the
      race condition were limited to situations where two or more application
      theads used *different* parallelization schemes for any given level-3
      call.
    - In remedying the above race condition, the application or calling
      library can now specify the parallelization scheme on a per-call basis.
      All that is required is that the thread encode its request for
      parallelism into the rntm_t struct prior to passing the address of the
      rntm_t to one of the expert interfaces of either the typed or object
      APIs. This allows, for example, one application thread to extract 4-way
      parallelism from a call to gemm while another application thread
      requests 2-way parallelism. Or, two threads could each request 4-way
      parallelism, but from different loops.
    - A rntm_t* parameter has been added to the function signatures of most
      of the level-3 implementation stack (with the most notable exception
      being packm) as well as all level-1v, -1d, -1f, -1m, and -2 expert
      APIs. (A few internal functions gained the rntm_t* parameter even
      though they currently have no use for it, such as bli_l3_packm().)
      This required some internal calls to some of those functions to
      be updated since BLIS was already using those operations internally
      via the expert interfaces. For situations where a rntm_t object is
      not available, such as within packm/unpackm implementations, NULL is
      passed in to the relevant expert interfaces. This is acceptable for
      now since parallelism is not obtained for non-level-3 operations.
    - Revamped how global parallelism is encoded. First, the conventional
      environment variables such as BLIS_NUM_THREADS and BLIS_*_NT  are only
      read once, at library initialization. (Thanks to Nathaniel Smith for
      suggesting this to avoid repeated calls getenv(), which can be slow.)
      Those values are recorded to a global rntm_t object. Public APIs, in
      bli_thread.c, are still available to get/set these values from the
      global rntm_t, though now the "set" functions have additional logic
      to ensure that the values are set in a synchronous manner via a mutex.
      If/when NULL is passed into an expert API (meaning the user opted to
      not provide a custom rntm_t), the values from the global rntm_t are
      copied to a local rntm_t, which is then passed down the function stack.
      Calling a basic API is equivalent to calling the expert APIs with NULL
      for the cntx and rntm parameters, which means the semantic behavior of
      these basic APIs (vis-a-vis multithreading) is unchanged from before.
    - Renamed bli_cntx_set_thrloop_from_env() to bli_rntm_set_ways_for_op()
      and reimplemented, with the function now being able to treat the
      incoming rntm_t in a manner agnostic to its origin--whether it came
      from the application or is an internal copy of the global rntm_t.
    - Removed various global runtime APIs for setting the number of ways of
      parallelism for individual loops (e.g. bli_thread_set_*_nt()) as well
      as the corresponding "get" functions. The new model simplifies these
      interfaces so that one must either set the total number of threads, OR
      set all of the ways of parallelism for each loop simultaneously (in a
      single function call).
    - Updated sandbox/ref99 according to above changes.
    - Rewrote/augmented docs/Multithreading.md to document the three methods
      (and two specific ways within each method) of requesting parallelism
      in BLIS.
    - Removed old, disabled code from bli_l3_thrinfo.c.
    - Whitespace changes to code (e.g. bli_obj.c) and docs/BuildSystem.md.

    Renamed files that distinguish basic/expert APIs.
    
    Details:
    - Renamed various files that were previously named according to a
      "with context" or "without context" convention. For example, the
      following files in frame/3 were renamed:
    
        frame/3/bli_l3_oapi_woc.c -> frame/3/bli_l3_oapi_ba.c
        frame/3/bli_l3_oapi_wc.c  -> frame/3/bli_l3_oapi_ex.c
        frame/3/bli_l3_tapi_woc.c -> frame/3/bli_l3_tapi_ba.c
        frame/3/bli_l3_tapi_wc.c  -> frame/3/bli_l3_tapi_ex.c
    
      Here, the "ba" is for "basic" and "ex" is for "expert". This new
      naming scheme will make more sense especially if/when additional
      expert parameters are added to the expert APIs (typed and object).

    Separated expert, non-expert typed APIs.
    
    Details:
    - Split existing typed APIs into two subsets of interfaces: one for use
      with expert parameters, such as the cntx_t*, and one without. This
      separation was already in place for the object APIs, and after this
      commit the typed and object APIs will have similar expert and non-
      expert APIs. The expert functions will be suffixed with "_ex" just as
      is the case for expert interfaces in the object APIs.
    - Updated internal invocations of typed APIs (functions such as
      bli_?setm() and bli_?scalv()) throughout BLIS to reflect use of the
      new explictly expert APIs.
    - Updated example code in examples/tapi to reflect the existence (and
      usage) of non-expert APIs.
    - Bumped the major soname version number in 'so_version'. While code
      compiled against a previous version/commit will likely still work
      (since the old typed function symbol names still exist in the new API,
      just with one less function argument) the semantics of the function
      have changed if the cntx_t* parameter the application passes in is
      non-NULL. For example, calling bli_daxpyv() with a non-NULL context
      does not behave the same way now as it did before; before, the
      context would be used in the computation, and now the context would
      be ignored since the interace for that function no longer expects a
      context argument.

    Added typed (BLAS-like) API code examples.
    
    Details:
    - Added new example code to examples/tapi demonstrating how to use the
      BLIS typed API. These code examples directly mirror the corresponding
      example code files in examples/oapi. This setup provides a convenient
      opportunity for newcomers to BLIS to compare and contrast the typed
      and object APIs when they are used to perform the same tasks.
    - Minor cleanups to examples/oapi.

    - Changed bli_obj_scalar_attach() so that the scalar value being attached
      is first typecast to the storage datatype of the destination object
      rather than the target datatype.
    - Reformatted function type signatures in bli_obj_scalar.c as well as
      prototypes  in its corresponding header file.

    Fixed bugs in configure's select_cc() function.
    
    Details:
    - This commit fixes several bugs in configure relating to selecting a C
      compiler. By dumb luck, two of the two bugs sort of cancelled each
      other out in most use cases, which manifested as the expected behavior.
      Thanks to Mathieu Poumeyrol for bringing this issue to our attention,
      and to Devin Matthews for suggesting the more portable way of
      capturing both stdout and stderr and suggesting a return code check
      instead of testing stdout/stderr.
    - The first bug: As the values of the compiler search list are iterated
      over, only stderr is captured when querying a compiler with --version
      rather than both stdout and stderr.
    - The second bug: After each query, a conditional attempted to test
      whether the query resulted in anything being output. That conditional
      erroneously was using "-z" instead of "-n" for non-emptiness. Thus,
      most of the time, stderr was empty (because the --version info was
      being output on stdout), and since it was empty, the -z conditional
      (intended to execute only when a compiler was found to be responsive)
      executed.
    - A third bug was also fixed in the way that the merged stdout/stderr
      output was tested for non-emptiness (moving the 'cat' invocation to
      another line and testing the contents of a variable instead).
    - The three bugs above have been fixed as part of a partial rewrite of
      the select_cc() function in terms of a return code check, which
      obviated the need to save the output of stdout and stderr.
    - The fourth bug involved a misnamed variable in the right-hand side
      of a statement intended to prepend CC to search_list when CC was
      non-empty. This typically did not manifest as a bug since usually CC
      (if it was set) was set to a value that was known to work.

    Details:
    - Any preexisting values set to the CFLAGS environment variable (or the

      for later inclusion (prepending, to be precise) along with the
      compiler flags automatically determined by the BLIS build system.
      LDFLAGS is treated in a similar manner.) Thanks to Dave Love for
      requesting this feature in issue #223 and Mathieu Poumeyrol for his
      support on this and a previous related issue.
    - Comment updates to build/config.mk.in.

    Details:
    - Added two presently-disabled cpp blocks in bli_cntx_init_haswell.c to
      easily allow one to switch to a set of column-preferential gemm
      microkernels (in the haswell subconfiguration). The second column-
      preferring block sets the the register blocksizes to their appropriate
      values. However, cache blocksizes are left unchanged, and therefore are
      likely suboptimal. This should be addressed later.

    Implemented castm, castv operations.
    
    Details:
    - Implemented castm and castv operations, which behave like copym and
      copyv except where the obj_t operands can be of different datatypes.
      These new operations, however, unlike copym/copyv, do not build upon
      existing level-1v kernels.
    - Reorganized projm, projv into a 'proj' subdirectory of frame/base (to
      match the newly added frame/base/cast directory).
    - Added new macros to bli_gentfunc_macro_defs.h, _gentprot_macro_defs.h
      that insert GENTFUNC2/GENTPROT2 macros for all non-homogeneous datatype
      combinations. Previously, one had to invoke two additional macros--one
      which mixed domains only and another that included all remaining
      cases--in order to get full type combination coverage.
    - Defined a new static function, bli_set_dims_incs_2m(), to aid in the
      setting of various variables in the implementations of bli_??castm().
      This static function joins others like it in bli_param_macro_defs.h.
    - Comment update to bli_copysc.h.

      A and B objects temporarily to communicate those desired schemas to
      the control tree creation function in blx_gemm_cntl.c. This allows us
      to (henceforth) query the schemas from the control tree rather than
      the context.

      object. Reminder: maximum blocksizes have different meanings in
      different contexts. For register blocksizes, they refer to the packing
      register blocksizes (PACKMR or PACKNR) while for cache blocksizes, they
      refer to the maximum blocksize to use during the final iteration of a
      loop.

    Changed usage of virtual microkernel slots in cntx.
    
    Details:
    - Changed the way virtual microkernels are handled in the context.
      Previously, there were query routines such as bli_cntx_get_l3_ukr_dt()
      which returned the native ukernel for a datatype if the method was
      equal to BLIS_NAT, or the virtual ukernel for that datatype if the
      method was some other value. Going forward, the context native and
      virtual ukernel slots will both be initialized to native ukernel
      function pointers for native execution, and for non-native execution
      the virtual ukernel pointer will be something else. This allows us
      to always query the virtual ukernel slot (from within, say, the
      macrokernel) without needing any logic in the query routine to decide
      which function pointer (native or virtual) to return. (Essentially,
      the logic has been shifted to init-time instead of compute-time.)
      This scheme will also allow generalized virtual ukernels as a way
      to insert extra logic in between the macrokernel and the native
      microkernel.
    - Initialize native contexts (in bli_cntx_ref.c) with native ukernel
      function addresses stored to the virtual ukernel slots pursuant to
      the above policy change.
    - Renamed all static functions that were native/virtual-ambiguous, such
      as bli_cntx_get_l3_ukr_dt() or bli_cntx_l3_ukr_prefers_cols_dt()
      pursuant to the above polilcy change. Those routines now use the
      substring "get_l3_vir_ukr" in their name instead of "get_l3_ukr". All
      of these functions were static functions defined in bli_cntx.h, and
      most uses were in level-3 front-ends and macrokernels.
    - Deprecated anti_pref bool_t in context, along with related functions
      such as bli_cntx_l3_ukr_eff_dislikes_storage_of(), now that 1m's
      panel-block execution is disabled.

    Renamed 1m packm kernels from _1e to _1er.
    
    Details:
    - Renamed the reference packm kernels used by 1m. Previously, they used
      a _1e suffix, which was confusing since they packed to both 1e and 1r
      schemas. This was likely an artifact of the time when there were
      separate kernels for each schema before I decided to combine them into
      a single function (per datatype and panel dimension), and the 1e
      functions were the ones to inherit the 1r functionality. The kernels
      have now been renamed to use a _1er suffix.

    Implemented bli_acquire_mpart(), added example code.
    
    Details:
    - Implemented bli_acquire_mpart(), a general-purpose submatrix view
      function that will alias an obj_t to be a submatrix "view" of an
      existing obj_t.
    - Renumbered examples in examples/oapi and inserted a new example file,
      03obj_view.c, which shows how to use bli_acquire_mpart() to obtain
      submatrix views of existing objects, which can then be used to
      indirectly modify the parent object.

    Fixed broken input.operations.fast.
    
    Details:
    - Removed three input lines from input.operations.fast (labeled
      "test sequential micro-kernel") that I intended to remove in bd02c4e.
      These lines prevented 'make check' (and 'make checkblis-fast') from
      completing correctly. Note: This bug was fixed in 3df39b3, but that
      commit has not yet been merged into master, hence this redundant
      commit. Thanks to Robert van de Geijn for reporting this issue.

    Fixed undefined ref in steamroller/excavator configs.
    
    Details:
    - Fixed erroneous calls to bli_cntx_init_piledriver_ref() in
      bli_cntx_init_steamroller() and bli_cntx_init_excavator(), which
      should have been to their respectively-named bli_cntx_init_*()
      functions instead. Thanks to qnerd for bringing these bugs to our
      attention.

    Implemented bli_setrm, _setim, _setrv, _setiv.
    
    Details:
    - Defined new wrappers to setm/setv operations in frame/base/bli_setri.c
      that will target only the real or only the imaginary parts of a
      matrix/vector object.
    - Updated bli_obj_real_part() so that the complex-specific portions of
      the function are not executed if the object is real.
    - Defined bli_obj_imag_part().
      - Caveat: If bli_obj_imag_part() is called on a real object, it does
        nothing, leaving the destination object untouched. The caller must
        take care to only call the function on complex objects.
    - Reordered some of the static functions in bli_obj_macro_defs.h related
      to aliasing.

    Fixed bug in bli_dt_proj_to_complex().
    
    Details:
    - Fixed a bug identical to the one fixed in 0a4a27e, except this time in
      the bli_obj_param_defs.h header file. It looks like the only consumers
      of this static function were in bli_l0_oapi.c, and so this may not have
      been manifesting (yet).

    Enforce consistent datatypes in most object APIs.
    
    Details:
    - Added logic to level-1v, -1d, -1f, -1m, -2, and -3 operations' _check()
      functions to ensure that all operands are of the same datatype. There
      are some exceptions that were left out, such as the _check() function
      for the various norm operations since they have a different idea of
      datatype consistency (ie: the norm object must be the real projection
      of the primary input vector/matrix object).

    Defined/implemented bli_projv().
    
    Details:
    - Added an implementation for bli_projv() to go along with the
      implementation of bli_projm() added in 0a4a27e. The only difference
      between the two is that bli_projv() may only be used on vectors,
      whereas bli_projm() is general-purpose.
    - Added a _check() function corresponding to bli_projv().

        bli_param_map_char_to_blis_dt()
        bli_param_map_blis_to_char_dt()
      which will map a char to its corresponding num_t, or vice versa.

    Defined/implemented bli_projm().
    
    Details:
    - Defined a new operation in frame/base/bli_proj.c, bli_projm(), which
      behaves like bli_copym(), except that operands a and b are allowed to
      contain data of differing domains (e.g. a is real while b is complex,
      or vice versa). The file is named bli_proj.c, rather than bli_projm.c,
      with the intention that a 'v' vector version of the function may be
      added to the same file (at some point in the future).
    - Added supporting bli_check_*() functions in bli_check.c to confirm
      consistent precisions between to datatypes/objects, as well as the
      appropriate error message in bli_error.c and a new error code in
      bli_type_defs.h.
    - Wrote a bli_projm_check() function to go along with bli_projm().
    - Defined static function bli_obj_real_part() in bli_obj_macro_defs.h,
      which will initialize an obj_t alias to the real part of the source
      object.
    - Fixed a bug in the static function bli_dt_proj_to_complex(), found
      in bli_param_macro_defs.h. Thankfully, there were no calls to the
      function to produce buggy behavior.

    Fixed recently broken input.operations.fast.
    
    Details:
    - Removed "test sequential front-end" lines from microkernel test
      entries of input.operations.fast. This change was meant for inclusion
      in bd02c4e but was missed due to slightly different wording of the
      comment (I used "sed //d" to remove the lines). This fixes the broken
      'make checkblis-fast' (and 'make check') targets.

    Cosmetic fix to configure output in config.mk.
    
    Details:
    - Fixed configure so that MK_ENABLE_MEMKIND is assigned "no" when the
      option is disabled due to libmemkind not being present. This wasn't
      affecting anything since the one use of the variable (in common.mk)
      was formulated as "ifeq ($(MK_ENABLE_MEMKIND),yes)". That is, the
      variable being empty was effectively equivalent to it being set to
      "no".
    - Comment updates to build/config.mk.in, common.mk.

    Cleanups to testsuite, input.operations format.
    
    Details:
    - Removed the line in each operation entry in input.operations titled
      "test sequential front-end" and the corresponding support for the lines
      in the testsuite input parsing code. This line was included in the some
      of the earliest versions of the testsuite, back when I intended to
      eventually have separate multithreaded APIs. Specifically, I envisioned
      that multithreaded and sequential testing could be enabled or disabled
      on an operation level. However, BLIS evolved in a different direction
      and still does not have multithreaded-specific APIs (even if it will
      eventually someday). But even if it did have such APIs, I doubt I would
      allow the user to enable/disable them on an operation level. Thus, this
      was a zombie future parameter that was never used and never made sense
      to begin with. The one instance of the front_seq variable, used in the
      various libblis_test_<operation>() functions to guard the call to the
      operation test driver, that remains was commented out instead of
      deleted so that someday it could be easily changed via sed, if desired.
    - Various minor cleanups to the testsuite code, including consolidating
      use of DISABLE and DISABLE_ALL and reexpressing certain conditional
      expressions in the libblis_test_<operation>() functions in terms of
      boolean functions.

    Disabled indirect blacklisting (issue #214).
    
    Details:
    - Return early from function, pass_config_kernel_registries(), that
      implements indirect blacklisting of subconfigurations (during pass 0).
      In short, I realized that indirect blacklisting is not needed in the
      situations I envisioned, and can actually cause problems under certain
      circumstances. Thanks to Tony Skjellum for reporting the issue (#214)
      that led to this commit, and to Devin Matthews for prompting me to
      realize that indirect blacklisting was unnecessary, at least as
      originally envisioned.

    Updated setting/querying pack schema (cntx->cntl).
    
    - Query pack schemas in level-3 bli_*_front() functions and store those
      values in the schema bitfields of the correponding obj_t's when the
      cntx's method is not BLIS_NAT. (When method is BLIS_NAT, the default
      native schemas are stored to the obj_t's.)
    - In bli_l3_cntl_create_if(), query the schemas stored to the obj_t's in
      bli_*_front(), clear the schema bitfields, and pass the queried values
      into bli_gemm_cntl_create() and bli_trsm_cntl_create().
    - Updated APIs for bli_gemm_cntl_create() and bli_trsm_cntl_create() to
      take schemas for A and B, and use these values to initialize the
      appropriate control tree nodes. (Also cpp-disabled the panel-block cntl
      tree creation variant, bli_gemmpb_cntl_create(), as it has not been
      employed by BLIS in quite some time.)
    - Simplified querying of schema in bli_packm_init() thanks to above
      changes.
    - Updated openmp and pthreads definitions of bli_l3_thread_decorator()
      so that thread-local aliases of matrix operands are guaranteed, even
      if aliasing is disabled within the internal back-end functions (e.g.
      bli_gemm_int.c). Also added a comment to bli_thrcomm_single.c
      explaining why the extra aliasing is not needed there.
    - Change bli_gemm() and level-3 friends so that the operation's ind()
      function is called only if all matrix operands have the same datatype,
      and only if that datatype is complex. The former condition is needed
      in preparation for work related to mixed domain operands, while the
      latter helps with readability, especially for those who don't want to
      venture into frame/ind.
    - Reshuffled arguments in bli_cntx_set_thrloop_from_env() to be
      consistent with BLIS calling conventions (modified argument(s) are
      last), and updated all invocations in the level-3 _front() functions.
    - Comment updates to bli_cntx_set_thrloop_from_env().

      that it would be thought of as a "reference" sandbox. I kept the "99"
      to differientiate it from future reference sandboxes that may be
      written in another language (such as C++).
    - Updates to sandbox/ref99/README.md.

    Initial implementation of c99 "reference" sandbox.
    
    Details:
    - Added a c99 sandbox (in sandbox/c99) to serve as a starting point for
      others looking to experiment with alternative implementations of gemm
      in BLIS. Note that this sandbox implementation is a first draft and
      will be refined over time.
    - Minor updates to Makefile and common.mk to restrict what source files
      get recompiled when sandbox files are touched.
    - Added an initial draft of a README.md in sandbox/c99.

    Support alternative gemm implementation sandboxes.
    
    Detail:
    - configure:
      - add support for --enable-sandbox=NAME to configure script, where NAME
        is a subdirectory of a new 'sandbox' directory that contains an
        alternative implementation of gemm. (For now, only implementations of
        gemm may be provided via a sandbox.);
      - add support for C++ compiler. C++ compilers are handled in a manner
        similar to that of C compilers, in that a default search order is
        used, and that CXX is searched for first, if the variable is set. In
        practice, the C++ compiler that is selected should correspond to the
        selected C compiler. (Example: If gcc is selected for C, g++ should
        be selected for C++.) The result of the search is output to config.mk
        via build/config.mk.in. NOTE: The use of C++ in BLIS is still
        hypothetical, but may eventually move to being experimental. This
        support was intended only for use of C++ within a gemm sandbox.
    - build/config.mk.in:
      - define SANDBOX variable containing sandbox subdirectory name.
    - build/bli_config.in:
      - define either of the BLIS_ENABLE_SANDBOX or BLIS_DISABLE_SANDBOX
        macros in bli_config.h.
    - common.mk:
      - include makefile fragments that were propagated into the specified
        sandbox subdirectory;
      - generate different CFLAGS for sandboxes, as well as a separate
        CXXFLAGS variable for sandboxes when C++ source files are compiled;
      - isolate into a single location lists of file suffixes for various
        purposes.
      - reorganized/clean up code related to identifying header files and
        paths.
    - Makefile:
      - generate object filepaths for and compile source code files found in
        sandbox sub-directory;
      - remove makefile fragments placed in sandbox sub-directory (cleanmk);
      - various other cleanups.
    - Added .cc, .cpp, and .cxx to list of suffixes of files to recognize in
      makefile fragments (via build/gen-make-frags/suffix_list).
    - Updated blis.h to conditionally #include bli_sandbox.h (via a new file,
      bli_sbox.h), which each sandbox is assumed to use for any type
      definitions and function prototypes it wishes to export out to blis.h.
    - Conditionally disable bli_gemmnat() implementation in frame/3 when
      BLIS_ENABLE_SANDBOX is defined.

    Updated types of bli_is_[un]aligned_to() functions.
    
    Details:
    - Changed the void* arguments of the following static functions:
        bli_is_aligned_to()
        bli_is_unaligned_to()
        bli_offset_past_alignment()
      to siz_t, and the return type of bli_offset_past_alignment() from
      guint_t to siz_t. This allows for more versatile usage of these
      functions (e.g. when aligning both pointers and leading dimension).
    - Updated all invocations of these functions, mostly in kernels/penryn
      but also in kernels/bgq, to include explicit typecasts to siz_t when
      pointer arguments are passed in.
    - Thanks to Devin Matthews for pointing out this potential bug (via issue
      #211).
    - Deleted a few trailing spaces in various penryn kernels.
    - Removed duplicate instances of the words "derived" and "THEORY" from
      various kernel license headers, likely from a malformed recursive sed
      performed long ago.

    Cache hardware's arch_t id after querying once.
    
    Details:
    - Added logic to bli_arch.c that will call what was previously the body
      of bli_arch_query_id() only once and then cache the value in a static
      variable local to the file. (Previously, the arch_t associated with
      the hardware/configuration was queried every time bli_arch_query_id()
      was called, which was at least once per level-3 function call. Thanks
      to Devin Matthews for suggesting this feature via issue #175.
    - Added -lpthread to the compile/link command line of the compiler
      invocation that compiles build/detect/config/config_detect.c, which
      prints the string identifying the detected configuration, since it
      is now needed due to new pthread_once() logic in bli_arch.c.
    - Implementation note: I chose to implement this arch_t caching feature
      via pthread_once(), using a separate pthread_once_t variable local to
      the file, rather than calling bli_init_once(). The reason is that I
      did not want to require bli_init() as a prerequisite to this function.
      bli_init() already calls several sub-components, some of which make use
      of bli_arch_query_id(), and therefore it would be easy to fall into a
      circular self-init situation (which usually causes pthreads to hang
      indefinitely).

    Fixed clobber list bug in ARMv8 ukernel

    Inserted missing integer typecasting into ukernels.
    
    Details:
    - Inserted missing safeguards into most microkernels to ensure that the
      integers read by the microkernel's assembly instructions are of the
      appropriate size. In many cases, this bug was going undetected likely
      because the compiler was inserting zero padding before the integers
      in the calling function, allowing the assembly code to read 64-bits
      in a way that did not corrupt the "lower" 32 integer bits with garbage
      in the higher bits. Thanks to Francisco Igual and Devangi Parikh for
      finding this issue.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Wed May 16 12:46:57 2018 -0500

    Fixed a bug in determining default integer size.
    
    Details:
    - Fixed a bug that would cause configurations to inadvertantly define
      their integers to be 32 bits when those environments actually call for
      64-bit integers. While either BLIS_ARCH_64 or BLIS_ARCH_32 is defined
      in bli_system.h (based on whether preprocessor macros such as __x86_64
      or __aarch64__ are defined by the environment), bli_system.h was being
      #included *after* bli_config_macro_defs.h, in which the BLIS_ARCH_64
      macro was used to choose an integer type size in the event that
      BLIS_INT_TYPE_SIZE was not already defined by configure via
      bli_config.h. And due to the structure of the cpp code in that file,
      the 32-bit integer case was being chosen. Thanks to Francisco Igual
      and Devangi Parikh for their help in isolating this bug.
    - Moved the #include of hbwmalloc.h and related preprocessor code to
      bli_kernel_macro_defs.h to facilitate the reshuffling of the #include
      for bli_system.h in blis.h.

    Fix shared library builds on platforms other than Linux and macOS (#209)
    
    * Fix detection of systems other than Linux and macOS
    
    The way the logic is currently laid out, any platform that isn't Linux
    gets assigned the .dylib shared library extension and the macOS-specific
    compiler flags. This reverses the logic to check for macOS first, and
    have the fallback use the Linux definitions, which apply to most other
    systems as well.
    
    * Use SHLIB_EXT instead of SO_SUF
    
    The former is more standard, as jakirkham pointed out in a comment.

      configure script.

    Communicate cc, cc_vendor to make via config.mk.
    
    Details:
    - Historically, the compiler selection has happened statically in the
      various make_defs.mk and would only be overriden by setting CC (either
      prior to running configure or as a configure argument). However, in
      the last couple months, configure has evolved to contain rather
      sophisticated compiler detection logic for the purposes of blacklisting
      sub-configurations. It only makes sense that configure now fully take
      over the responsibility of selecting a compiler from the GNU make side
      of the build system. Thanks to Alex Arslan for his help exposing this
      issue.
    - Substitute found_cc into CC in config.mk via configure.
    - Set a new variable, CC_VENDOR, in config.mk via substitution from
      configure, and disable the corresponding CC_VENDOR code in common.mk.
    - Disabled default compiler selection (usually gcc) in the sub-configs'
      various make_def.mk files.

    Change compiler search order on OpenBSD.
    
    Details:
    - Set a compiler search list (and order) as a function of the OS detected
      via 'uname -s'. By default, this list and order is 'gcc clang cc' for
      Linux and Darwin (OS X), and any other OS except OpenBSD). On OpenBSD,
      we use 'cc gcc clang' because OpenBSD's default installation of gcc
      (4.2.1) is too old for BLIS. Thanks to Alex Arslan for reporting this
      issue and suggesting a fix.

    - Updated --help text and configure's feedback messages reporting the

    - Changed the order of build product installation so that headers are
      installed last, after libraries and symlinks.

    Adopt Linux-like .so versioning at install-time.
    
    Details:
    - Changed the naming conventions used for installed libraries and
      symlinks to more closely mirror patterns used by typical GNU/Linux
      libraries. Whereas previously static and shared libraries were
      installed and symlinked as follows:
    
        (library) libblis-0.3.2-15-haswell.a
        (library) libblis-0.3.2-15-haswell.so
        (symlink) libblis.a -> libblis-0.3.2-15-haswell.a
        (symlink) libblis.so -> libblis-0.3.2-15-haswell.so
    
      we now use the following naming conventions:
    
        (library) libblis.a
        (symlink) libblis.so -> libblis.so.0.1.2
        (symlink) libblis.so.0 -> libblis.so.0.1.2
        (library) libblis.so.0.1.2
    
      where 0.1.2 indicates shared library major, minor, and build versions
      of 0, 1, and 2, respectively. The conventional version string can
      still be queried by linking to the library in question and then calling
      bli_info_get_version_str(). (The testsuite binary does this
      automatically at startup.)
    - Added logic to common.mk to set the soname field in the shared library
      via the -soname linker flag.
    - Added a 'so_version' file to the top-level directory containing two
      lines. The first line specifies the .so major version number, and the
      second line specifies the minor and build version numbers joined with
      a '.'. This file is read by configure and those values substituted
      into build/config.mk.in to define SO_MAJOR, SO_MINORB, and SO_MMB
      variables.

    Tweaks to top-level clean and distclean targets.
    
    Details:
    - Moved the removal of bli_config.h from cleanh to distclean.
    - Removed cleantest as a dependency of clean.

    Renamed (shortened) a few build system variables.
    
    Details:
    - Renamed the following variables in config.mk (via build/config.mk.in):
        BLIS_ENABLE_VERBOSE_MAKE_OUTPUT -> ENABLE_VERBOSE
        BLIS_ENABLE_STATIC_BUILD        -> MK_ENABLE_STATIC
        BLIS_ENABLE_SHARED_BUILD        -> MK_ENABLE_SHARED
        BLIS_ENABLE_BLAS2BLIS           -> MK_ENABLE_BLAS
        BLIS_ENABLE_CBLAS               -> MK_ENABLE_CBLAS
        BLIS_ENABLE_MEMKIND             -> MK_ENABLE_MEMKIND
      and also renamed all uses of these variables in makefiles and makefile
      fragments. Notice that we use the "MK_" prefix so that those variables
      can be easily differentiated (such as via grep) from their "BLIS_" C
      preprocessor macro counterparts.
    - Other whitespace changes to build/config.mk.in.
    - Renamed the following C preprocessor macros in bli_config.h (via
      build/bli_config.h.in):
        BLIS_ENABLE_BLAS2BLIS        -> BLIS_ENABLE_BLAS
        BLIS_DISABLE_BLAS2BLIS       -> BLIS_DISABLE_BLAS
        BLIS_BLAS2BLIS_INT_TYPE_SIZE -> BLIS_BLAS_INT_TYPE_SIZE
      and also renamed all relevant uses of these macros in BLIS source
      files.
    - Renamed "blas2blis" variable occurrences in configure to "blas", as
      was done in build/config.mk.in and build/bli_config.h.in.
    - Renamed the following functions in frame/base/bli_info.c:
        bli_info_get_enable_blas2blis() -> bli_info_get_enable_blas()
        bli_info_get_blas2blis_int_type_size()
                                        -> bli_info_get_blas_int_type_size()
    - Remove bli_config.h during 'make cleanh' target of top-level Makefile.

    Converted function-like macros to static functions.
    
    Details:
    - Converted most C preprocessor macros in bli_param_macro_defs.h and
      bli_obj_macro_defs.h to static functions.
    - Reshuffled some functions/macros to bli_misc_macro_defs.h and also
      between bli_param_macro_defs.h and bli_obj_macro_defs.h.
    - Changed obj_t-initializing macros in bli_type_defs.h to static
      functions.
    - Removed some old references to BLIS_TWO and BLIS_MINUS_TWO from
      bli_constants.h.
    - Whitespace changes in select files (four spaces to single tab).

    Add configure support for --libdir, --includedir.
    
    Details:
    - Added support for two new configure options: --libdir and --includedir.
      They specify the precise install directories for libraries and header
      files, respectively, and override any location implied by the --prefix
      option (including the default install prefix, if --prefix was not
      given). Thanks to Nico Schlömer for suggesting this via issue #195.
    - Removed the INSTALL_PREFIX definition/anchor from build/config.mk.in
      and replaced it with corresponding definitions/anchors for libdir and
      includedir.
    - Updated top-level Makefile to use the new variables, INSTALL_LIBDIR
      and INSTALL_INCDIR, instead of INSTALL_PREFIX (which is now no longer
      needed by make).
    - Set default sane values for INSTALL_LIBDIR and INSTALL_INCDIR in
      common.mk when configure has not been run, as is already done for
      DIST_PATH. This is to safeguard against statements in the top-level
      Makefile that use 'find' to locate old libraries and headers for the
      uninstall targets, which run regardless of make target. Without setting
      INSTALL_LIBDIR and INSTALL_INCDIR, those variables are empty and the
      'find' ends up looking at '/', which is obviously not what we want.
      (Also enclosed those definitions in an IS_CONFIGURED guard so that they
      won't get evaluated unless configure has been run.)
    - Rearranged "ifeq ($(IS_CONFIGURED),yes)" conditionals in Makefile to
      reduce occurrences and separated "local" and top-level components of
      cleanblastest and cleanblistest targets to improve readability.
    - Adjusted out-of-tree builds so that they are no longer oblivious to
      the .git directories, if present, and thus now properly augment version
      strings with the appropriate patch number.
    - Include missing version string in 'configure --help' output.

    Allow 'make clean' and friends without configuring.
    
    Details:
    - Modified top-level Makefile so that a user can run 'make distclean',
      'make clean', or any of the other clean-related targets prior to
      running configure (or after a previous 'make distclean'). Thanks to
      Nico Schlömer for suggesting this via issue #197.
    - Made the cleanblastest and cleanblistest more comprehensive in that
      they now clean out build products that would have resulted from local
      compilation (ie: builds performed within the 'blastest' or 'testsuite'
      directories).
    - Added "cc" to list of expected compiler "vendors" since the CC variable
      seems to automatically be set to "cc" on Ubuntu 16.04 (which is just an
      alias to gcc).
    - Comment update to build/config.mk.in.

    No longer update version file during configure.
    
    Details:
    - Recycled the core functionality of build/update-version-file.sh into a
      function in configure, disabling the updating of the 'version' file in
      the process. Instead of writing the patched version string back to the
      version file and then reading it again from within configure, the
      patched version string is now saved directly to a variable in the main()
      function in configure. This will prevent developers from accidentally
      committing configure-induced changes to the version file in between
      releases.

    AMD specific optimizations for target 'zen' (#194)
    
    Re-enabled AMD-specific optimizations for zen.
    
    Details:
    - Re-enabled Zen-specific cache blocksizes for 'zen' sub-configuration.
    - Re-enabled small matrix gemm optimization for 'zen'.
    - These were both temporarily disabled during a previous merge simply due to lack of Zen hardware for testing.

    Add setijm, getijm operations.
    
    Details:
    - Added bli_setgetijm.c, which defines bli_setijm(), bli_getijm(), and
      related functions that can be used to read and write individual
      elements of an obj_t.
    - Defined a new function, bli_obj_create_conf_to(), in bli_obj.c that will
      create a new object with dimensions conformal to an existing object.
      Transposition and conjugation states on the existing object are ignored,
      as are structure and uplo fields.
    - Defined a new function, bli_datatype_string(), in bli_obj.c that returns
      a char* to a string representation of the name of each num_t datatype.
      For example, BLIS_DOUBLE is "double" and BLIS_DCOMPLEX is "dcomplex".
      BLIS_INT is included (as "int"), but BLIS_CONSTANT is not, and thus is
      not a valid input argument to bli_datatype_string().
    - Added calls to bli_init_once() to various functions in bli_obj.c, the
      most important of which was bli_obj_create_without_buffer().
    - Removed unintended/extra newline from the end of printv output.
    - Whitespace changes to
      - frame/base/bli_machval.c
      - frame/base/bli_machval.h
      - frame/0/copysc/bli_copysc.c
    - Trivial changes to README.md and common.mk.

      to myself, but also may become useful if/when others take over
      development and administration of the project.

    Updates to knl kernels and related code.
    
    Details:
    - Imported the 24x16 knl sgemm microkernel (and its corresonding spackm
      kernel) from TBLIS and enabled its use in the knl sub-config. Also
      Added sgemm microkernel prototype to bli_kernels_knl.h.
    - Updated dgemm and dpackm microkernels from TBLIS, which included an
      important change regarding the offsets array (changed from extern
      declaration to static declaration/definition).
    - Activated use of level-1v and -1f zen kernels in skx and knl
      sub-configs.
    - Removed some old macros no longer needed in bli_family_skx.h now that
      libmemkind support exists in configure.
    - Moved bli_avx512_macros.h to frame/include and adjusted #includes in
      skx and knl kernels accordingly.
    - Moved unused kernels in kernels/knl/3 to kernels/knl/3/other
      directory.
    - Fixed a minor bug in the 'make' output per compile when verboseness
      is not turned on. The rule-generating function 'make-kernel-rule' was
      previously passing in the name of the config, rather than the name of
      the kernel set returned by get-config-for-kset, which could give
      misleading information to the user when the kconfig_map mapped a
      kernel set to a sub-configuration that did not share the same name.
      (This didn't affect the CFLAGS that were actually used.)
    - Updated test/3m4m/Makefile, removing acml targets and renaming the
      remaining targets.

    Retired haswell gemm microkernels.
    
    Details:
    - Moved microkernels in kernels/haswell/3 to kernels/haswell/3/old. These
      microkernels were no longer being used and only sowed confusion to
      anyone inspecting the repository without being fully cognizant of the
      build system and how it works (and sometimes even to those who wrote
      the build system). Note that the haswell configuration currently
      employs the zen microkernels.

    Cleaned up assembler version query on OS X.
    
    Details:
    - Swiched from querying version of 'objdump' to 'as' (e.g. the
      assembler).
    - Fixed the outputting of the version of 'as' on OS X, which required
      this beauty:
        ...=$(as -v /dev/null -o /dev/null 2>&1)
    - Only add sub-configs to blacklist if the sub-config hasn't already
      been added.

    Added support for blacklisting via the assembler.
    
    Details:
    - Added logic to configure that attempts to assemble various small files
      containing select instructions designed to reveal whether binutils
      (specifically, the assembler) supports emitting those instruction sets.
      This information provides additional opportunities to blacklist sub-
      configurations that are unsupported by the environment. Thanks to Devin
      Matthews for pointing me towards a similar solution in TBLIS as an
      example.
    - Various other cleanups in configure.
    - Reorganized the detection code in the 'build' directory, bringing the
      "auto-detect" configuration detection, libmemkind detection, and new
      instruction set detection codes into a single new subdirectory named
      'detect'.

    Fixed failure to honor CC= argument to configure.
    
    Details:
    - Fixed a failure to observe the value of CC when selecting the compiler
      in configure. Thanks to Devangi Parikh for reporting this bug.
    - The semantics now also work for the CC environment variable. That is,
      if CC is set prior to running configure, that value is used, but will
      be overridden by specifying the CC= argument to configure. If the CC
      environment variable is not set, the CC= value is used. If neither the
      environment variable nor CC= are specified, then the choice is made
      internally to configure: first attempting to find gcc, then clang, and
      then cc.

    Fixed libmemkind dependency for x86_64.
    
    Details:
    - Removed some old conditional code in config/knl/make_defs.mk that
      added -lmemkind to LDFLAGS if DEBUG_TYPE was not 'sde' and inserted
      code into common.mk that affirmatively filters out -lmemkind from
      LDFLAGS if DEBUG_TYPE is 'sde'. (Thanks to Dave Love for reporting
      this issue.) Other minor cleanups to neighboring code in common.mk.
    - Updated CRVECFLAGS in knl/make_defs.mk to be based on -march=knl,
      and then AVX-512 functionality is manually removed via various
      -mno-avx512* flags. Also, make the setting of CRVECFLAGS conditional
      on CC_VENDOR. Similar change to skx/make_defs.mk.
    - Comment/whitespace updates.

    Track separate ref kernel flags for each sub-config.
    
    Details:
    - Renamed CVECFLAGS variables in sub-configurations' make_defs.mk files
      to CKVECFLAGS.
    - Added default defintions of two new make variables to most sub-
      configurations' make_defs.mk files--CROPTFLAGS and CRVECFLAGS--
      which correspond to reference kernel analogues of the CKOPTFLAGS
      and CKVECFLAGS, which track optimization and vectorization flags for
      optimized kernels. Currently, two sub-configurations (knl and skx)
      explicitly set CRVECFLAGS to non-default values (using AVX2 instead of
      AVX-512 for reference kernels. Thanks to Jeff Hammond, whose feedback
      prompted me to make this change (issue #187).
    - Changed common.mk so that the get-refkern-cflags-for function returns
      the flags associated with the given sub-configuration's CROPTFLAGS
      and CRVECFLAGS (instead of CKOPTFLAGS and CKVECFLAGS).

    De-verbosify makefile fragment generation.
    
    Details:
    - Changed from -v1 to -v0 when calling gen-make-frag.sh from configure.
      The directory-by-directory recursive output didn't add much value to
      the user, so now we just echo a line for each top-level directory into
      which we will recurse (e.g. 'config', 'ref_kernels', 'frame', etc.).
      This also helps keep more interesting information (from earlier in the
      execution of configure) from scrolling out of the terminal window.

    Added 64-bit integer support to BLAS test drivers.
    
    Details:
    - Updated the build system and BLAS test drivers to use 64-bit integers
      when BLIS is configured for 64-bit integers in the BLAS layer. Also
      updated blastest/Makefile accordingly. Thanks to Dave Love for
      reporting the need for this feature.
    - Added a 'check' target to blastest/Makefile so that the user can see
      a summary of the tests.
    - Commented out the initial definition of INCLUDE_PATHS in common.mk,
      which was used pre-monolithic header, back when BLIS needed paths to
      *all* headers, rather than just a select few. This line is no longer
      needed since the value of INCLUDE_PATHS is overwritten by a later
      definition limited to only the header paths that are needed now.

    Adjusted CFLAGS used to compile bli_cntx_ref.c.
    
    Details:
    - Removed CKOPTFLAGS and CVECFLAGS from the set of CFLAGS used to
      compile bli_cntx_ref.c for each configuration. This is necessary
      because the file defines functions like bli_cntx_init_skx_ref(),
      which are called during BLIS's initialization of the global kernel
      structure, potentially being executed by an architecture that lacks
      the instruction set used to compile the kernels for, in this example,
      skx, which would lead to an illegal instruction error. Thanks to
      Dave Love for reporting this issue.
    - Further adjusted CFLAGS used when compiling code in the 'config'
      directory (e.g. bli_cntx_init_skx.c) as well as code in 'frame' so
      as to avoid the aforementioned issue.

    Added color-coding to 'make check' output.
    
    Details:
    - Added color coding to output of check-blistest.sh, check-blastest.sh
      scripts. Success messages are coded green and failure are coded red.
      This helps draw the eye toward those messages as the 'make checkblis',
      'make checkblis-fast', and 'make checkblas' targets are executed.
    - Changed top-level Makefile so that execution will not halt if
      'checkblis', 'checkblis-fast', or 'checkblas' targets fail, which
      means that the second of the two tests (BLIS and BLAS) run by
      'make check' will run even if the first test fails.

    Added skx, knl to x86_64 configuration family.
    
    Details:
    - Added 'skx' and 'knl' sub-configurations to the 'x86_64' configuration
      family in the config_registry file.
    - Added logic to configure that avoids committing certain sub-configs to
      the configuration/kernel registries if those sub-configs cannot be
      handled properly by the chosen compiler. (This was modeled after
      similar logic in TBLIS's configure; thanks to Devin Matthews for
      pointing this out.) First, the compiler and its version are inspected
      and, based on the results, certain configurations are added to a
      "blacklist". Then, as the configuration registries are being created,
      configurations and/or kernels that match items in the blacklist are
      skipped over and not commited to the registries. Under certain
      circumstances, omitting a blacklisted configuration will indirectly
      invalidate other configurations due to the loss of availability of
      the original blacklisted configuration's kernel set. This additional
      indirect blacklist is also accounted for.
    - Added output to the beginning of configure that echos information
      about the chosen compiler as well as the configurations that are
      blacklisted and must be stripped from the registries.
    - Various other cleanups in configure, especially with respect to
      explicitly declaring local variables in functions.
    - Comment updates to config/zen/make_defs.mk regarding choice of -march
      flags based on compiler version.

    Fixed 64b type mismatch warning in cblas_xerbla.c.
    
    Details:
    - Fixed a compiler warning concerning a type mismatch between the
      format specifier of the printf() call in cblas_xerbla.c and its
      corresponding (info) argument. The warning manifested when the CBLAS
      layer was enabled and the BLAS/CBLAS integer type siwas is set to 64
      (the default is 32). The warning was fixed by changing the specifier
      from %d to %jd and typecasting the argument to intmax_t. Thanks to
      Dave Love for reporting this issue and submitting the patch.

    Row storage optimizations to zen dotxf kernels.
    
    Details:
    - Split the main loop bodies of zen's [sd]dotxf kernels into two cases:
      one to handle a column-stored matrix A and one to handle a row-stored
      matrix A. This allows vector instructions to be employed even if A is
      stored by rows (and A^T appears stored as columns). Both storage cases
      use a common edge case loop. Thanks to Devin Matthews for this idea
      and for prototyping the change needed for sdotxf kernel.

    Details:
    - Changed the declaration of k_iter and k_left for d, c, z microkernels
      from dim_t to uint64_t. This is needed to ensure compatibility with
      the movq instruction used to load the value into registers. This
      change should have been made a long time ago, but for some reason
      only recently began showing up via Travis CI.

    Fixed a memkind-related compile-time bug on knl.
    
    Details:
    - Fixed a compile-time error that occurred due to the fact that
      BLIS_ENABLE_MEMKIND, defined in bli_config.h, was not being defined
      soon enough to be used in bli_system.h where it is needed to determine
      whether hbwmalloc.h should be #included. bli_system.h is now included
      after bli_config.h (and bli_config_macro_defs.h). Thanks to Dave Love
      for reporting this issue.
    - Tweaked the language used by configure to echo the status of the
      --with[out]-memkind option.

    Removed vzeroupper intrinsics from zen kenels.
    
    Details:
    - Fixed a bug in the zen (also used by haswell) dotxf kernels whereby a
      vzeroupper instruction destoryed part of the intermediate result
      stored by the vdpps instructions that came right before. (The
      vzeroupper instrinsic was removed.)
    - Removed remaining vzeroupper instrinsics from other zen kernels.
      Previously, the vzeroupper instructions were included because BLIS is
      typically compiled with -mfpmath=sse. But it was brought to my
      attention that inserting these vzeroupper instructions is unnecessary
      for our purposes, since (a) -mfpmath=sse results in VEX-encoded scalar
      code rather than literal SSE instructions, and (b) compilers already
      (likely) insert vzeroupper instructions where necessary. Thanks to
      Devin Matthews for zeroing in on the dotxf bug.
    - Removed -malign-double from bulldozer make_defs.mk. This alignment
      was already happening by default since bulldozer is an x86_64 system.

    Added build system support for libmemkind.
    
    Details:
    - Added support for libmemkind to configure. configure attempts to
      detect the presence of libmemkind by compiling a small program
      containing #include <hbwmalloc.h> and a call to hbw_malloc(). If
      successful, it is assumed that libmemkind is present and available.
      If present, use of libmemkind is enabled by default, and otherwise
      use is disabled by default. If libmemkind is present, the user may
      explicitly disable use of the library by running configure with the
      --without-memkind option. Furthermore, a configuration may disable
      libmemkind, perhaps conditional on some aspect of the build system,
      by including -DBLIS_DISABLE_MEMKIND in the configuration's CPPROCFLAGS
      make variable and setting the BLIS_ENABLE_MEMKIND makefile variable,
      set in config.mk, to 'no'. (The knl configuration makes use of this
      latter feature; see below.)
    - If enabled at configure-time, bli_system.h will #include <hbwmalloc.h>
      and bli_kernel_macro_defs.h will define BLIS_MALLOC_POOL and
      BLIS_FREE_POOL to use hbw_malloc() and hbw_free(), respectively.
    - Deprecated explicit use of BLIS_NO_HBWMALLOC in
      config/knl/bli_family.knl.h and replaced use of -DBLIS_NO_HBWMALLOC in
      config/knl/make_defs.mk with -DBLIS_DISABLE_MEMKIND, which overrides
      (#undefs) the definition of BLIS_ENABLE_MEMKIND in bli_system.h, if it
      would otherwise be defined. Also, set the BLIS_ENABLE_MEMKIND makefile
      variable to 'no'.
    - common.mk now adds libmemkind to LDFLAGS if libmemkind is enabled.

    Updates to top-level and test driver Makefiles.
    
    Details:
    - Added logic to common.mk that will choose a BLIS library against which
      to link (LIBBLIS_LINK). The default choice is the static (.a) library;
      the shared (.so) library is chosen only if the shared library build was
      enabled and the static one was disabled.
    - Updated the various test driver Makefiles to reference this common,
      pre-chosen library against which to link. (Previously, these drivers
      unconditionally linked against the static library and would have
      failed if the static library build was disabled at configure-time.)
    - Renamed many of the variables in common.mk and the top-level Makefile
      so that variables relating to the libblis.[a|so] files, including
      paths to those files, begin with "LIBBLIS".
    - Shuffled around some of the library definitions from the top-level
      Makefile to common.mk.
    - Renamed BLIS_ENABLE_DYNAMIC_BUILD to BLIS_ENABLE_SHARED_BUILD, and
      the @enable_dynamic@ anchor to @enable_shared@ in build/config.mk.in
      and in configure.
    - A few other cleanups in the top-level Makefile.

    Details:
    - Added an 'input.operations.fast' file to testsuite directory to go
      along with the 'input.general.fast' file used by the 'make check'
      target in the top-level Makefile. This will allow the "fast" check
      to prune operations and/or parameter combinations from the test
      space in order to save time.
    - Currently, input.operations.fast prunes trmm3 and all transposition
      and conjugation parameters from the level-3 test space.
    - Reduced problem size tested in input.general.fast to 100 and disabled
      testing of 1m method.

    Integrated f2c'ed netlib BLAS test suite.
    
    Details:
    - Created a new test suite that exercises only the BLAS compatibility
      found in BLIS. The test suite is a straightforward port of code
      obtained from netlib LAPACK, run through f2c and linked to a stripped-
      down version of libf2c that is compiled along with the test drivers
      (to prevent any obvious ABI issues). The new BLAS test suite can be
      run from within its new local directory, 'blastest' (through its local
      'make ; make run' targets) or from the top-level Makefile (via the
      'make testblas' target). Output files are created in whatever directory
      the test drivers are run, whether it be the 'blastest' directory, the
      top-level source distribution directory, or the out-of-tree directory
      in which 'configure' was run. Also, the results of the BLAS test suite
      can be checked via 'make checkblas', which summarizes the presence or
      absence of test failures in a single line printed to stdout.
    - Updated the 'test' target to run both 'testblis' and 'testblas'.
    - Added a new 'testblis-fast' target that runs the BLIS testsuite with
      smaller problem sizes, allowing it to finish more quickly.
    - Added a 'make check' target, which runs 'checkblis-fast' and
      'checkblas'.
    - Changed .travis.yml so that Travis CI runs 'testblis-fast' instead of
      'testblis' before (calling the check-blistest.sh script to check the
      result manually).
    - Renamed some targets in the top-level Makefile to be consistent between
      BLAS and BLIS.

    Fixed a few obscure bugs in the BLAS API.
    
    Details:
    - Fixed a missing parameter in the definition of sdsdot_(). The 'sb'
      argument was missing. Strangely, the argument is omitted from dsdot_()
      in the BLAS API.
    - Fixed the missing 'c' or 'u' in the "?gerc" or "?geru" operation string
      passed to xerbla_() by the bla_ger_check() macro.
    - For bla_syrk_check() and bla_syr2k_check() macros, only allow
      conjugate-transpose (trans='c') as a valid argument for the real
      domain functions [sd]syrk_() and [sd]syr2k_(). (Previously, the
      argument was allowed even for the complex domain equivalents, which
      was inconsistent with the BLAS API.)

    Fixed cpp macro parameter "ch" typo in bla_ger.c.
    
    Details:
    - Previously, the BLAS routine-generating macro in bla_ger.c was
      incorrectly passing MKSTR(ch) into the _check() macro when it
      should have been passing in the char that was available, chxy.
      I've instead changed the name of the macro parameter from chxy
      to ch. Similar change as made to bla_ger.h for consistency.
      Thanks to Dave Love in helping track this down. (NOTE: This is
      actually the root cause of the bug that was first patched by
      increasing the length of the operation name strings passed into
      xerbla_(), as defined by the constant BLIS_MAX_BLAS_FUNC_STR_LENGTH,
      in 3d1a5a7. In theory, that change could be backed out now.)
    - Applied aforementioned chxy->ch change to bla_dot.[ch], as well as
      frame/compat/cblas/f77_sub/f77_dot_sub.[ch] (not because it needed
      to happen, but for naming consistency).
    - Reformatted function signatures/prototypes of CBLAS functions and
      function calls to BLAS in frame/compat/cblas/f77_sub/*.c.

    Convert op names to uppercase before calling xerbla_().
    
    Details:
    - Defined a new function, bli_string_mkupper(), that calls toupper() on
      every non-NULL character in a string.
    - Call bli_string_mkupper() prior to calling xerbla_() in the level-2/-3
      BLAS _check() macros. This prevents the BLAS testsuite from complaining
      that the operation name (e.g. "dgemm") does not match the expected
      value (e.g. "DGEMM"). Thanks to Dave Love for reporting this issue.

    Fixed printf() format overflow.
    
    Details:
    - Increased the length of operation name strings passed to xerbla_() in
      the level-2 and level-3 operation _check() functions, found in
      frame/compat/check. This avoids a format specifier overflow warning by
      gcc 7. Thanks to Dave Love for reporting this issue and suggesting the
      fix.

    Return after non-zero info in BLAS checks.
    
    Details:
    - Previously, when calling the BLAS compatibility layer, discovering a
      parameter check failure would result in the proper setting of the
      info parameter (printed by xerbla_()), but would also come with an
      immediate abort() rather than a return. This was incorrect behavior
      for two overlapping reasons.
      (1) BLAS should return gracefully to the caller in the event of a
          bad set of parameters, not abort().
      (2) When BLIS was being tested via the BLAS testsuite, BLIS's
          xerbla_() would correctly get preempted/overridden by the
          xerbla_() in the BLAS testsuite, but execution would then
          erroneously continue on to the BLIS implementation with bad
          parameter values.
    - The previous issue was addressed by disabling the abort() in BLIS's
      xerbla_(), changing all of the BLAS _check() functions to cpp macros,
      and adding a return statement to the end of each _check() macro's
      "if ( info != 0 )" conditional.
      Thanks to Dave Love for reporting this issue.

    Minor typo fix to printing arch in testsuite.
    
    Details:
    - Mistakenly was calling bli_cpuid_query_id() instead of
      bli_arch_query_id() in the recent addition to the testsuite output
      that prints the active sub-configuration. The former function is
      only used for multi-architecture builds, whereas the latter is the
      more general option that also works for single configuration
      (including 'configure auto') builds.

    Print sub-configuration name in testsuite output.
    
    Details:
    - Added a line to the testsuite output that prints the name of the
      current/active sub-configuration. This is useful when linking the
      testsuite against multi-configuration builds because it confirms
      the sub-configuration that is actually being employed at runtime.
      Thanks to Devin Matthews for suggesting this feature.

    Allow arbitrarily deep configuration families.
    
    Details:
    - Updated configure so that configuration families specified in the
      config_registry are no longer constrained as being only one level
      deep. For example, previously the x86_64 family could not be defined
      concisely in terms of, say, intel64 and amd64 families, and instead
      had to be defined as containing "haswell, sandybridge, penryn, zen,
      etc." In other words, families were constrained to only having
      singleton configurations as their members. That constraint is now
      lifted.
    - Redefined x86_64 family in config_registry in terms of intel64 and
      amd64.

    Updates to ARM hardware detection support.
    
    Details:
    - Updated/clarified the ARM preprocessor macro branch of bli_cpuid.c.
      Going forward, cortexa57 (64-bit), cortexa15, and cortexa9 (32-bit)
      sub-configurations are supported. However, the functions that detect
      features specific to a15 and a9 are identical, and since a15 is tested
      first, it will always be chosen for arm32 hardware (even if both
      sub-configurations were enabled at configure-time and the library is
      linked and run on an a9). Thus, more work needs to be done to
      distinguish these two.
    - Added cpp guard around x86_64 portions of bli_cpuid.c. Now, either
      the x86_64 or ARM code will be compiled (or neither, if neither
      environment is detected).
    - In bli_arch_query_id(), call bli_cpuid_query_id() when the
      BLIS_FAMILY_ARM64 or BLIS_FAMILY_ARM32 macros are defined.
    - Added arm64 and arm32 configuration families to config_registry.
    - Added a note to the arch_t typedef enum in bli_type_defs.h reminding
      the developer to update the string array in bli_arch.c whenever new
      enum values are added or existing values are reordered.

    Fixed missing flags during shared object build.
    
    Details:
    - Fixed a bug in common.mk that caused warning, position-independent
      code, miscellaneous, and general preprocessor flags to be omitted
      from the configuration family-specific variables that hold those
      values, as registered by the family's make_defs.mk file. This would
      most obviously manifest when targeting a configuration family such as
      'intel64' while simultaneously configuring for a shared object build,
      as the key '-fPIC' flag would be omitted at compile-time and prevent
      successful linking. Thanks to Dave Love for reporting this bug.
    - Other cleanups to common.mk for readability and clarity.

    Fixed cache blocksize bug in knl configuration.
    
    Details:
    - Changed the mc blocksize for double real execution in the knl sub-
      configuration from 160 to 148. The old value was not a multiple of
      mr (which is 24), and thus the safeguards in bli_gks_register_cntx()
      were tripping. Thanks for Dave Love for reporting this issue.
    - Switch knl sub-configuration to use default blocksizes for datatypes
      not supported by native kernels.
    - Fixed typos in bli_error.c that prevented certain error strings
      (which report maximum cache blocksizes not being multiples of their
      corresponding register blocksize) from properly initializing.

      easy to revert back to the previous combination of operation tests.
    - Added more comments to input.operations describing the use of
      individual "enable only" overrides.

    Use zen kernels in haswell sub-configuration.
    
    Details:
    - Register use of level-1v zen intrinsic kernels for amaxv, axpyv, dotv,
      dotxv, and scalv, as well asl level-1f zen intrinsic kernels for axpyf
      and dotxf. This works because these kernels simply target AVX/AVX2,
      and therefore work without modification on haswell hardware.
    - Switch to use of zen microkernels in bli_cntx_init_haswell.c. The zen
      kernels are essentially identical to those used by haswell, except that
      now zen kernels are a bit more up-to-date. In the future, I may
      continue to maintain duplicates, or I may keep the kernels named after
      one architecture (zen or haswell) but used by both sub-configurations.
    - In config_registry, enable use of both haswell and zen kernels for the
      haswell sub-configuration. This is necessary in order to make zen
      kernels visible when registering kernels in bli_cntx_init_haswell.c.
    - Enable use of assembly-based complex gemm microkernels for zen,
      bli_cgemm_zen_asm_3x8() and bli_zgemm_zen_asm_3x4(), in
      bli_cntx_init_zen.c. This was actually intended for 1681333.

      zen kernels (ie: other microtile shapes) which are not used by default.
      This was done mostly in case someone decided to pick up these kernels

      out-of-the-box.

    Fixed obscure read-beyond-bounds bug in sgemm ukrs.
    
    Details:
    - Fixed an obscure bug in the bli_sgemm_haswell_asm_6x16 and
      bli_sgemm_zen_asm_6x16 microkernels when the input/output matrix C
      is stored with general stride (ie: both rs and cs are non-unit). The
      bug was rooted in the way those microkernels read from matrix C--
      namely, they used vmovlps/vmovhps instead of movss. By loading two
      floats at a time, even if one of them was treated as junk, the
      assembly code could be written in a more concise manner. However,
      under certain conditions--if m % mr == 0 and n % nr == 0 and the
      underlying matrix is not an internal "view" into a larger matrix--
      this could result in the very last vmovhps of the last (bottom-right)
      microkernel invocation reading beyond valid memory. Specifically, the
      low 32 bits read would always be valid, but the high 32 bits could
      reside beyond the bounds of the array in which the output C matrix is
      contained. To remedy this situation, we now selectively use movss to
      load any element that could be the last element in the matrix.

      This affected bli_l1v_ker_prot.h, bli_l1f_ker_prot.h, and
      bli_l1m_ker_prot.h. (The 'restrict' was already being used to
      qualify cntx_t* arguments for kernels defined in bli_l3_ker_prot.h.)
    - Added comments to bli_l1v_ker.h, bli_l1f_ker.h, bli_l1m_ker.h, and
      bli_l3_ukr.h that help explain how those headers function to produce
      kernel prototypes using the prototype macros defined in the files
      mentioned above.

    Merge branch 'amd' into rt
    
    Details:
    - Merged contributions made by AMD via 'amd' branch (see summary below).
      Special thanks to AMD for their contributions to-date, especially with
      regard to intrinsic- and assembly-based kernels.
    - Added column storage output cases to microkernels in
      bli_gemm_zen_asm_d6x8.c and bli_gemmtrsm_l_zen_asm_d6x8.c. Even with
      the extra cost of transposing the microtile in registers, this is
      much faster than using the general storage case when the underlying
      matrix is column-stored.
    - Added s and d assembly-based zen gemmtrsm_u microkernel (including
      column storage optimization mentioned above).
    - Updated zen sub-configuration to reflect presence of new native
      kernels.
    - Temporarily reverted zen sub-configuration's level-3 cache blocksizes
      to smaller haswell values.
    - Temporarily disabled small matrix handling for zen configuration
      family in config/zen/bli_family_zen.h.
    - Updated zen CFLAGS according to changes in 1e4365b.
    - Updated haswell microkernels such that:
      - only one vzeroupper instruction is called prior to returning
      - movapd/movupd are used in leiu of movaps/movups for double-real
        microkernels. (Note that single-real microkernels still use
        movaps/movups.)
    - Added kernel prototypes to kernels/zen/bli_kernels_zen.h, which is
      now included via frame/include/bli_arch_config.h.
    - Minor updates to bli_amaxv_ref.c (and to inlined "test" implementation
      in testsuite/src/test_amaxv.c).
    - Added early return for alpha == 0 in bli_dotxv_ref.c.
    - Integrated changes from f07b176, including a fix for undefined
      behavior when executing the 1m method under certain conditions.
    - Updated config_registry; no longer need haswell kernels for zen
      sub-configuration.
    - Tweaked marginal and pass thresholds for dotxf.
    - Reformatted level-1v, -1f, and -3 amd kernels and inserted additional
      comments.
    - Updated LICENSE file to explicitly mention that parts are copyright
      UT-Austin and AMD.
    - Added AMD copyright to header templates in build/templates.
    
    Summary of previous changes from 'amd' branch.
    - Added s and d assembly-based zen gemm microkernels (d6x8 and d8x6) and
      s and d assembly-based zen gemmtrsm_l microkernels (d6x8).
    - Added s and d intrinsics-based zen kernels for amaxv, axpyv, dotv, dotxv,
      and scalv, with extra-unrolling variants for axpyv and scalv.
    - Added a small matrix handler to bli_gemm_front(), with the handler
      implemented in kernels/zen/3/bli_gemm_small_matrix.c.
    - Added additional logic to sumsqv that first attempts to compute the
      sum of the squares via dotv(). If there is a floating-point exception
      (FE_OVERFLOW), then the previous (numerically conservative) code is
      used; otherwise, the result of dotv() is square-rooted and stored as
      the result. This new implementation is only enabled when FE_OVERFLOW
      is #defined. If the macro is not #defined, then the previous
      implementation is used.
    - Added axpyv and dotv standalone test drivers to test directory.
    - Added zen support to old cpuid_x86.c driver in build/auto-detect/old.
    - Added thread-local and __attribute__-related macros to bli_macro_defs.h.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Thu Feb 15 18:36:54 2018 -0600

    Fixed an obscure bug in the 1m implementation.
    
    Details:
    - Fixed a bug in the way the bli_gemm1m_cntx_ref() function (defined in
      ref_kernels/bli_cntx_ref.c) initializes its context for 1m execution.
      Previously, the function probed the context that was in the process of
      being updated for use with 1m--this context being previously
      initialized/copied from a native context--for its storage preference
      to determine which "variant" (row- or column-oriented) of 1m would be
      needed. However, the _cntx_ref() function was not updating the method
      field of the context until AFTER this query, and the conditional which
      depended on it, had taken place, meaning the storage preference query
      function would mistakenly think the context was for native execution,
      since the context's method field would still be set to BLIS_NAT. This
      would lead it to incorrectly grab the storage preference of the complex
      domain microkernel rather than the corresponding real domain
      microkernel, which could cause the storage preference predicate to
      evaluate to the wrong value, which would lead to the _cntx_ref()
      function choosing the wrong variant. This could lead to undefined
      behavior at runtime. The method is now explicitly set within the
      context prior to calling the storage preference query function.
    - Updated comments in frame/ind/oapi/bli_l3_3m4m1m_oapi.c.
    - Fixed a typo in the commented-out CFLAGS in config/zen/make_defs.mk,
      which are appropriate for gcc 6.x and newer. (Mistakenly used
      -march=bdver4 instead of -march=znver1.)

    Document how to enable zen-specific instructions.
    
    Details:
    - Added as a comment in config/zen/make_defs.mk the list of compiler flags
      that could be added to manually enable the instructions provided by the
      Zen microarchitecture that are not already implied by -march=bdver4.
      This information, along with the previous commit's flags to selectively
      disable Bulldozer instructions no longer present in Zen, was gathered
      from [1]. I hesitate to enable use of these instructions since I don't
      have any Zen hardware to test on yet.

    Augment zen CFLAGS to prevent illegal instruction.
    
    Details:
    - Added various compiler flags (-mno-fma4 -mno-tbm -mno-xop -mno-lwp) so
      that compiling with -march=bdver4 on zen-based architectures does not
      result in an illegal instruction error at runtime. Note: This fix is
      only needed for gcc 5.4; gcc 6.3 or later supports the use of
      -march=znver1, which can be used in lieu of the augmented set of flags
      based on bdver4. Thanks to Nisanth Padinharepatt for reporting this
      error.

    - Print the name of the configuration in the output of the
      kernel-to-config map (and chosen pairs list) as a subtle way to remind
      the user that these only apply to the targeted configuration (whereas
      the config list and kernel list are printed without regard to which
      configuration was actually targeted).

    Intelligently select compiler for auto-detection.
    
    Details:
    - Rewrote code that selects the compiler for the purposes of compiling
      the auto-detection executable. CC (if specified) is tried first. Then
      gcc. Then clang. The absolute fallback is cc. The previous code was
      sort of broken, and seemed to unintentionally always use gcc.
    - Moved various configuration-agnostic flags from config/*/make_defs.mk
      files to common.mk. The new mechanism appends the configuration-
      agnostic flags to the various compiler flag variables initialized in
      make_defs.mk. Flags specific to the sub-configuration are still set
      in make_defs.mk.
    - Added -Wno-tautological-compare to CMISCFLAGS when clang is in use.
      Also added the flag to the compiler instantiation during configure-
      time hardware detection (when clang is selected).
    - Added some missing (but mostly-optional) quotes to configure script.

    Reimplemented configure-time hardware detection.
    
    Details:
    - Reimplemented the hardware detection functionality invoked when running
      "./configure auto". Previously, a standalone script in build/auto-detect
      that used CPUID was used. However, the script attempted to enumerate all
      models for each microarchitecture supported. The new approach recycles
      the same code used for runtime hardware detection introduced in 2c51356.
      This has two immediate benefits. First, it reduces and consolidates the
      code required to detect microarchitectures via the CPUID instruction.
      Second, it provides an indirect way of testing at configure-time the
      code that is used to detect hardware at runtime. This code is (a) only
      activated when targeting a configuration family (such as intel64 or
      amd64) at configure-time and (b) somewhat difficult to test in
      practice, since it relies on having access to older microarchitectures.
    - The above change required placing conditional cpp macro blocks in
      bli_arch.c and bli_cpuid.c which either #include "blis.h" or #include
      a bare-bones set of headers that does not rely on the presence of a
      bli_config.h header. This is needed because bli_config.h has not been
      created yet when configure-time auto-detection takes places.
    - Defined a new function in bli_arch.c, bli_arch_string(), which takes
      an arch_t id and returns a pointer to a string that contains the
      lowercase name of the corresponding microarchitecture. This function
      is used by the auto-detection script to printf() the name of the
      sub-configuration corresponding to the detected hardware.

    Added option to disable pack buffer memory pools.
    
    Details:
    - Added a new configure option, --[en|dis]able-packbuf-pools, which will
      enable or disable the use of internal memory pools for managing buffers
      used for packing. When disabled, the function specified by the cpp
      macro BLIS_MALLOC_POOL is called whenever a packing buffer is needed
      (and BLIS_FREE_POOL is called when the buffer is ready to be released,
      usually at the end of a loop). When enabled, which was the status quo
      prior to this commit, a memory pool data structure is created and
      managed to provide threads with packing buffers. The memory pool
      minimizes calls to bli_malloc_pool() (i.e., the wrapper that calls
      BLIS_MALLOC_POOL), but does so through a somewhat more complex
      mechanism that may incur additional overhead in some (but not all)
      situations. The new option defaults to --enable-packbuf-pools.
    - Removed the reinitialization of the memory pools from the level-3
      front-ends and replaced it with automatic reinitialization within the
      pool API's implementation. This required an extra argument to
      bli_pool_checkout_block() in the form of a requested size, but hides
      the complexity entirely from BLIS. And since bli_pool_checkout_block()
      is only ever called within a critical section, this change fixes a
      potential race condition in which threads using contexts with different
      cache blocksizes--most likely a heterogeneous environment--can check
      out pool blocks that are too small for the submatrices it wishes to
      pack. Thanks to Nisanth Padinharepatt for reporting this potential
      issue.
    - Removed several functions in light of the relocation of pool reinit,
      including bli_membrk_reinit_pools(), bli_memsys_reinit(),
      bli_pool_reinit_if(), and bli_check_requested_block_size_for_pool().
    - Updated the testsuite to print whether the memory pools are enabled or
      disabled.

    Modest performance boost to flatten-headers.py.
    
    Details:
    - Updated flatten-headers.py to pre-compile the main regular expression
      used to isolate #include directives and the header filenames they
      reference. The compiled regex object is then used over and over on
      each header file in the tree of referenced headers. This appears to
      have provided a 1.7-2x performance increase in the best case.
    - Other minor tweaks, such as renaming the main recursive function from
      replace_pass() to flatten_header().

      depending on the operating system, filesystem, etc. The python script
      abides by the same command line interface as its predecessor and
      targets python 2.7 or later. (Thanks to Devin Matthews for suggesting
      that I look into a python replacement for higher performance.)
    - Activated use of flatten-headers.py in common.mk via the FLATTEN_H
      variable.
    - Made minor tweaks to flatten-headers.sh such as spelling corrections
      in comments.

    Fixed testsuite Makefile brokenness from 9091a207.
    
    Details:
    - Fixed a makefile error encountered when building the testsuite directly
      in its directory (as opposed to indirectly via 'make test'). The fix
      involves introducing a new variable, BUILD_PATH, alongside the existing
      DIST_PATH variable. By default, BUILD_PATH is set to the current
      directory, and is overridden by other Makefiles used by, for example,
      the testsuite and standalone test drivers in testsuite or test,
      respectively.
    - Some files/directories in common.mk were redefined in terms of
      BUILD_DIR, such as the locations of config.mk file and the intermediate
      include directory.

    Details:
    - Defined the SHELL variable in common.mk as "/bin/bash" so that the
      -n option can be used with echo in the Makefile rule for flattening
      blis.h. Thanks to Devin Matthews for suggesting this fix.

    Simplified/fixed self-initialization.
    
    Details:
    - Fixed a race condition in self-initialization whereby the bli_is_init
      static variable could be erroneously read as TRUE by thread 1 while
      thread 0 is still executing bli_init_apis(), thus allowing thread 1 to
      use the library before it is actually ready. Thanks to to Minh Quan Ho
      and Devin Matthews for pointing out this issue.
    - Part of the solution to the aforementioned race condition was involved
      replacing the runtime initialization of the global scalar constants
      (e.g., BLIS_ONE, BLIS_ZERO, etc.) in bli_const.c with a static
      initialization of those same constants. This eliminates the need for
      bli_const_init() altogether. (The static initialization is made concise
      via preprocess macros.)
    - Defined bli_gks_query_cntx_noinit(), which behaves just like
      bli_gks_query_cntx(), except that it does not call bli_init_once(). This
      function is called in lieu of bli_gks_query_cntx() in bli_ind_init() and
      bli_memsys_init() so as to not result in any recursion into
      bli_init_once().
    - Removed BLIS_ONE_HALF, BLIS_MINUS_ONE_HALF global scalar constants.
      They have no use in BLIS or its test products, and we have little reason
      to believe they are used by others.
    - Removed testsuite/out file, which was accidentally committed as part
      of 70640a3.

    Added temp_dir argument to flatten-headers.sh.
    
    Details:
    - Added "temp_dir" argument to flatten-headers.sh so that the caller can
      specify where intermediate files should be created as the script runs.
    - Updated flatten-headers.sh to create intermediate files in temp_dir
      instead of alongside the corresponding source files. This should now
      (once again) allow out-of-tree builds where the BLIS distribution is
      read-only, or where the out-of-tree build is running concurrently with
      another out-of-tree build. (Thanks to Devin Matthews for pointing out
      the possibility of simultaneous out-of-tree builds.)

    Further attempt to fix out-of-tree builds.
    
    Details:
    - Fix applied in 87978f6 was necessary but not sufficient to fix
      out-of-tree builds. It turns out that using a source tree that had
      already built the target erroneously gave the impression that
      out-of-tree builds were working again, when in fact they were still
      broken. The additional changes in this commit should complete the
      fix that was started in the aforementioned commit. Thanks to Devin
      Matthews and Shaden Smith for their help in isolating this issue.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Mon Dec 11 17:18:43 2017 -0600

    Implemented library self-initialization.
    
    Details:
    - Defined two new functions in bli_init.c: bli_init_once() and
      bli_finalize_once(). Each is implemented with pthread_once(), which
      guarantees that, among the threads that pass in the same pthread_once_t
      data structure, exactly one thread will execute a user-defined function.
      (Thus, there is now a runtime dependency against libpthread even when
      multithreading is not enabled at configure-time.)
    - Added calls to bli_init_once() to top-level user APIs for all
      computational operations as well as many other functions in BLIS to
      all but guarantee that BLIS will self-initialize through the normal
      use of its functions.
    - Rewrote and simplified bli_init() and bli_finalize() and related
      functions.
    - Added -lpthread to LDFLAGS in common.mk.
    - Modified the bli_init_auto()/_finalize_auto() functions used by the
      BLAS compatibility layer to take and return no arguments. (The
      previous API that tracked whether BLIS was initialized, and then
      only finalized if it was initialized in the same function, was too
      cute by half and borderline useless because by default BLIS stays
      initialized when auto-initialized via the compatibility layer.)
    - Removed static variables that track initialization of the sub-APIs in
      bli_const.c, bli_error.c, bli_init.c, bli_memsys.c, bli_thread, and
      bli_ind.c. We don't need to track initialization at the sub-API level,
      especially now that BLIS can self-initialize.
    - Added a critical section around the changing of the error checking
      level in bli_error.c.
    - Deprecated bli_ind_oper_has_avail() as well as all functions
      bli_<opname>_ind_get_avail(), where <opname> is a level-3 operation
      name. These functions had no use cases within BLIS and likely none
      outside of BLIS.
    - Commented out calls to bli_init() and bli_finalize() in testsuite's
      main() function, and likewise for standalone test drivers in 'test'
      directory, so that self-initialization is exercised by default.

    Various typecasting fixes, mis-typed enums, etc.
    
    Details:
    - Fixed implicit typecasting of conj_t to trans_t in bli_[un]packm_cxk.c.
    - Properly typecast integer arguments to match format specifier in various
      calls to printf() in bli_l3_thrinfo.c, bli_cntx.c, bli_pool.c, and
      bli_util_oapi.c.
    - Fixed "unsigned less-than-comparison with zero" checks in bli_check.c,
      bli_cntx.h.
    - Fixed mis-typed enums in bli_cntx.c (e.g., l1mkr_t that should have been
      l1fkr_t or l1vkr_t).
    - Fixed instances of opid_t value BLIS_GEMM that should have been l3ukr_t
      value BLIS_GEMM_UKR in bli_cntx_ref.c.
    - NOTE: These issues were identified via compiler warnings when building

    Revert to default SIMD alignment for bulldozer.
    
    Details:
    - Removed the default-overriding #define of BLIS_SIMD_ALIGN_SIZE set in
      config/bulldozer/bli_kernel.h. Not sure where this value came from, but
      it would seem to allow for insufficient starting address alignment for

    Thread Safety: Move bli_init() before and bli_finalize() after main()
    
    BLIS provides APIs to initialize and finalize its global context.
    One application thread can finalize BLIS, while other threads
    in the application are stil using BLIS.
    
    This issue can be solved by removing bli_finalize() from API.
    One way to do this is by getting bli_finalize() to execute by default
    after application exits from main().
    
    GCC supports this behaviour with the help of __attribute__((destructor))
    added to the function that need to be executed after main exits.
    
    Similarly bli_init() can be made to run before application enters main()
    so that application need not call it.

    Thread safety: Make the global induced method status array local to thread
    
    BLIS retains a global status array for induced methods, and provides
    APIs to modify this state during runtime. So, one application thread
    can modify the state, before another starts the corresponding
    BLIS operation.
    
    This patch solves this issue by making the induced method status array
    local to threads.

    Fixed bugs in gemm/gemmtrsm ukr tests in testsuite.
    
    Details:
    - Fixed a bug in gemmtrsm test module that was due to improper partitioning
      into a k x k triangular matrix for the purposes of obtaining an mr x k
      micropanel of A with which to test.
    - Fixed a bug in gemm and gemmtrsm test modules that would only manifest for
      very large k (depending on the product of mr x kc on that architecture).
      The bug arose from the fact that the test module was triggering the
      allocation of blocks from the internal memory pools, which are limited in
      size. This allocation imposes an implicit assumption that the micro-
      panel being tested with will fit inside, and this assumption is violated
      for large values of k. Arbitrarily large k may now be tested for both
      operation tests.
    - Added OpenMP/pthread critical sections around the setting or getting of
      statuses from the induced method operation lookup table in bli_l3_ind.c.
    - Added the 'static' keyword to all pthread_mutex_t global variables in BLIS.
    - Thanks to Nisanth Padinharepatt of AMD for reporting the first and third
      issues.

    Moved 'family' field from cntx_t to cntl_t.
    
    Details:
    - Removed the family field inside the cntx_t struct and re-added it to the
      cntl_t struct. Updated all accessor functions/macros accordingly, as well
      as all consumers and intermediaries of the family parameter (such as
      bli_l3_thread_decorator(), bli_l3_direct(), and bli_l3_prune_*()). This
      change was motivated by the desire to keep the context limited, as much
      as possible, to information about the computing environment. (The family
      field, by contrast, is a descriptor about the operation being executed.)
    - Added additional functions to bli_blksz_*() API.
    - Added additional functions to bli_cntx_*() API.
    - Minor updates to bli_func.c, bli_mbool.c.
    - Removed 'obj' from bli_blksz_*() API names.
    - Removed 'obj' from bli_cntx_*() API names.
    - Removed 'obj' from bli_cntl_*(), bli_*_cntl_*() API names. Renamed routines
      that operate only on a single struct to contain the "_node" suffix to

    - Added enums for packm and unpackm kernels to bli_type_defs.h.

    Updated ar option list used by all configurations.
    
    Details:
    - Dropped 'u' from the list of modifiers passed into the library archiver
      ar. Previously, "cru" was used, while now we employ only "cr". This
      change was prompted by a warning observed on Ubuntu 16.04:
    
        ar: `u' modifier ignored since `D' is the default (see `U')
    
      This caused me to realize that the default mode causes timestamps to be
      zero, and thus the 'u' option, which causes only changed object files to
      be inserted, is not applicable.

    Added --force-version=STRING option to configure.
    
    Details:
    - Added an option to configure that allows the user to force an arbitrary
      version string at configure-time. The help text also now describes the
      usage information.
    - Changed the way the version string is communicated to the Makefile.
      Previously, it was read into the VERSION variable from the 'version' file
      via $(shell cat ...). Now, the VERSION variable is instead set in
      config.mk (via a configure-substituted anchor from config.mk.in).

    Updated openmp/pthread barriers with GNU atomics.
    
    Details:
    - Updated the non-tree openmp and pthreads barriers defined in
      bli_thrcomm_openmp.c and bli_thrcomm_pthreads.c to instead call a common
      implementation in bli_thrcomm.c, bli_thrcomm_barrier_atomic(). This new
      implementation goes through the same motions as the previous codes, but
      protects its loads and increments with GNU atomic built-ins. These atomic
      statements take memory ordering parameters that allow us to specify just
      enough constraints for the barrier to work as intended on weakly-ordered
      hardware. The prior implementation was only guaranteed to work on systems
      with strongly- ordered memory. (Thanks to Devin Matthews for suggesting
      this change and his crash-course in atomics and memory ordering.)
    - Removed 'volatile' from structs' barrier field declarations in
      bli_thrcomm_*.h.
    - Updated bli_thrcomm_pthread.? files to use renamed struct barrier fields
      consistent with that of the _openmp.? files.
    - Updated other bli_thrcomm_* files to rename "communicator" variables to
      simply "comm".

    Fixed a bug in norm1v, norm1m.
    
    Details:
    - Fixed a bug that manifested as improperly-computed 1-norm for vectors
      and matrices. This is one of the few operations in BLIS that does not
      have its own test module within the testsuite, hence why it went
      undetected for so long. The bad 1-norms were being used to normalize
      matrices in the testsuite after initialization, which led to some
      matrices containing a combination of "large" and "small" values. This
      tended to push the residuals computed after each test away from zero.
      In some cases, they were off *just* enough to the testsuite to label
      it a "failure". Many thanks to Jeff Hammond for reporting this bug.
      (Wonky details: the bug was due to improperly-defined level-0 scalar
      macros for abval2, an operation that computes the absolute square,
      or complex magnitude/modulus. Certain complex domain instances of
      abval2 were being incorrectly defined in terms of real-only solutions,
      leading to bad results. This level-0 operation forms the basis of
      norm1v/norm1m. absq2 was also affected, but almost nothing uses
      this operation.)

    we want to be able to run BLIS KNL binaries on non-KNL machines via SDE.
    although it is possible to install hbwmalloc implementation on such

    execution is not representative so there is no reason to emulate HBW
    allocation.

    Fixed a trsm1m bug that affected right-side cases.
    
    Details:
    - Fixed a bug introduced in 1c732d3 that affected trsm1m_r. The result
      was nondeterministic behavior (usually segmentation faults) for certain
      problem sizes beyond the 1m instance of kc (e.g. 128 on haswell). The
      cause of the bug was my commenting out lines in bli_gemm1m_ukr_ref.c
      which explicitly directed the virtual gemm micro-kernel to use temporary
      space if the storage preference of the [real domain] gemm ukernel did
      not match the storage of the output matrix C. In the context of gemm,
      this handling is not needed because agreement between the storage pref
      and the matrix is guaranteed by a high-level optimization in BLIS.
      However, this optimization is not applied to trsm because the storage
      of C is not necessarily the same as the storage of the micro-panels of
      B--both of which are updated by the micro-kernel during a trsm
      operation. Thus, the guarantee of storage/preference agreement is not
      in place for trsm, which means we must handle that case within the
      virtual gemm micro-kernel.
    - Comment updates and a minor macro change to bli_trsm*_cntx_init() for
      3m1, 4m1a, and 1m.

    Added 1m-specific APIs for bp, pb gemm algorithms.
    
    Details:
    - Defined bli_gemmbp_cntl_create(), bli_gemmpb_cntl_create(), with the
      body of bli_gemm_cntl_create() replaced with a call to the former.
    - Defined bli_cntl_free_w_thrinfo(), bli_cntl_free_wo_thrinfo(). Now,
      bli_cntl_free() can check if the thread parameter is NULL, and if so,
      call the latter, and otherwise call the former.
    - Defined bli_gemm1mbp_cntx_init(), bli_gemm1mpb_cntx_init(), both in
      terms of bli_gemm1mxx_cntx_init(), which behaves the same as
      bli_gemm1m_cntx_init() did before, except that an extra bool parameter
      (is_pb) is used to support both bp and pb algorithms (including to
      support the anti-preference field described below).
    - Added support for "anti-preference" in context. The anti_pref field,
      when true, will toggle the boolean return value of routines such as
      bli_cntx_l3_ukr_eff_prefers_storage_of(), which has the net effect of
      causing BLIS to transpose the operation to achieve disagreement (rather
      than agreement) between the storage of C and the micro-kernel output
      preference. This disagreement is needed for panel-block implementations,
      since they induce a transposition of the suboperation immediately before
      the macro-kernel is called, which changes the apparent storage of C. For
      now, anti-preference is used only with the pb algorithm for 1m (and not
      with any other non-1m implementation).
    - Defined new functions,
        bli_cntx_l3_ukr_eff_prefers_storage_of()
        bli_cntx_l3_ukr_eff_dislikes_storage_of()
        bli_cntx_l3_nat_ukr_eff_prefers_storage_of()
        bli_cntx_l3_nat_ukr_eff_dislikes_storage_of()
      which are identical to their non-"eff" (effectively) counterparts except
      that they take the anti-preference field of the context into account.
    - Explicitly initialize the anti-pref field to FALSE in
      bli_gks_cntx_set_l3_nat_ukr_prefs().
    - Added bli_gemm_ker_var1.c, which implements a panel-block macro-kernel
      in terms of the existing block-panel macro-kernel _ker_var2(). This
      technique requires inducing transposes on all operands and swapping
      the A and B.
    - Changed bli_obj_induce_trans() macro so that pack-related fields are
      also changed to reflect the induced transposition.
    - Added a temporary hack to bli_l3_3m4m1m_oapi.c that allows us to easily
      specify the 1m algorithm (block-panel or panel-block).
    - Renamed the following cntx_t-related macros:
        bli_cntx_get_pack_schema_a() -> bli_cntx_get_pack_schema_a_block()
        bli_cntx_get_pack_schema_b() -> bli_cntx_get_pack_schema_b_panel()
        bli_cntx_get_pack_schema_c() -> bli_cntx_get_pack_schema_c_panel()
      and updated all instantiations. Also updated the field names in the
      cntx_t struct.
    - Comment updates.

Author: Field G. Van Zee <field@cs.utexas.edu>

    Implemented the 1m method.
    
    Details:
    - Implemented the 1m method for inducing complex domain matrix
      multiplication. 1m support has been added to all level-3 operations,
      including trsm, and is now the default induced method when native
      complex domain gemm microkernels are omitted from the configuration.
    - Updated _cntx_init() operations to take a datatype parameter. This was
      needed for the corresponding function for 1m (because 1m requires us
      to choose between column-oriented or row-oriented execution, which
      requires us to query the context for the storage preference of the
      gemm microkernel, which requires knowing the datatype) but I decided
      that it made sense for consistency to add the parameter to all other
      cntx initialization functions as well, even though those functions
      don't use the parameter.
    - Updated bli_cntx_set_blkszs() and bli_gks_cntx_set_blkszs() to take
      a second scalar for each blocksize entry. The semantic meaning of the
      two scalars now is that the first will scale the default blocksize
      while the second will scale the maximum blocksize. This allows scaling
      the two independently, and was needed to support 1m, which requires
      scaling for a register blocksize but not the register storage
      blocksize (ie: "packdim") analogue.
    - Deprecated bli_blksz_reduce_dt_to() and defined two new functions,
      bli_blksz_reduce_def_to() and bli_blksz_reduce_max_to(), for reducing
      default and maximum blocksizes to some desired blocksize multiple.
      These functions are needed in the updated definitions of
      bli_cntx_set_blkszs() and bli_gks_cntx_set_blkszs().
    - Added support for the 1e and 1r packing schemas to packm, including
      1e/1r packing kernels.
    - Added a minor optimization to bli_gemm_ker_var2() that allows, under
      certain circumstances (specifically, real domain beta and row- or
      column-stored matrix C), the real domain macrokernel and microkernel
      to be called directly, rather than using the virtual microkernel
      via the complex domain macrokernel, which carries a slight additional
      amount of overhead.
    - Added 1m support to the testsuite.
    - Added 1m support to Makefile and runme.sh in test/3m4m. Also simplified
      some code in test_gemm.c driver.

    never use libm with Intel compilers
    
    Intel compilers include a highly optimized math library (libimf) that
    should be used instead of GNU libm.
    
    yes, this change is for ALL targets, including those that are not
    supported by the Intel compiler.  there is no harm in doing this, and it
    is future-proof in the event that the Intel compilers support other
    architectures.

    - Removed the vast majority of directories named "old", which contained
      deprecated code that I wasn't quite ready to jettison from the source
      tree.

    Modified bli_getopt() for thread-safety.
    
    Details:
    - Changed the interface of bli_getopt() to take a new argument, a getopt_t
      struct, that stores the values of optarg, optind, opterr, and optopt,
      and updated the implementation accordingly. (Previously,  these
      variables were assumed to be global.)
    - Added a function for initializing a getopt_t struct.
    - Changed test_libblis.c--currently the only consumer of bli_getopt()--to
      utilize the new getopt_t state object.

      static functions, including those in the following frame/base headers:
      auxinfo, cntl, mbool, mem, membrk, opid, and pool. A few headers in

      the caller or as returned from bli_arch_query_id()--against the expected
      range of id values. Thanks to Devangi Parikh for suggesting these

    Details:
    - Defined a new 'uninstall-old-headers' target that allows users of BLIS to
      uninstall no-longer-needed headers left over from previous installations.
    - Fixed the 'uninstall-old' target so that it will install both .a and .so
      libraries.
    - Renamed 'uninstall-old' to 'uninstall-old-libs'.
    - Added 'uninstall-old' target (different from previous 'uninstall-old'
      target) that combines 'uninstall-old-libs' and 'uninstall-old-headers'.

    Create/install monolithic cblas.h.
    
    Details:
    - When CBLAS is enabled at configure-time, BLIS now creates a monolithic
      cblas.h using the same flatten-header.sh script that was recently
      introduced for creating monolithic blis.h header files. The top-level
      Makefile will also install this cblas.h file into the install prefix
      alongside blis.h when the 'install' target is invoked. The two header
      files are compatible with one another. Regardless whether the user's
      source #includes cblas.h, both blis.h and cblas.h, or just blis.h,
      the user will get the CBLAS function prototypes and enums, as expected.

      function fails to return NULL when passed a kernel id argument that is
      equal to or beyond BLIS_NUM_[UN]PACKM_KERS. Instead, the function was

    Generate/compile with/install monolithic blis.h.
    
    Details:
    - Rewrote monolithify-header.sh (and renamed to flatten-header.sh) so that
      headers are inserted recursively. This improves performance by a factor
      of 3-4x.
    - Modified configure to create an 'include/<configname>' directory in which
      make can create a monolithic header.
    - Modified the top-level Makefile so that a monolithic header is generated
      unconditionally prior to compilation (stored in include/<configname>) and
      so that the single header is installed instead of the 450 or so header
      files that reside throughout the framework source tree.
    - Added "include/*/*.h" to .gitignore file.
    - Removed some pnacl/emscripten leftovers that I intended to include in
      a1caeba (mostly in testsuite/Makefile).
    - Trivial comment changes to frame/include/bli_f2c.h.

    Details:
    - Added support for the x86_64 configuration family to bli_arch.c and
      bli_arch_config.h. Thanks to Johannes Dieterich for reporting this
      issue.
    - Bumped the default value for BLIS_SIMD_NUM_REGISTERS from 16 to 32 and
      the default value for BLIS_SIMD_SIZE from 32 to 64. This will support
      configuration families that include Skylake and newer processors without
      any supported needed in the bli_family_*.h file. The semantics of these
      values have always been "maximum" and not exact values; comments in
      bli_kernel_macro_defs.h and the github wiki have been adjusted
      accordingly.

    Fixed a bug in e31f0b3/b131b9a.
    
    Details:
    - Erroneously placed the "don't overwrite existing blocksize" logic in
      bli_blksz_init*() rather than in bli_cntx_set_blkszs(). It belongs in
      the latter because that function copies blocksizes as-is from the
      blksz_t function argument to the appropriate field in the cntx_t. If
      the blksz_t was previously initialized selectively, based on the sign
      of the blocksize value passed into bli_blksz_init*(), that just leaves
      some fields possibly uninitialized (with garbage values), which
      definitely will not work.
    - The aforementioned logic has been moved to bli_cntx_set_blkszs() via
      a new function bli_blksz_copy_if_pos(), which selectively copies only
      the blocksizes that are greater than zero.

    Details:
    - Employ the new semantics of bli_blksz_init*() in e31f0b3 in various
      sub-configurations' bli_cntx_init_*() functions by passing in 0 for
      register and cache blocksizes that correpond to gemm microkernel
      datatypes that were not registered, allowing the default values
      set by the bli_cntx_init_*_ref() function call to remain.

    - Changed the vectorization flags for penryn to target the 'core2'
      microarchitecture and ssse3.

    Added travis_wait prefix to testsuite via Travis.
    
    Details:
    - It appears that Travis CL has implemented a new policy that results in
      a test failing if it does not produce any output for more than 10
      minutes. (Two test instances are now failing in Travis despite the most
      recent commit not affecting the library or testsuite.) This issue can
      be worked around by executing the test run via travis_wait, which takes
      an optional time parameter. This commit attempts to use 'travis_wait 30'
      in the .travis.yml file to prevent the early failure at 10 minutes.

    * Add x86 and x86_64 processor families.
    * Use generic config as fallback for more families.
    
    After discussion with fgvanzee, a) it's "generic" and 2) use it for all the families as a fallback. Goal is that if a specific CPU is not yet supported by a family (say a new Intel microarchitecture on x86_64), it'll fall through to still work with the slower "generic" kernels

    Details:
    - Added a new script, monolithify-header.sh, to the 'build' directory.
      This script recursively replaces all #include directives in a selected
      file with the contents of the header files referenced by each directive.
      The idea is to "flatten" a tree of .h files into a single file, with
      the script acting as a C preprocessor that only processes #include
      directives.

    Details:

      The generaly policy is that no header file in BLIS should include
      blis.h. This will be important in the near future when using a tool to
      recursively create a monolithic blis.h file from its consitutent
      headers.

    - Updated bli_cpuid_query_id() so that BLIS_ARCH_GENERIC is always returned
      if the hardware fails to test positive for any supported sub-configuration.
    - Defined bli_gks_init_ref_cntx(), which will call the context initialization
      function bli_cntx_init_configname() for the sub-configuration 'configname'
      associated with the arch_t id returned by bli_arch_query_id(). This makes
      initializing a reference context easy for experts who wish to construct
      those contexts.

    Implemented runtime hardware detection via cpuid.
    
    Details:
    - Added runtime support for selecting an appropriate arch_t value based
      on the results of the cpuid instruction (for x86_64). This allows
      deferral of choosing a context (kernels, blocksizes, etc.) until
      runtime, which allows BLIS to be built with support for multiple
      microarchitectures. Currently, only amd64 and intel64 configurations
      are registered in the config_registry; however, one could create
      custom configuration families to support arbitrary sets of x86_64
      microarchitectures.
    - Current Intel microarchitectures supported via cpuid are knl, haswell,
      sandybridge, and penryn.
    - Current AMD microarchitectures supported via cpuid are: zen, excavator,
      steamroller, piledriver, and bulldozer.

      config/bulldozer/bli_kernel.h. Not sure where this value came from, but
      it would seem to allow for insufficient starting address alignment for
      any matrices created via bli_malloc_user(), such as via
      bli_obj_create(). Thanks to Rene Sitt for reporting the behavior that
      led us to this bug.

    Use perl for some substitution for OS X compatibility.
    
    Details:
    - Discovered that sed commands where the replacement string contains '\n'
      are problematic with the version of sed present in OS X. For these cases
      cases in the configure script, we instead use 'perl -pe' for
      search-and-replace functionality.
    - Various other minor comment/whitespace tweaks to configure.
    - Removed remaining lines of code related to setting/checking variables to
      track "unregistered" configurations.

    Details:
    - Implemented a replacement for associative arrays in the configure script
      that does not utilize arrays, and therefore works in pre-4.0 versions of
      bash. (It appears that Mac OS X will be stuck with version 3.2 indefinitely
      due to bash switching to the GPL 3.0 license starting with version 4.0.)

    CLANG supports __attribute__, but its documentation doesn't
    mention support for constructor/destructor. Compiling with
    clang and testing shows that it does support this.

    - Added a "generic" configuration that leaves the default blocksizes and
      kernels unchanged. This replaces the older "reference" configuration.
      Updated auto-detect script and code accordingly.
    - Added support for generic configuration to arch_t (bli_type_defs.h),

      "bli_arch_config.h" and "bli_arch_config_pre.h", respectively.

    - Updated the top-level Makefile's build rule for testsuite object files to
      properly obtain CFLAGS via get-frame-cflags-for() function instead of
      simply using the $(CFLAGS) variable (which is empty). This means that
      'make test' should now work as expected.

      needs only set DIST_PATH to the relative path to the top level of the
      BLIS source distribution before including common.mk in order to acquire
      all of the definitions typically needed in a Makefile that tests BLIS.

    Implemented runtime kernel management.
    
    Details:
    - Reworked the build system around a configuration registry file, named
      config_registry', that identifies valid configuration targets, their
      constituent sub-configurations, and the kernel sets that are needed by
      those sub-configurations. The build system now facilitates the building
      of a single library that can contains kernels and cache/register
      blocksizes for multiple configurations (microarchitectures). Reference
      kernels are also built on a per-configuration basis.
    - Updated the Makefile to use new variables set by configure via the
      config.mk.in template, such as CONFIG_LIST, KERNEL_LIST, and KCONFIG_MAP,
      in determining which sub-configurations (CONFIG_LIST) and kernel sets
      (KERNEL_LIST) are included in the library, and which make_defs.mk files'
      CFLAGS (KCONFIG_MAP) are used when compiling kernels.
    - Reorganized 'kernels' directory into a "flat" structure. Renamed kernel
      functions into a standard format that includes the kernel set name
      (e.g. 'haswell'). Created a "bli_kernels_<kernelset>.h" file in each
      kernels sub-directory. These files exist to provide prototypes for the
      kernels present in those directories.
    - Reorganized reference kernels into a top-level 'ref_kernels' directory.
      This directory includes a new source file, bli_cntx_ref.c (compiled on
      a per-configuration basis), that defines the code needed to initialize
      a reference context and a context for induced methods for the
      microarchitecture in question.
    - Rewrote make_defs.mk files in each configuration so that the compiler
      variables (e.g. CFLAGS) are "stored" (renamed) on a per-configuration
      basis.
    - Modified bli_config.h.in template so that bli_config.h is generated with
      #defines for the config (family) name, the sub-configurations that are
      associated with the family, and the kernel sets needed by those
      sub-configurations.
    - Deprecated all kernel-related information in bli_kernel.h and transferred
      what remains to new header files named "bli_arch_<configname>.h", which
      are conditionally #included from a new header bli_arch.h. These files
      are still needed to set library-wide parameters such as custom
      malloc()/free() functions or SIMD alignment values.
    - Added bli_cntx_init_<configname>.c files to each configuration directory.
      The files contain a function, named the same as the file, that initializes
      a "native" context for a particular configuration (microarchitecture). The
      idea is that optimized kernels, if available, will be initialized into
      these contexts. Other fields will retain pointers to reference functions,
      which will be compiled on a per-configuration basis. These bli_cntx_init_*()
      functions will be called during the initialization of the global kernel
      structure. They are thought of as initializing for "native" execution, but
      they also form the basis for contexts that use induced methods. These
      functions are prototyped, along with their _ref() and _ind() brethren, by
      prototype-generating macros in bli_arch.h.
    - Added a new typedef enum in bli_type_defs.h to define an arch_t, which
      identifies the various sub-configurations.
    - Redesigned the global kernel structure (gks) around a 2D array of cntx_t
      structures (pointers to cntx_t, actually). The first dimension is indexed
      over arch_t and the inner dimension is the ind_t (induced method) for
      each microarchitecture. When a microarchitecture (configuration) is
      "registered" at init-time, the inner array for that configuration in the
      2D array is initialized (and allocated, if it hasn't been already). The
      cntx_t slot for BLIS_NAT is initialized immediately and those for other
      induced method types are initialized and cached on-demand, as needed. At
      cntx_t registration, we also store function pointers to cntx_init functions
      that will initialize (a) "reference" contexts and (b) contexts for use with
      induced methods. We don't cache the full contexts for reference contexts
      since they are rarely needed. The functions that initialize these two kinds
      of contexts are generated automatically for each targeted sub-configuration
      from cpp-templatized code at compile-time. Induced method contexts that
      need "stage" adjustments can still obtain them via functions in
      bli_cntx_ind_stage.c.
    - Added new functions and functionality to bli_cntx.c, such as for setting
      the level-1f, level-1v, and packm kernels, and for converting a native
      context into one for executing an induced method.
    - Moved the checking of register/cache blocksize consistency from being cpp
      macros in bli_kernel_macro_defs.h to being runtime checks defined in
      bli_check.c and called from bli_gks_register_cntx() at the time that the
      global kernel structure's internal context is initialized for a given
      microarchitecture/configuration.
    - Deprecated all of the old per-operation bli_*_cntx.c files and removed
      the previous operation-level cntx_t_init()/_finalize() invocations.
      Instead, we now query the gks for a suitable context, usually via
      bli_gks_query_cntx().
    - Deprecated support for the 3m2 and 3m3 induced methods. (They required
      hackery that I was no longer willing to support.)
    - Consolidated the 1e and 1r packm kernels for any given register blocksize
      into a single kernel that will branch on the schema and support packing
      to both formats.
    - Added the cntx_t* argument to all packm kernel signatures.
    - Deprecated the local function pointer array in all bli_packm_cxk*.c files
      and instead obtain the packm kernel from the cntx_t.
    - Added bli_calloc_intl(), which serves as the calloc-equivalent to to
      bli_malloc_intl(). Useful when we wish to allocate and initialize to
      zero/NULL.
    - Converted existing cpp macro functions defined in bli_blksz.h, bli_func.h,
      bli_cntx.h into static functions.

    Thread Safety: Move bli_init() before and bli_finalize() after main()
    
    BLIS provides APIs to initialize and finalize its global context.
    One application thread can finalize BLIS, while other threads
    in the application are stil using BLIS.
    
    This issue can be solved by removing bli_finalize() from API.
    One way to do this is by getting bli_finalize() to execute by default
    after application exits from main().
    
    GCC supports this behaviour with the help of __attribute__((destructor))
    added to the function that need to be executed after main exits.
    
    Similarly bli_init() can be made to run before application enters main()
    so that application need not call it.

    Thread safety: Make the global induced method status array local to thread
    
    BLIS retains a global status array for induced methods, and provides
    APIs to modify this state during runtime. So, one application thread
    can modify the state, before another starts the corresponding
    BLIS operation.
    
    This patch solves this issue by making the induced method status array
    local to threads.

    Fixed bugs in gemm/gemmtrsm ukr tests in testsuite.
    
    Details:
    - Fixed a bug in gemmtrsm test module that was due to improper partitioning
      into a k x k triangular matrix for the purposes of obtaining an mr x k
      micropanel of A with which to test.
    - Fixed a bug in gemm and gemmtrsm test modules that would only manifest for
      very large k (depending on the product of mr x kc on that architecture).
      The bug arose from the fact that the test module was triggering the
      allocation of blocks from the internal memory pools, which are limited in
      size. This allocation imposes an implicit assumption that the micro-
      panel being tested with will fit inside, and this assumption is violated
      for large values of k. Arbitrarily large k may now be tested for both
      operation tests.
    - Added OpenMP/pthread critical sections around the setting or getting of
      statuses from the induced method operation lookup table in bli_l3_ind.c.
    - Added the 'static' keyword to all pthread_mutex_t global variables in BLIS.
    - Thanks to Nisanth Padinharepatt of AMD for reporting the first and third
      issues.

      current use case within BLIS, but handling the situation is nonetheless
      prudent. Thanks to Minh Quan for reporting this issue and requesting
      the fix.

    Fixed a minor bug in level-3 packm management.
    
    Details:
    - Fixed a bug in bli_l3_packm() that caused cntl_t-cached packed mem_t
      entries to be released and then re-acquired unnecessarily. (In essence,
      the "<" operands in the conditional that guards the
      release-and-reacquire code block simply needed to be swapped.) The bug
      should have only affected performance (rather than the computed result).
      Thanks to Minh Quan for identifying and reporting the bug.

    Moved 'family' field from cntx_t to cntl_t.
    
    Details:
    - Removed the family field inside the cntx_t struct and re-added it to the
      cntl_t struct. Updated all accessor functions/macros accordingly, as well
      as all consumers and intermediaries of the family parameter (such as
      bli_l3_thread_decorator(), bli_l3_direct(), and bli_l3_prune_*()). This
      change was motivated by the desire to keep the context limited, as much
      as possible, to information about the computing environment. (The family
      field, by contrast, is a descriptor about the operation being executed.)
    - Added additional functions to bli_blksz_*() API.
    - Added additional functions to bli_cntx_*() API.
    - Minor updates to bli_func.c, bli_mbool.c.
    - Removed 'obj' from bli_blksz_*() API names.
    - Removed 'obj' from bli_cntx_*() API names.
    - Removed 'obj' from bli_cntl_*(), bli_*_cntl_*() API names. Renamed routines
      that operate only on a single struct to contain the "_node" suffix to
      differentiate with those routines that operate on the entire tree.
    - Added enums for packm and unpackm kernels to bli_type_defs.h.
    - Removed BLIS_1F and BLIS_VF from bszid_t definition in bli_type_defs.h.
      They weren't being used and probably never will be.

    Updated ar option list used by all configurations.
    
    Details:
    - Dropped 'u' from the list of modifiers passed into the library archiver
      ar. Previously, "cru" was used, while now we employ only "cr". This
      change was prompted by a warning observed on Ubuntu 16.04:
    
        ar: `u' modifier ignored since `D' is the default (see `U')
    
      This caused me to realize that the default mode causes timestamps to be
      zero, and thus the 'u' option, which causes only changed object files to
      be inserted, is not applicable.

    - Added an option to configure that allows the user to force an arbitrary
      version string at configure-time. The help text also now describes the
      usage information.
    - Changed the way the version string is communicated to the Makefile.
      Previously, it was read into the VERSION variable from the 'version' file
      via $(shell cat ...). Now, the VERSION variable is instead set in
      config.mk (via a configure-substituted anchor from config.mk.in).

    Updated openmp/pthread barriers with GNU atomics.
    
    Details:
    - Updated the non-tree openmp and pthreads barriers defined in
      bli_thrcomm_openmp.c and bli_thrcomm_pthreads.c to instead call a common
      implementation in bli_thrcomm.c, bli_thrcomm_barrier_atomic(). This new
      implementation goes through the same motions as the previous codes, but
      protects its loads and increments with GNU atomic built-ins. These atomic
      statements take memory ordering parameters that allow us to specify just
      enough constraints for the barrier to work as intended on weakly-ordered
      hardware. The prior implementation was only guaranteed to work on systems
      with strongly- ordered memory. (Thanks to Devin Matthews for suggesting
      this change and his crash-course in atomics and memory ordering.)
    - Removed 'volatile' from structs' barrier field declarations in
      bli_thrcomm_*.h.
    - Updated bli_thrcomm_pthread.? files to use renamed struct barrier fields
      consistent with that of the _openmp.? files.
    - Updated other bli_thrcomm_* files to rename "communicator" variables to
      simply "comm".

      pertaining to multithreading, such as BLIS_JC_NT or BLIS_NUM_THREADS.
    - Added the following convenience wrapper routines:

    Fixed a bug in norm1v, norm1m.
    
    Details:
    - Fixed a bug that manifested as improperly-computed 1-norm for vectors
      and matrices. This is one of the few operations in BLIS that does not
      have its own test module within the testsuite, hence why it went
      undetected for so long. The bad 1-norms were being used to normalize
      matrices in the testsuite after initialization, which led to some
      matrices containing a combination of "large" and "small" values. This
      tended to push the residuals computed after each test away from zero.
      In some cases, they were off *just* enough to the testsuite to label
      it a "failure". Many thanks to Jeff Hammond for reporting this bug.
      (Wonky details: the bug was due to improperly-defined level-0 scalar
      macros for abval2, an operation that computes the absolute square,
      or complex magnitude/modulus. Certain complex domain instances of
      abval2 were being incorrectly defined in terms of real-only solutions,
      leading to bad results. This level-0 operation forms the basis of

    Disable complex 3m/4m in testsuite by default.
    
    Details:
    - Disabled testsuite tests of all level-3 implementations based on 3m
      and 4m. This will improve testing runtime on Travis CI as well as for
      anyone manually running the testsuite using default test parameters.
      Thanks to Devin Matthews for suggesting this change.

    allow KNL build without hbwmalloc.h (i.e. emulated)
    
    we want to be able to run BLIS KNL binaries on non-KNL machines via SDE.
    although it is possible to install hbwmalloc implementation on such
    systems, it is easier not to, since obviously the performance of SDE
    execution is not representative so there is no reason to emulate HBW
    allocation.

    Fixed a trsm1m bug that affected right-side cases.
    
    Details:
    - Fixed a bug introduced in 1c732d3 that affected trsm1m_r. The result
      was nondeterministic behavior (usually segmentation faults) for certain
      problem sizes beyond the 1m instance of kc (e.g. 128 on haswell). The
      cause of the bug was my commenting out lines in bli_gemm1m_ukr_ref.c
      which explicitly directed the virtual gemm micro-kernel to use temporary
      space if the storage preference of the [real domain] gemm ukernel did
      not match the storage of the output matrix C. In the context of gemm,
      this handling is not needed because agreement between the storage pref
      and the matrix is guaranteed by a high-level optimization in BLIS.
      However, this optimization is not applied to trsm because the storage
      of C is not necessarily the same as the storage of the micro-panels of
      B--both of which are updated by the micro-kernel during a trsm
      operation. Thus, the guarantee of storage/preference agreement is not
      in place for trsm, which means we must handle that case within the
      virtual gemm micro-kernel.
    - Comment updates and a minor macro change to bli_trsm*_cntx_init() for
      3m1, 4m1a, and 1m.

    Added 1m-specific APIs for bp, pb gemm algorithms.
    
    Details:
    - Defined bli_gemmbp_cntl_create(), bli_gemmpb_cntl_create(), with the
      body of bli_gemm_cntl_create() replaced with a call to the former.
    - Defined bli_cntl_free_w_thrinfo(), bli_cntl_free_wo_thrinfo(). Now,
      bli_cntl_free() can check if the thread parameter is NULL, and if so,
      call the latter, and otherwise call the former.
    - Defined bli_gemm1mbp_cntx_init(), bli_gemm1mpb_cntx_init(), both in
      terms of bli_gemm1mxx_cntx_init(), which behaves the same as
      bli_gemm1m_cntx_init() did before, except that an extra bool parameter
      (is_pb) is used to support both bp and pb algorithms (including to
      support the anti-preference field described below).
    - Added support for "anti-preference" in context. The anti_pref field,
      when true, will toggle the boolean return value of routines such as
      bli_cntx_l3_ukr_eff_prefers_storage_of(), which has the net effect of
      causing BLIS to transpose the operation to achieve disagreement (rather
      than agreement) between the storage of C and the micro-kernel output
      preference. This disagreement is needed for panel-block implementations,
      since they induce a transposition of the suboperation immediately before
      the macro-kernel is called, which changes the apparent storage of C. For
      now, anti-preference is used only with the pb algorithm for 1m (and not
      with any other non-1m implementation).
    - Defined new functions,
        bli_cntx_l3_ukr_eff_prefers_storage_of()
        bli_cntx_l3_ukr_eff_dislikes_storage_of()
        bli_cntx_l3_nat_ukr_eff_prefers_storage_of()
        bli_cntx_l3_nat_ukr_eff_dislikes_storage_of()
      which are identical to their non-"eff" (effectively) counterparts except
      that they take the anti-preference field of the context into account.
    - Explicitly initialize the anti-pref field to FALSE in
      bli_gks_cntx_set_l3_nat_ukr_prefs().
    - Added bli_gemm_ker_var1.c, which implements a panel-block macro-kernel
      in terms of the existing block-panel macro-kernel _ker_var2(). This
      technique requires inducing transposes on all operands and swapping
      the A and B.
    - Changed bli_obj_induce_trans() macro so that pack-related fields are
      also changed to reflect the induced transposition.
    - Added a temporary hack to bli_l3_3m4m1m_oapi.c that allows us to easily
      specify the 1m algorithm (block-panel or panel-block).
    - Renamed the following cntx_t-related macros:
        bli_cntx_get_pack_schema_a() -> bli_cntx_get_pack_schema_a_block()
        bli_cntx_get_pack_schema_b() -> bli_cntx_get_pack_schema_b_panel()
        bli_cntx_get_pack_schema_c() -> bli_cntx_get_pack_schema_c_panel()
      and updated all instantiations. Also updated the field names in the
      cntx_t struct.
    - Comment updates.

    Implemented the 1m method.
    
    Details:
    - Implemented the 1m method for inducing complex domain matrix
      multiplication. 1m support has been added to all level-3 operations,
      including trsm, and is now the default induced method when native
      complex domain gemm microkernels are omitted from the configuration.
    - Updated _cntx_init() operations to take a datatype parameter. This was
      needed for the corresponding function for 1m (because 1m requires us
      to choose between column-oriented or row-oriented execution, which
      requires us to query the context for the storage preference of the
      gemm microkernel, which requires knowing the datatype) but I decided
      that it made sense for consistency to add the parameter to all other
      cntx initialization functions as well, even though those functions
      don't use the parameter.
    - Updated bli_cntx_set_blkszs() and bli_gks_cntx_set_blkszs() to take
      a second scalar for each blocksize entry. The semantic meaning of the
      two scalars now is that the first will scale the default blocksize
      while the second will scale the maximum blocksize. This allows scaling
      the two independently, and was needed to support 1m, which requires
      scaling for a register blocksize but not the register storage
      blocksize (ie: "packdim") analogue.
    - Deprecated bli_blksz_reduce_dt_to() and defined two new functions,
      bli_blksz_reduce_def_to() and bli_blksz_reduce_max_to(), for reducing
      default and maximum blocksizes to some desired blocksize multiple.
      These functions are needed in the updated definitions of
      bli_cntx_set_blkszs() and bli_gks_cntx_set_blkszs().
    - Added support for the 1e and 1r packing schemas to packm, including
      1e/1r packing kernels.
    - Added a minor optimization to bli_gemm_ker_var2() that allows, under
      certain circumstances (specifically, real domain beta and row- or
      column-stored matrix C), the real domain macrokernel and microkernel
      to be called directly, rather than using the virtual microkernel
      via the complex domain macrokernel, which carries a slight additional
      amount of overhead.
    - Added 1m support to the testsuite.
    - Added 1m support to Makefile and runme.sh in test/3m4m. Also simplified
      some code in test_gemm.c driver.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Wed Nov 23 17:59:06 2016 -0600

    Switched to simpler trsm_r implementation.
    
    Details:
    - Disabled the implementation of trsm_r that allows the right-hand matrix
      B to be trianglar, and switched to the implementation that simply
      transposes the operation (and thus the storage of C) in order to recast
      the operation as trsm_l. This avoids the need to use trsm_rl and trsm_ru
      macrokernels, which require an awkward swapping of MR and NR. For now,
      the support for trsm_r macrokernels, via separate control trees, remains.
    - Modified bli_config_macro_defs.h so that BLIS_RELAX_MCNR_NCMR_CONSTRAINTS
      is defined by default. This is mostly a safety precaution in case someone
      tries to switch back to the previous trsm_r implementation, but also
      serves as a convenience on some systems where one does not naturally
      choose blocksizes in a way that satisfies MC % NR = 0 and NC % MR = 0.

      broadcast-based implementations. (The previous microkernel file has been
      moved to an 'old' subdirectory.)

    Adjusted stride selection of ct in macrokernels.
    
    Details:
    - Updated the changes introduced in 618f433 so that the strides of the
      temporary microtile ct used in the macrokernels is determined based
      on the storage preference of the microkernel (via the new functions
      below), rather than the strides of c. In almost all cases, presently,
      this change results in no net effect, as a high-level optimization
      in the _front() functions aligns the storage of c to that of the
      microkernel's preference. However, I encountered some cases where
      this is not always the case in some development code that has yet
      to be committed, and therefore I'm generalizing the framework code
      in advance.
    - Defined two new functions in bli_cntx.c:
        bli_cntx_l3_ukr_prefers_rows_dt()
        bli_cntx_l3_ukr_prefers_cols_dt()
      which return bool_t's based on the current micro-kernel's storage
      preferences. For induced methods, the preference of the underlying
      real domain microkernel is returned.
    - Updated definition of bli_cntx_l3_ukr_dislikes_storage_of(), and
      by proxy bli_cntx_l3_ukr_prefers_storage_of(), to be in terms of
      the above functions, rather than querying the preferences of the
      native microkernel directly (which did the wrong thing for induced
      methods).

    Details:
    - Changed a cpp macro that was meant to prevent using certain trsm_r code
      if BLIS_RELAX_MCNR_NCMR_CONSTRAINTS was defined. It was actually coded
      incorrectly at first. I've now fixed its location and changed its
      consequence to a compile-time #error message.

    Can disable trsm_r-specific blocksize constraints.
    
    Details:
    - Added cpp guards around the constraints in bli_kernel_macro_defs.h
      that enforce MC % NR = 0 and NC % MR = 0. These constraints are ONLY
      needed when handling right-side trsm by allowing the matrix on the
      right (matrix B) to be triangular, because it involves swapping
      register, but not cache, blocksizes (packing A by NR and B by MR)
      and then swapping the operands to gemmtrsm just before that kernel
      is called. It may be useful to disable these constraints if, for
      example, the developer wishes to test the configuration with
      a different set of cache blocksizes where only MC % MR = 0 and
      NC % NR = 0 are enforced.
    - In summary, #defining BLIS_RELAX_MCNR_NCMR_CONSTRAINTS will bypass
      the enforcement of MC % NR = 0 and NC % MR = 0.

    Details:
    - Updated s and d microkernels in bli_gemm_asm_d8x6.c to relax alignment
      constraints.

      kernels in the d6x8 set.
    - This completes the d8x6 set (which may be used for situations when it
      is desirable to have a microkernel with a column preference).

    Align strides of ct in macrokernels to that of c.
    
    Details:
    - Previously, rs_ct and cs_ct, the strides of the temporary microtile used
      primarily in the macrokernels' edge case handling, were unconditionally
      set to 1 and MR, respectively. However, Devin Matthews noted that this
      ought to be changed so that the strides of ct were in agreement with the
      strides of C. (That is, if C was row-stored, then ct should be accessed
      as by rows as well.) The implicit assumption is that the strides of C
      have already been adjusted, via induced transposition, if the storage
      preference of the microkernel is at odds with the storage of C. So, if
      the microkernel prefers row storage, the macrokernel's interior cases
      would present row-stored (ideal) microkernel subproblems to the
      microkernel, but for edge cases, it would still see column-stored
      subproblems (not ideal). This commit fixes this issue. Thanks to Devin
      for his suggestion.

    yes, this change is for ALL targets, including those that are not

    is future-proof in the event that the Intel compilers support other
    architectures.

    Fixed multithreading compilation bug in 970745a.
    
    Details:
    - Moved the definition of the cpp macro BLIS_ENABLE_MULTITHREADING
      from bli_thread.h to bli_config_macro_defs.h. Also moved the
      sanity check that OpenMP and POSIX threads are not both enabled.
    - Thanks to Krzysztof Drewniak for reporting this bug.

    Removed auto-prototyping of malloc()/free() substitutes.
    
    Details:
    - Removed the header file, bli_malloc_prototypes.h, which automatically
      generated prototypes for the functions specified by the following
      cpp macros:
        BLIS_MALLOC_INTL
        BLIS_FREE_INTL
        BLIS_MALLOC_POOL
        BLIS_FREE_POOL
        BLIS_MALLOC_USER
        BLIS_FREE_USER
      These prototypes were originally provided primarily as a convenience
      to those developers who specified their own malloc()/free() substitutes
      for one or more of the following. However, we generated these prototypes
      regardless, even when the default values (malloc and free) of the
      macros above were used. A problem arose under certain circumstances
      (e.g., gcc in C++ mode on Linux with glibc) when including blis.h that
      stemmed from the "throw" specification which was added to the glibc's
      malloc() prototype, resulting in a prototype mismatch. Therefore, going
      forward, developers who specify their own custom malloc()/free()
      substitutes must also prototype those substitutes via bli_kernel.h.
      Thanks to Krzysztof Drewniak for reporting this bug, and Devin Matthews
      for researching the nature and potential solutions.

    - Moved #include of bli_malloc.h from blis.h to bli_type_defs.h.
    - Removed standalone mtx_t and mutex_t typedefs in bli_type_defs.h.
    - Moved #include of bli_mutex.h from bli_thread.h to bli_typedefs.h.
    - The redundant typedefs of membrk_t and mtx_t caused a warning on some C
      compilers. Thanks to Tyler Smith for reporting this issue.

      thread, for verification purposes or just to study the way thread
      information and communicators are used in BLIS.
    - Enabled some previously-disabled code in bli_l3_thrinfo.c for freeing
      an array of thrinfo_t* values that is used in the new, cpp-guarde code
      mentioned above.
    - Removed some old commented lines from bli_gemm_front.c.

      memory allocator that I was keeping around for no particular reason).

    Fixed bli_gemm() segfault on empty C matrices.
    
    Details:
    - Fixed a bug that would manifest in the form of a segmentation fault
      in bli_cntl_free() when calling any level-3 operation on an empty
      output matrix (ie: m = n = 0). Specifically, the code previously
      assumed that the entire control tree was built prior to it being
      freed. However, if the level-3 operation performs an early exit, the
      control tree will be incomplete, and this scenario is now handled.
      Thanks to Elmar Peise for reporting this bug.

      order to free the address immediately before the pointer. Thanks to Devin
      Matthews for reporting this bug.

    Reclassified amaxv operation as a level-1v kernel.
    
    Details:
    - Moved amaxv from being a utility operation to being a level-1v operation.
      This includes the establishment of a new amaxv kernel to live beside all
      of the other level-1v kernels.
    - Added two new functions to bli_part.c:
        bli_acquire_mij()
        bli_acquire_vi()
      The first acquires a scalar object for the (i,j) element of a matrix,
      and the second acquires a scalar object for the ith element of a vector.
    - Added integer support to bli_getsc level-0 operation. This involved
      adding integer support to the bli_*gets level-0 scalar macros.
    - Added a new test module to test amaxv as a level-1v operation. The test
      module works by comparing the value identified by bli_amaxv() to the
      the value found from a reference-like code local to the test module
      source file. In other words, it (intentionally) does not guarantee the
      same index is found; only the same value. This allows for different
      implementations in the case where a vector contains two or more elements
      containing exactly the same floating point value (or values, in the case
      of the complex domain).
    - Removed the directory frame/include/old/.

    Implemented distributed thrinfo_t management.
    
    Details:
    - Implemented Ricardo Magana's distributed thread info/communicator
      management. Rather that fully construct the thrinfo_t structures, from
      root to leaf, prior to spawning threads, the threads individually
      construct their thrinfo_t trees (or, chains), and do so incrementally,
      as needed, reusing the same structure nodes during subsequent blocked
      variant iterations. This required moving the initial creation of the
      thrinfo_t structure (now, the root nodes) from the _front() functions
      to the bli_l3_thread_decorator(). The incremental "growing" of the tree
      is performed in the internal back-end (ie: _int()) function, and so
      mostly invisible. Also, the incremental growth of the thrinfo_t tree is
      done as a function of the current and parent control tree nodes (as well
      as the parent thrinfo_t node), further reinforcing the parallel
      relationship between the two data structures.
    - Removed the "inner" communicator from thrinfo_t structure definition,
      as well as its id. Changed all APIs accordingly. Renamed
      bli_thrinfo_needs_free_comms() to bli_thrinfo_needs_free_comm().
    - Defined bli_l3_thrinfo_print_paths(), which prints the information
      in an array of thrinfo_t* structure pointers. (Used only as a
      debugging/verification tool.)
    - Deprecated the following thrinfo_t creation functions:
        bli_packm_thrinfo_create()
        bli_l3_thrinfo_create()
      because they are no longer used. bli_thrinfo_create() is now called
      directly when creating thrinfo_t nodes.

    Details:

      'openmp'. The previous expected string, 'omp', is still supported but
      should be considered deprecated.

    Avoid compiling BLAS/CBLAS files when disabled.
    
    Details:
    - Updated the top-level Makefile, build/config.mk.in template, and
      configure script so that object files corresponding to source files
      belonging to the BLAS compatibility layer are not compiled (or archived)
      when the compatibility layer is disabled. (Same for CBLAS.) Thanks
      to Devin Matthews for suggesting this optimization.
    - Slight change to the way configure handles internal variables. Instead
      of converting (overwriting) some, such as enable_blas2blis and
      enable_cblas, from a "yes" or "no" to a "1" or "0" value, the latter are
      now stored in new variables that live alongside the originals (with the
      suffix "_01").  This is convenient since some values need to be
      sed-substituted into the config.mk.in template, which requires "yes" or
      "no", while some need to be written to the bli_config.h.in template,
      which requires "0" or "1".

    Redesigned control tree infrastructure.
    
    Details:
    - Altered control tree node struct definitions so that all nodes have the
      same struct definition, whose primary fields consist of a blocksize id,
      a variant function pointer, a pointer to an optional parameter struct,
      and a pointer to a (single) sub-node. This unified control tree type is
      now named cntl_t.
    - Changed the way control tree nodes are connected, and what computation
      they represent, such that, for example, packing operations are now
      associated with nodes that are "inline" in the tree, rather than off-
      shoot braches. The original tree for the classic Goto gemm algorithm was
      expressed (roughly) as:
    
        blk_var2 -> blk_var3 -> blk_var1 -> ker_var2
                             |           |
                             -> packb    -> packa
    
      and now, the same tree would look like:
    
        blk_var2 -> blk_var3 -> packb -> blk_var1 -> packa -> ker_var2
    
      Specifically, the packb and packa nodes perform their respective packing
      operations and then recurse (without any loop) to a subproblem. This means
      there are now two kinds of level-3 control tree nodes: partitioning and
      non-partitioning. The blocked variants are members of the former, because
      they iteratively partition off submatrices and perform suboperations on
      those partitions, while the packing variants belong to the latter group.
      (This change has the effect of allowing greatly simplified initialization
      of the nodes, which previously involved setting many unused node fields to
      NULL.)
    - Changed the way thrinfo_t tree nodes are arranged to mirror the new
      connective structure of control trees. That is, packm nodes are no longer
      off-shoot branches of the main algorithmic nodes, but rather connected
      "inline".
    - Simplified control tree creation functions. Partitioning nodes are created
      concisely with just a few fields needing initialization. By contrast, the
      packing nodes require additional parameters, which are stored in a
      packm-specific struct that is tracked via the optional parameters pointer
      within the control tree struct. (This parameter struct must always begin
      with a uint64_t that contains the byte size of the struct. This allows
      us to use a generic function to recursively copy control trees.) gemm,
      herk, and trmm control tree creation continues to be consolidated into
      a single function, with the operation family being used to select
      among the parameter-agnostic macro-kernel wrappers. A single routine,
      bli_cntl_free(), is provided to free control trees recursively, whereby
      the chief thread within a groups release the blocks associated with
      mem_t entries back to the memory broker from which they were acquired.
    - Updated internal back-ends, e.g. bli_gemm_int(), to query and call the
      function pointer stored in the current control tree node (rather than
      index into a local function pointer array). Before being invoked, these
      function pointers are first cast to a gemm_voft (for gemm, herk, or trmm
      families) or trsm_voft (for trsm family) type, which is defined in
      frame/3/bli_l3_var_oft.h.
    - Retired herk and trmm internal back-ends, since all execution now flows
      through gemm or trsm blocked variants.
    - Merged forwards- and backwards-moving variants by querying the direction
      from routines as a function of the variant's matrix operands. gemm and
      herk always move forward, while trmm and trsm move in a direction that
      is dependent on which operand (a or b) is triangular.
    - Added functions bli_thread_get_range_mdim(), bli_thread_get_range_ndim(),
      each of which takes additional arguments and hides complexity in managing
      the difference between the way ranges are computed for the four families
      of operations.
    - Simplified level-3 blocked variants according to the above changes, so that
      the only steps taken are:
      1. Query partitioning direction (forwards or backwards).
      2. Prune unreferenced regions, if they exist.
      3. Determine the thread partitioning sub-ranges.
      <begin loop>
        4. Determine the partitioning blocksize (passing in the partitioning
           direction)
        5. Acquire the curren iteration's partitions for the matrices affected
           by the current variants's partitioning dimension (m, k, n).
        6. Call the subproblem.
      <end loop>
    - Instantiate control trees once per thread, per operation invocation.
      (This is a change from the previous regime in which control trees were
      treated as stateless objects, initialized with the library, and shared
      as read-only objects between threads.) This once-per-thread allocation
      is done primarily to allow threads to use the control tree as as place
      to cache certain data for use in subsequent loop iterations. Presently,
      the only application of this caching is a mem_t entry for the packing
      blocks checked out from the memory broker (allocator). If a non-NULL
      control tree is passed in by the (expert) user, then the tree is copied
      by each thread. This is done in bli_l3_thread_decorator(), in
      bli_thrcomm_*.c.
    - Added a new field to the context, and opid_t which tracks the "family"
      of the operation being executed. For example, gemm, hemm, and symm are
      all part of the gemm family, while herk, syrk, her2k, and syr2k are
      all part of the herk family. Knowing the operation's family is necessary
      when conditionally executing the internal (beta) scalar reset on on
      C in blocked variant 3, which is needed for gemm and herk families,
      but must not be performed for the trmm family (because beta has only
      been applied to the current row-panel of C after the first rank-kc
      iteration).
    - Reexpressed 3m3 induced method blocked variant in frame/3/gemm/ind
      to comform with the new control tree design, and renamed the macro-
      kernel codes corresponding to 3m2 and 4m1b.
    - Renamed bli_mem.c (and its APIs) to bli_memsys.c, and renamed/relocated
      bli_mem_macro_defs.h from frame/include to frame/base/bli_mem.h.
    - Renamed/relocated bli_auxinfo_macro_defs.h from frame/include to
      frame/base/bli_auxinfo.h.
    - Fixed a minor bug whereby the storage-to-ukr-preference matching
      optimization in the various level-3 front-ends was not being applied
      properly when the context indicated that execution would be via an
      induced method. (Before, we always checked the native micro-kernel
      corresponding to the datatype being executed, whereas now we check
      the native micro-kernel corresponding to the datatype's real projection,
      since that is the micro-kernel that is actually used by induced methods.
    - Added an option to the testsuite to skip the testing of native level-3
      complex implementations. Previously, it was always tested, provided that
      the c/z datatypes were enabled. However, some configurations use
      reference micro-kernels for complex datatypes, and testing these
      implementations can slow down the testsuite considerably.

    Avoid compiling BLAS/CBLAS files when disabled.
    
    Details:
    - Updated the top-level Makefile, build/config.mk.in template, and
      configure script so that object files corresponding to source files
      belonging to the BLAS compatibility layer are not compiled (or archived)
      when the compatibility layer is disabled. (Same for CBLAS.) Thanks
      to Devin Matthews for suggesting this optimization.
    - Slight change to the way configure handles internal variables. Instead
      of converting (overwriting) some, such as enable_blas2blis and
      enable_cblas, from a "yes" or "no" to a "1" or "0" value, the latter are
      now stored in new variables that live alongside the originals (with the
      suffix "_01").  This is convenient since some values need to be
      sed-substituted into the config.mk.in template, which requires "yes" or
      "no", while some need to be written to the bli_config.h.in template,
      which requires "0" or "1".

    Fixed bugs in bli_mutex_init() and friends.
    
    Details:
    - Fixed a couple of bugs that affected OpenMP and POSIX threads
      configurations that resulted in compiler errors and warnings due
      to type mismatch, and in the case of pthreads, a missing function
      argument. The bugs are fairly recent, introduced in a017062.

    Relax alignment restrictions for sandybridge ukrs.
    
    Details:
    - Relaxed the base pointer and leading dimension alignment restrictions
      in the sandybridge gemm microkernels, allowing the use of vmovups/vmovupd
      instead of vmovaps/vmovapd. These change mimic those made to the haswell
      microkernels in e0d2fa0 and ee2c139.
    - Updated testsuite modules as well as standalone test drivers in 'test'
      directory to use DBL_MAX as the initial time candidate. Thanks to Devin
      Matthews for suggesting this change.
    - Inserted #include "float.h" into bli_system.h (to gain access to DBL_MAX).
    - Minor update (vis-a-vis contexts) to driver code in test/3m4m.

    Integrated "memory broker" (membrk_t) abstraction.
    
    Details:
    - Integrated a patch originally authored and submitted by Ricardo Magana
      of HP Enterprise. The changeset inserts use of a new object type, membrk_t,
      (memory broker) that allows multiple sets of memory pools on, for example,
      separate NUMA nodes, each of which has a separate memory space.
    - Added membrk field to cntx_t and defined corresponding accessor macros.
    - Added membrk field to mem_t object and defined corresponding accessor macros.
    - Created new bli_membrk.c file, which contains the new memory broker API,
      including:
        bli_membrk_init(), bli_membrk_finalize()
        bli_membrk_acquire_[mv](), bli_membrk_release(),
        bli_membrk_init_pools(), bli_membrk_reinit_pools(),
        bli_membrk_finalize_pools(),
        bli_membrk_pool_size()
    - In bli_mem.c, changed function calls to
        bli_mem_init_pools()     -> bli_membrk_init()
        bli_mem_reinit_pools()   -> bli_membrk_reinit()
        bli_mem_finalize_pools() -> bli_membrk_finalize()
    - In bli_packv_init.c, bli_packm_init.c, changed function calls to:
        bli_mem_acquire_[mv]() -> bli_membrk_acquire_[mv]()
        bli_mem_release()      -> bli_membrk_release()
    - Added bli_mutex.c and related files to frame/thread. These files define
      abstract mutexes (locks) and corresponding APIs for pthreads, openmp, or
      single-threaded execution. This new API is employed within functions
      such as bli_membrk_acquire_[mv]() and bli_membrk_release().

    First phase of control tree redesign.
    
    Details:
    - These changes constitute the first set of changes in preparation to
      revamping the structure and use of control trees in BLIS. Modifications
      in this commit don't affect the control tree code yet, but rather lay
      the groundwork.
    - Defined wrappers for the following functions, where the the wrappers
      each take a direction parameter of a new enumerated type (BLIS_BWD or
      BLIS_FWD), dir_t, and executes the correct underlying function.
      - bli_acquire_mpart_*() and _vpart_*()
      - bli_*_determine_kc_[fb]()
      - bli_thread_get_range_*() and bli_thread_get_range_weighted_*()
    - Consolidated all 'f' (forwards-moving) and 'b' (backwards-moving)
      blocked variants for trmm and trsm, and renamed gemm and herk variants
      accordingly. The direction is now queried via routines such as
      bli_trmm_direct(), which deterines the direction from the implied side
      and uplo parameters. For gemm and herk, it is uncondtionally BLIS_FWD.
    - Defined wrappers to parameter-specific macrokernels for herk, trmm, and
      trsm, e.g. bli_trmm_xx_ker_var2(), that execute the correct underlying
      macrokernel based on the implied parameters. The same logic used to
      choose the dir_t in _direct() functions is used here.
    - Simplified the function pointer arrays in _int() functions given the
      consolidation and dir_t querying mentioned above.
    - Function signature (whitespace) reformatting for various functions.
    - Removed old code in various 'old' directories.

    Fixed compiler warning in rand[vm], randn[vm].
    
    Details:
    - Fixed compiler warnings about unused variables related to the disabling
      of normalization in the structured cases of the rand[vm] and randn[vm]
      operations.

commit a89555d1605574f3685813dcc972b636dd61264d
Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Fri Jun 17 14:08:35 2016 -0500

    Added randn[vm] operations, support in testsuite.
    
    Details:
    - Defined a new randomization operation, randn, on vectors and matrices.
      The randnv and randnm operations randomize each element of the target
      object with values from a narrow range of values. Presently, those
      values are all integer powers of two, but they do not need to be powers
      of two in order to achieve the primary goal, which is to initialize
      objects that can be operated on with plenty of precision "slack"
      available to allow computations that avoid roundoff. Using this method
      of randomization makes it much more likely that testsuite residuals of
      properly-functioning operations are close to zero, if not exactly zero.
    - Updated existing randomization operations randv and randm to skip
      special diagonal handling and normalization for matrices with structure.
      This is now handled by the testsuite modules by explicitly calling a
      testsuite function that loads the diagonal (and scales off-diagonal
      elements).
    - Added support for randnv and randnm in the testsuite with a new switch
      in input.general that universally toggles between use of the classic
      randv/randm, which use real values on the interval [-1,1], and
      randnv/randnm, which use only values from a narrow range. Currently,
      the narrow range is: +/-{2^0, 2^-1, 2^-2, 2^-3, 2^-4, 2^-5, 2^-6}, as
      well as 0.0.
    - Updated testsuite modules so that a testsutie wrapper function is called
      instead of directly calling the randomization operations (such as
      bli_randv() and bli_randm()). This wrapper also takes a bool_t that
      indicates whether the object's elements should be normalized. (NOTE: As
      alluded to above, in the test modules of triangular solve operations such
      as trsv and trsm, we perform the extra step of loading the diagonal.)
    - Defined a new level-0 operation, invertsc, which inverts a scalar.
    - Updated the abval2ris and sqrt2ris level-0 macros to avoid an unlikely
      but possible divide-by-zero.
    - Updated function signature and prototype formatting in testsuite.

    Reorganized code, APIs related to multithreading.
    
    Details:
    - Reorganized code and renamed files defining APIs related to multithreading.
      All code that is not specific to a particular operation is now located in a
      new directory: frame/thread. Code is now organized, roughly, by the
      namespace to which it belongs (see below).
    - Consolidated all operation-specific *_thrinfo_t object types into a single
      thrinfo_t object type. Operation-specific level-3 *_thrinfo_t APIs were
      also consolidated, leaving bli_l3_thrinfo_*() and bli_packm_thrinfo_*()
      functions (aside from a few general purpose bli_thrinfo_*() functions).
    - Renamed thread_comm_t object type to thrcomm_t.
    - Renamed many of the routines and functions (and macros) for multithreading.
      We now have the following API namespaces:
      - bli_thrinfo_*(): functions related to thrinfo_t objects
      - bli_thrcomm_*(): functions related to thrcomm_t objects.
      - bli_thread_*(): general-purpose functions, such as initialization,
        finalization, and computing ranges. (For now, some macros, such as
        bli_thread_[io]broadcast() and bli_thread_[io]barrier() use the
        bli_thread_ namespace prefix, even though bli_thrinfo_ may be more
        appropriate.)
    - Renamed thread-related macros so that they use a bli_ prefix.
    - Renamed control tree-related macros so that they use a bli_ prefix (to be
      consistent with the thread-related macros that were also renamed).
    - Removed #undef BLIS_SIMD_ALIGN_SIZE from dunnington's bli_kernel.h. This
      #undef was a temporary fix to some macro defaults which were being applied
      in the wrong order, which was recently fixed.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Tue May 24 13:15:32 2016 -0500

    Implemented developer-configurable malloc()/free().
    
    Details:
    - Replaced all instances of bli_malloc() and bli_free() with one of:
      - bli_malloc_pool()/bli_free_pool()
      - bli_malloc_user()/bli_free_user()
      - bli_malloc_intl()/bli_free_intl()
      each of which can be configured to call malloc()/free() substitutes,
      so long as the substitute functions have the same function type
      signatures as malloc() and free() defined by C's stdlib.h. The _pool()
      function is called when allocating blocks for the memory pools (used
      for packing buffers, primarily), the _user() function is called when
      obj_t's are created (via bli_obj_create() and friends), and the _intl()
      function is called for internal use by BLIS, such as when creating
      control tree nodes or temporary buffers for manipulating internal data
      structures. Substitutes for any of the three types of bli_malloc() may
      be specified by #defining the following pairs of cpp macros in
      bli_kernel.h:
      - BLIS_MALLOC_POOL/BLIS_FREE_POOL
      - BLIS_MALLOC_USER/BLIS_FREE_USER
      - BLIS_MALLOC_INTL/BLIS_FREE_INTL
      to be the name of the substitute functions. (Obviously, the object
      code that contains these functions must be provided at link-time.)
      These macros default to malloc() and free(). Subsitute functions are
      also automatically prototyped by BLIS (in bli_malloc_prototypes.h).
    - Removed definitions for bli_malloc() and bli_free().
    - Note that bli_malloc_pool() and bli_malloc_user() are now defined in
      terms of a new function, bli_malloc_align(), which aligns memory to an
      arbitrary (power of two) alignment boundary, but does so manually,
      whereas before alignment was performed behind the scenes by
      posix_memalign(). Currently, bli_malloc_intl() is defined in terms
      of bli_malloc_noalign(), which serves as a simple wrapper to the
      designated function that is passed in (e.g. BLIS_MALLOC_INTL).
      Similarly, there are bli_free_align() and bli_free_noalign(), which
      are used in concert with their bli_malloc_*() counterparts.

    Added alignment switch to testsuite.
    
    Details:
    - Added a new input parameter to input.general that globally toggles
      whether testsuite tests are performed on objects whose buffers and
      leading dimensions have been aligned, and changed the implementation
      of libblis_test_mobj_create() to employ alignment (or not) regardless
      of whether row, column, or general storage is being tested.
    - Updated configure script's "--help" text to indicate default behavior
      for internal integer type size and BLAS/CBLAS integer type size
      options.

    Generate prototypes for user-defined packm kernels.
    
    Details:
    - Created template prototypes for packm kernels (in bli_l1m_ker.h), and
      then redefined reference packm kernels' prototyping headers in terms of
      this template, as is already done for level-1v, -1f, and -3 kernels.
    - Automatically generate prototypes for user-defined packm kernels in
      bli_kernel_prototypes.h (using the new template prototypes in
      bli_l1m_ker.h).
    - Defined packm kernel function types in bli_l1m_ft.h, including for
      packm kernels specific to induced methods, which are now used in
      bli_packm_cxk.c and friends rather than using a locally-defined
      function type.
    - In bli_packm_cxk.c, extended function pointer for packm kernels array
      from out to index 31 (from previous maximum of 17). This allows us to
      store the unrolled 30xk kernel in the array for use (on knc, for
      example). Note: This should have been done a long time ago.

    Details:
    - Fixed incorrect calls to bli_get_range_*() from within trsm blocked
      variants 1f, 2b, and 2f. The bug somehow went undetected since the
      big commit (537a1f4), and, strangely, did not manifest via the BLIS
      testsuite. The bug finally came to our attention when running thei
      libflame test suite while linking to BLIS. Thanks to Kiran Varaganti
      for submitting the initial report that led to this bug.

    Details:
    - Fixed a typo in bli_l1f_ref.h, introduced into bbb8569, that only
      manifested when non-reference level-1f kernels were used.
    - Added an #undef BLIS_SIMD_ALIGN_SIZE to bli_kernel.h of dunnington
      configuration to prevent a compile-time warning until I can figure out
      the proper permanent fix.
    - Moved frame/1f/kernels/bli_dotxaxpyf_ref_var1.c out of the compilation
      path (into 'other' directory). _ref_var2 is used by default, which is
      the variant that is built on axpyf and dotxf instead of dotaxpyv.
    - Removed section of frame/include/bli_config_macro_defs.h pertaining to
      mixed datatype support.

    Use 'restrict' in all kernel APIs; wspace changes.
    
    Details:
    - Updated level-1v, level-1f kernel function types (bli_l1?_ft.h) and
      generic kernel prototypes (bli_l1?_ker.h) to use 'restrict' for all
      numerical operand pointers (ie: all pointers except the cntx_t).
    - Updated level-1f reference kernel definitions to use 'restrict' for
      all numerical operand pointers. (Level-1v reference kernel definitions
      were already updated in bdbda6e.)
    - Rewrote the level-1v and level-1f reference kernel prototypes in
      bli_l1v_ref.h and bli_l1f_ref.h, respectively, to simply #include
      bli_l1v_ker.h and bli_l1f_ker.h with redefined function base names
      (as was already being done for the level-3 micro-kernel prototypes
      in bli_l3_ref.h), rather than duplicate the signatures from the
      _ker.h files.
    - Added definitions to frame/include/bli_kernel_prototypes.h for axpbyv
      and xpbyv, which were probably meant for inclusion in bdbda6e.
    - Converted a number of instances of four spaces, as introduced in
      bdbda6e, to tabs.

    Additionally, configure options which require defining macros (the above plus the threading model), write their macros to the automatically-generated bli_config.h file in the top-level build directory. The old bli_config.h files in the config dirs were removed, and any kernel-related macros (SIMD size and alignment etc.) were moved to bli_kernel.h. The Makefiles were also modified to find the new bli_config.h file.
    
    Lastly, support for OMP in clang has been added (closes #56).

    Compile-time fix to bgq l1f kernels.
    
    Details:
    - Fixed an old reference to bli_daxpyf_fusefac, which no longer exists,
      by replacing it with the axpyf fusing factor (8), and cleaned up the
      relevant section of config/bgq/bli_kernel.h.
    - Removed most of the details of the level-3 kernels from the template
      kernel code in config/template/kernels/3 and replaced it with a
      reference to the relevant kernel wiki maintained on the BLIS github
      website.

    Use kernel CFLAGS on "ukernels" directories.
    
    Details:
    - Updated the top-level Makefile so that the CFLAGS variable designated
      for kernel source code is applied not only to source code in
      directories named "kernels" but source code in any directory that
      contains the substring "kernels", such as "ukernels".
    - Formally disabled some code in gen-make-frag.sh script that was already
      effectively disabled. The code was related to handling "noopt" and
      "kernel" directories, which is now handled independently within the
      top-level Makefile without needing to place these source files into
      a spearate makefile variable.

    Implemented runtime contexts and reorganized code.
    
    Details:
    - Retrofitted a new data structure, known as a context, into virtually
      all internal APIs for computational operations in BLIS. The structure
      is now present within the type-aware APIs, as well as many supporting
      utility functions that require information stored in the context. User-
      level object APIs were unaffected and continue to be "context-free,"
      however, these APIs were duplicated/mirrored so that "context-aware"
      APIs now also exist, differentiated with an "_ex" suffix (for "expert").
      These new context-aware object APIs (along with the lower-level, type-
      aware, BLAS-like APIs) contain the the address of a context as a last
      parameter, after all other operands. Contexts, or specifically, cntx_t
      object pointers, are passed all the way down the function stack into
      the kernels and allow the code at any level to query information about
      the runtime, such as kernel addresses and blocksizes, in a thread-
      friendly manner--that is, one that allows thread-safety, even if the
      original source of the information stored in the context changes at
      run-time; see next bullet for more on this "original source" of info).
      (Special thanks go to Lee Killough for suggesting the use of this kind
      of data structure in discussions that transpired during the early
      planning stages of BLIS, and also for suggesting such a perfectly
      appropriate name.)
    - Added a new API, in frame/base/bli_gks.c, to define a "global kernel
      structure" (gks). This data structure and API will allow the caller to
      initialize a context with the kernel addresses, blocksizes, and other
      information associated with the currently active kernel configuration.
      The currently active kernel configuration within the gks cannot be
      changed (for now), and is initialized with the traditional cpp macros
      that define kernel function names, blocksizes, and the like. However,
      in the future, the gks API will be expanded to allow runtime management
      of kernels and runtime parameters. The most obvious application of this
      new infrastructure is the runtime detection of hardware (and the
      implied selection of appropriate kernels). With contexts in place,
      kernels may even be "hot swapped" at runtime within the gks. Once
      execution enters a level-3 _front() function, the memory allocator will
      be reinitialized on-the-fly, if necessary, to accommodate the new
      kernels' blocksizes. If another application thread is executing with
      another (previously loaded) kernel, it will finish in a deterministic
      fashion because its kernel information was loaded into its context
      before computation began, and also because the blocks it checked out
      from the internal memory pools will be unaffected by the newer threads'
      reinitialization of the allocator.
    - Reorganized and streamlined the 'ind' directory, which contains much of
      the code enabling use of induced methods for complex domain matrix
      multiplication; deprecated bli_bsv_query.c and bli_ukr_query.c, as
      those APIs' functionality is now mostly subsumed within the global
      kernel structure.
    - Updated bli_pool.c to define a new function, bli_pool_reinit_if(),
      that will reinitialize a memory pool if the necessary pool block size
      has increased.
    - Updated bli_mem.c to use bli_pool_reinit_if() instead of
      bli_pool_reinit() in the definition of bli_mem_pool_init(), and placed
      usage of contexts where appropriate to communicate cache and register
      blocksizes to bli_mem_compute_pool_block_sizes().
    - Simplified control trees now that much of the information resides in
      the context and/or the global kernel structure:
      - Removed blocksize object pointers (blksz_t*) fields from all control
        tree node definitions and replaced them with blocksize id (bszid_t)
        values instead, which may be passed into a context query routine in
        order to extract the corresponding blocksize from the given context.
      - Removed micro-kernel function pointers (func_t*) fields from all
        control tree node definitions. Now, any code that needs these function
        pointers can query them from the local context, as identified by a
        level-3 micro-kernel id (l3ukr_t), level-1f kernel id, (l1fkr_t), or
        level-1v kernel id (l1vkr_t).
      - Removed blksz_t object creation and initialization, as well as kernel
        function object creation and initialization, from all operation-
        specific control tree initialization files (bli_*_cntl.c), since this
        information will now live in the gks and, secondarily, in the context.
    - Removed blocksize multiples from blksz_t objects. Now, we track
      blocksize multiples for each blocksize id (bszid_t) in the context
      object.
    - Removed the bool_t's that were required when a func_t was initialized.
      These bools are meant to allow one to track the micro-kernel's storage
      preferences (by rows or columns). This preference is now tracked
      separately within the gks and contexts.
    - Merged and reorganized many separate-but-related functions into single
      files. This reorganization affects frame/0, 1, 1d, 1m, 1f, 2, 3, and
      util directories, but has the most obvious effect of allowing BLIS
      to compile noticeably faster.
    - Reorganized execution paths for level-1v, -1d, -1m, and -2 operations
      in an attempt to reduce overhead for memory-bound operations. This
      includes removal of default use of object-based variants for level-2
      operations. Now, by default, level-2 operations will directly call a
      low-level (non-object based) loop over a level-1v or -1f kernel.
    - Converted many common query functions in blk_blksz.c (renamed from
      bli_blocksize.c) and bli_func.c into cpp macros, now defined in their
      respective header files.
    - Defined bli_mbool.c API to create and query "multi-bools", or
      heterogeneous bool_t's (one for each floating-point datatype), in the
      same spirit as blksz_t and func_t.
    - Introduced two key parameters of the hardware: BLIS_SIMD_NUM_REGISTERS
      and BLIS_SIMD_SIZE. These values are needed in order to compute a third
      new parameter, which may be set indirectly via the aforementioned
      macros or directly: BLIS_STACK_BUF_MAX_SIZE. This value is used to
      statically allocate memory in macro-kernels and the induced methods'
      virtual kernels to be used as temporary space to hold a single
      micro-tile. These values are now output by the testsuite. The default
      value of BLIS_STACK_BUF_MAX_SIZE is computed as
      "2 * BLIS_SIMD_NUM_REGISTERS * BLIS_SIMD_SIZE".
    - Cleaned up top-level 'kernels' directory (for example, renaming the
      embarrassingly misleading "avx" and "avx2" directories to "sandybridge"
      and "haswell," respectively, and gave more consistent and meaningful
      names to many kernel files (as well as updating their interfaces to
      conform to the new context-aware kernel APIs).
    - Updated the testsuite to query blocksizes from a locally-initialized
      context for test modules that need those values: axpyf, dotxf,
      dotxaxpyf, gemm_ukr, gemmtrsm_ukr, and trsm_ukr.
    - Reformatted many function signatures into a standard format that will
      more easily facilitate future API-wide changes.
    - Updated many "mxn" level-0 macros (ie: those used to inline double loops
      for level-1m-like operations on small matrices) in frame/include/level0
      to use more obscure local variable names in an effort to avoid variable
      shaddowing. (Thanks to Devin Matthews for pointing these gcc warnings,
      which are only output using -Wshadow.)
    - Added a conj argument to setm, so that its interface now mirrors that
      of scalm. The semantic meaning of the conj argument is to optionally
      allow implicit conjugation of the scalar prior to being populated into
      the object.
    - Deprecated all type-aware mixed domain and mixed precision APIs. Note
      that this does not preclude supporting mixed types via the object APIs,
      where it produces absolutely zero API code bloat.

    Included missing blas2blis integer def to CBLAS.
    
    Details:
    - Added #include "bli_config_macro_defs" to all cblas_*.c files in
      compat/cblas/src. This has the effect of defining
      BLIS_BLAS2BLIS_INT_TYPE_SIZE to the default value if bli_config.h does
      not define it. Thanks to Tony Kelman for reporting this bug.
    - In cblas_i?amax.c, changed the type of the variable 'iamax' from 'int'
      to 'f77_int'. This eliminates a compiler warning and a potential
      runtime bug and/or crash when the size of an int differs from the size
      of f77_int (as determined by BLIS_BLAS2BLIS_INT_TYPE_SIZE).

    Minor changes to treatment of rs, cs in bli_obj.c.
    
    Details:
    - Applied a patch submitted by Devin Matthews that:
      - implements subtle changes to handling of somewhat unusual cases of
        row and column strides to accommodate certail tensor cases, which
        includes adding dimension parameters to _is_col_tilted() and
        _is_row_tilted() macros,
      - simplifies how buffers are sized when requested BLIS-allocated
        objects,
      - re-consolidates bli_adjust_strides_*() into one function, and
      - defines 'restrict' keyword as a "nothing" macro for C++ and pre-C99
        environments.

    Fixed unimplemented case in core2 sgemm ukernel.
    
    Details:
    - Implemented the "beta == 0" case for general stride output for the
      dunnington sgemm micro-kernel. This case had been, up until now,
      identical to the "beta != 0" case, which does not work when the
      output matrix has nan's and inf's. It had manifested as nan residuals
      in the test suite for right-side tests of ctrsm4m1a. Thanks to Devin
      Matthews for reporting this bug.

    Fixed minor bugs for uncommon obj_create cases.
    
    Details:
    - Separated bli_adjust_strides() into _alloc() and _attach() flavors so
      that the latter can avoid a test performed by the former, in which the
      rs and cs are overridden and set to zero if either matrix dimension is
      zero. Actually, we also disable this overridding behavior, even for the
      _alloc() case, since keeping the original strides (probably) does not
      hurt anything. The original code has been kept commented-out, though,
      in case an unintended consequence is later discovered.
    - Fixed a typo in an error check for general stride cases where rs == cs.

    Fixed imaginary bug in quadratic partitioning code.
    
    Details:
    - Fixed a bug in the relatively new quadratic partitioning code that,
      under the right conditions, would perform sqrt() on a negative value.
      If the solution is imaginary, we discard it and use an alternate
      partition width that assumes no diagonal intersection. That alternate
      width is actually already computed, so, the fix was quite simple.
      Thanks to Devangi Parikh for reporting this bug.

    Laid groundwork for runtime memory pool resizing.
    
    Details:
    - Changed bli_pool_finalize() so that the freeing begins with the block
      at top_index instead of block 0. This allows us to use the function
      for terminal finalization as well as temporary cleanup prior to
      reinitialization. Also, clear the pool_t struct upon _pool_finalize()
      in case it is called in the terminal case with some blocks still
      checked out to threads (in which case the threads will see the new
      block size as 0 and thus release the block as intended).
    - Added bli_pool_reinit(), which calls _pool_finalize() followed by
      _pool_init() with new parameters.
    - Added bli_mem_reinit(), which is based on bli_pool_reinit().
    - Added new wrapper, _mem_compute_pool_block_sizes(), which calls
      _mem_compute_pool_block_sizes_dt().
    - Updated bli_mem_release() so that the pblk_t is freed, via
      _pool_free_block(), if the block size recorded in the mem_t at the
      time the pblk_t was acquired is now different from the value in the
      pool_t.

    Fixed obscure 3m1/4m1a bugs in trmm[3] and trsm.
    
    Details:
    - Fixed a family of bugs in the triangular level-3 operations for
      certain complex implementations (3m1 and 4m1a) that only manifest if
      one of the register blocksizes (PACKMR/PACKNR, actually) is odd:
      - Fixed incorrect imaginary stride computation in bli_packm_blk_var2()
        for the triangular case.
      - Fixed the incorrect computation of imaginary stride, as stored in
        the auxinfo_t struct in trmm and trsm macro-kernels.
      - Fixed incorrect pointer arithmetic in the trsm macro-kernels in the
        cases where the the register blocksize for the triangular matrix is
        odd. Introduced a new byte-granular pointer arithmetic macro,
        bli_ptr_add(), that computes the correct value.
    - Added cpp macro to bli_macro_defs.h for typeof() operator, defined in
      terms of __typeof__, which is used by bli_ptr_add() macro.
    - Disabled the row- vs. column-storage optimization in bli_trmm_front()
      for singleton problems because the inherent ambiguity of whether a
      scalar is row-stored or column-stored causes the wrong parameter
      combination code to be executed (by dumb luck of our checking for
      row storage first).
    - Added commented-out debugging lines to 3m1/4m1a and reference
      micro-kernels, and trsm_ll macro-kernel.

    Load balance thread ranges for arbitrary diagonals.
    
    Details:
    - Expanded/updated interface for bli_get_range_weighted() and
      bli_get_range() so that the direction of movement is specified in the
      function name (e.g. bli_get_range_l2r(), bli_get_range_weighted_t2b())
      and also so that the object being partitioned is passed instead of an
      uplo parameter. Updated invocations in level-3 blocked variants, as
      appropriate.
    - (Re)implemented bli_get_range_*() and bli_get_range_weighted_*() to
      carefully take into account the location of the diagonal when computing
      ranges so that the area of each subpartition (which, in all present
      level-3 operations, is proportional to the amount of computation
      engendered) is as equal as possible.
    - Added calls to a new class of routines to all non-gemm level-3 blocked
      variants:
        bli_<oper>_prune_unref_mparts_[mnk]()
      where <oper> is herk, trmm, or trsm and [mnk] is chosen based on which
      dimension is being partitioned. These routines call a more basic
      routine, bli_prune_unref_mparts(), to prune unreferenced/unstored
      regions from matrices and simultaneously adjust other matrices which
      share the same dimension accordingly.
    - Simplified herk_blk_var2f, trmm_blk_var1f/b as a result of more the
      new pruning routines.
    - Fixed incorrect blocking factors passed into bli_get_range_*() in
      bli_trsm_blk_var[12][fb].c
    - Added a new test driver in test/thread_ranges that can exercise the new
      bli_get_range_*() and bli_get_range_weighted_*() under a range of
      conditions.
    - Reimplemented m and n fields of obj_t as elements in a "dim"
      array field so that dimensions could be queried via index constant
      (e.g. BLIS_M, BLIS_N). Adjusted/added query and modification
      macros accordingly.
    - Defined mdim_t type to enumerate BLIS_M and BLIS_N indexing values.
    - Added bli_round() macro, which calls C math library function round(),
      and bli_round_to_mult(), which rounds a value to the nearest multiple
      of some other value.
    - Added miscellaneous pruning- and mdim_t-related macros.
    - Renamed bli_obj_row_offset(), bli_obj_col_offset() macros to

    Fixed minor alignment ambiguity bug in bli_pool.c.
    
    Details:
    - Fixed a typecasting ambiguity in bli_pool_alloc_block() in which
      pointer arithmetic was performed on a void* as if it were a byte
      pointer (such as char*). Some compilers may have already been
      interpreting this situation as intended, despite the sloppiness.
      Thanks to Aleksei Rechinskii for reporting this issue.
    - Redefined pointer alignment macros to typecast to uintptr_t instead of
      siz_t.

    Added support for Intel Haswell/Broadwell.
    
    Details:
    - Added sgemm and dgemm micro-kernels, which employ 256-bit AVX vectors
      and FMA instructions. (Complex support is currently provided by default
      induced method, 4m1a.)
    - Added a 'haswell' configuration, which uses the aforementioned kernels.
    - Inserted auto-detection support for haswell configuration in
      build/auto-detect/cpuid_x86.c.
    - Modified configure script to explicitly echo when automatic or manual
      configuration is in progress.
    - Changed beta scalar in test_gemm.c module of test suite to -1.0 to 0.9.

      the same micro-kernels as the piledriver, but with different
      cache blocksizes.

Date:   Fri Jun 19 11:31:53 2015 -0500

    Implemented dynamic allocation for packing buffers.
    
    Details:
    - Replaced the old memory allocator, which was based on statically-
      allocated arrays, with one based on a new internal pool_t type, which,
      combined with a new bli_pool_*() API, provides a new abstract data
      type that implements the same memory pool functionality but with blocks
      from the heap (ie: malloc() or equivalent). Hiding the details of the
      pool in a separate API also allows for a much simpler bli_mem.c family
      of functions.
    - Added a new internal header, bli_config_macro_defs.h, which enables
      sane defaults for the values previously found in bli_config. Those
      values can be overridden by #defining them in bli_config.h the same
      way kernel defaults can be overridden in bli_kernel.h. This file most
      resembles what was previously a typical configuration's bli_config.h.
    - Added a new configuration macro, BLIS_POOL_ADDR_ALIGN_SIZE, which
      defaults to BLIS_PAGE_SIZE, to specify the alignment of individual
      blocks in the memory pool. Also added a corresponding query routine to
      the bli_info API.
    - Deprecated (once again) the micro-panel alignment feature. Upon further
      reflection, it seems that the goal of more predictable L1 cache
      replacement behavior is outweighed by the harm caused by non-contiguous
      micro-panels when k % kc != 0. I honestly don't think anyone will even
      miss this feature.
    - Changed bli_ukr_get_funcs() and bli_ukr_get_ref_funcs() to call
      bli_cntl_init() instead of bli_init().
    - Removed query functions from bli_info.c that are no longer applicable
      given the dynamic memory allocator.
    - Removed unnecessary definitions from configurations' bli_config.h files,
      which are now pleasantly sparse.
    - Fixed incorrect flop counts in addv, subv, scal2v, scal2m testsuite
      modules. Thanks to Devangi Parikh for pointing out these
      miscalculations.
    - Comment, whitespace changes.

    Added early return to API-level _init() routines.
    
    Details:
    - Added conditional code that returns early from the API-level _init()
      routines if the API is already initialized. Actually meant for this to
      be included in 5f93cbe8.

    Introduced API-level initialization.
    
    Details:
    - Added API-level initialization state to _const, _error, _mem, _thread,
      _ind, and _cntl APIs. While this functionality will mostly go unused,
      adding miniscule overhead at init-time, there will be at least once
      instance in the near future where, in order to avoid an infinite loop,
      a certain portion of the initialization will call a query function that
      itself attempts to call bli_init(). API-level initialization will allow
      this later stage to verify that an earlier stage of initialization has
      completed, even if the overall call to bli_init() has not yet returned.
    - Added _is_initialized() functions for each API, setting the underlying
      bool_t during _init() and unsetting it during _finalize().
    - Comment, whitespace changes.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Wed Jun 10 12:53:28 2015 -0500

    Fixed bugs in _get_range(), _get_range_weighted().
    
    Details:
    - Fixed some bugs that only manifested in multithreaded instances of
      some (non-gemm) level-3 operations. The bugs were related to invalid
      allocation of "edge" cases to thread subpartitions. (Here, we define
      an "edge" case to be one where the dimension being partitioned for
      parallelism is not a whole multiple of whatever register blocksize
      is needed in that dimension.) In BLIS, we always require edge cases
      to be part of the bottom, right, or bottom-right subpartitions.
      (This is so that zero-padding only has to happen at the bottom, right,
      or bottom-right edges of micro-panels.) The previous implementations
      of bli_get_range() and _get_range_weighted() did not adhere to this
      implicit policy and thus produced bad ranges for some combinations of
      operation, parameter cases, problem sizes, and n-way parallelism.
    - As part of the above fix, the functions bli_get_range() and
      _get_range_weighted() have been renamed to use _l2r, _r2l, _t2b,
      and _b2t suffixes, similar to the partitioning functions. This is
      an easy way to make sure that the variants are calling the right
      version of each function. The function signatures have also been
      changed slightly.
    - Comment/whitespace updates.
    - Removed unnecessary '/' from macros in bli_obj_macro_defs.h.

    POSIX thread bugfixes/edits to bli_init.c, _mem.c.
    
    Details:
    - Fixed a sort-of bug in bli_init.c whereby the wrong pthread mutex
      was used to lock access to initialization/finalization actions.
      But everything worked out okay as long as bli_init() was called by
      single-threaded code.
    - Changed to static initialization for memory allocator mutex in
      bli_mem.c, and moved mutex to that file (from bli_init.c).
    - Fixed some type mismatches in bli_threading_pthreads.c that resulted
      in compiler warnings.
    - Fixed a small memory leak with allocated-but-never-freed (and unused)
      pthread_attr_t objects.
    - Whitespace changes to bli_init.c and bli_mem.c.

      except with the latter's problem sizes adjusted so that problems are
      generated with equal flop counts.

    Fixed a packing bug that manifested in trsm_r.
    
    Details:
    - Fixed a bug that caused a memory leak in the contiguous memory
      allocator. Because packm_init() was using simple aliasing when
      a subpartition object was marked as zeros by bli_acquire_mpart_*(),
      the "destination" pack object's mem_t entry was being overwritten
      by the corresponding field of the "source" object (which was likely
      NULL). This prevented the block from being released back to the
      memory allocator. But this bug only manifested when changing the
      location of packing B from outside the var1 loop to inside the
      var3 loop, and only for trsm with triangular B (side = right). The
      bug was fixed by changing the type of alias used in packm_init()
      when handling zero partition cases. Specifically, we now use
      bli_obj_alias_for_packing(), which does not clobber the destination
      (pack) object's mem_t field. Thanks to Devangi Parikh for this bug
      report.

    Implemented 3m2, 3m3 induced algorithms (gemm only).
    
    Details:
    - Defined a new "3ms" (separated 3m) pack schema and added appropriate
      support in packm_init(), packm_blk_var2().
    - Generalized packm_struc_cxk_3mi to take the imaginary stride (is_p)
      as an argument instead of computing it locally. Exception: for trmm,
      is_p must be computed locally, since it changes for triangular
      packed matrices. Also exposed is_p in interface to dt-specific
      packm_blk_var2 (and _var1, even though it does not use imaginary
      stride).
    - Renamed many functions/variables from _3mi to _3mis to indicate that
      they work for either interleaved or separated 3m pack schemas.
    - Generalized gemm and herk macro-kernels to pass in imaginary stride
      rather than compute them locally.
    - Added support for 3m2 and 3m3 algorithms to frame/ind, including 3m2-
      and 3m3-specific virtual micro-kernels.
    - Added special gemm macro-kernels to support 3m2 and 3m3.
    - Added support for 3m2 and 3m3 to testsuite.
    - Corrected the type of the panel dimension (pd_) in various macro-
      kernels from inc_t to dim_t.
    - Renamed many functions defined in bli_blocksize.c.
    - Moved most induced-related macro defs from frame/include to
      frame/ind/include.
    - Updated the _ukernel.c files so that the micro-kernel function pointers
      are obtained from the func_t objects rather than the cpp macros that
      define the function names.
    - Updated test/3m4m driver, Makefile, and run script.

    Reorganized code for induced complex methods.
    
    Details:
    - Consolidated most of the code relating to induced complex methods
      (e.g. 4mh, 4m1, 3mh, 3m1, etc.) into frame/ind. Induced methods
      are now enabled on a per-operation basis. The current "available"
      (enabled and implemented) implementation can then be queried on
      an operation basis. Micro-kernel func_t objects as well as blksz_t
      objects can also be queried in a similar maner.
    - Redefined several micro-kernel and operation-related functions in
      bli_info_*() API, in accordance with above changes.
    - Added mr and nr fields to blksz_t object, which point to the mr
      and nr blksz_t objects for each cache blocksize (and are NULL for
      register blocksizes). Renamed the sub-blocksize field "sub" to
      "mult" since it is really expressing a blocksize multiple.
    - Updated bli_*_determine_kc_[fb]() for gemm/hemm/symm, trmm, and
      trsm to correctly query mr and nr (for purposes of nudging kc).
    - Introduced an enumerated opid_t in bli_type_defs.h that uniquely
      identifies an operation. For now, only level-3 id values are defined,
      along with a generic, catch-all BLIS_NOID value.
    - Reworked testsuite so that all induced methods that are enabled
      are tested (one at a time) rather than only testing the first
      available method.
    - Reformated summary at the beginning of testsuite output so that
      blocksize and micro-kernel info is shown for each induced method
      that was requested (as well as native execution).
    - Reduced the number of columns needed to display non-matlab
      testsuite output (from approx. 90 to 80).

    Fixed bug in release of mem_t buffer.
    
    Details:
    - Fixed a bug that affects all level-2 and level-3 blocked variants. The
      bug only manifested, however, if the packing of operands (A and B in
      gemm, for example) spanned multiple nodes in the control tree. Until
      recently, the main consumers of packm were level-3 operations, all of
      which packed both input operands from blocked variant 1 (B outside of
      the loop, and A within the loop). This particular usage masked a flaw
      in the code whereby bli_obj_release_pack() would always release the
      underlying mem_t buffer (provided it was allocated), even if the buffer
      was not allocated in the current variant. This has been fixed by
      replacing all calls to bli_obj_release_pack() with calls to a new
      function, bli_packm_release(), which takes the same control tree node
      argument passed into the object's corresponding call to packm_init()
      or packv_init(). bli_packm_release() then proceeds to invoke

    Minor updates to induced complex mode management.
    
    Details:
    - Relocated bli_4mh.c, bli_4mb.c, bli_4m.c, bli_3mh.c, bli_3m.c (and
      associated headers) from frame/base to frame/base/induced.
    - Added bli_xm.? to frame/base/induced, which implements
      bli_xm_is_enabled(), which detects whether ANY induced complex method
      is currently enabled.
    - The new function bli_xm_is_enabled() is now used in bli_info.c to
      detect when an induced complex method is used, so we know when to
      return blocksizes from one of the induced methods' blocksize objects.

    Details:
    - Changed the static memory definitions to compute the maximum register
      blocksize for each datatype and add it to kc when computing the size
      of blocks of A and B. This formally accounts for the nudging of kc
      up to a multiple of mr or nr at runtime for triangular operations
      (e.g. trmm).

    Renamed 3m and 4m symbols/macros to 3mi and 4mi.
    
    Details:
    - Renamed several variables and macros from 3m/4m to 3mi/4mi. This is
      because those packing schemas were always implicitly "interleaved".
      This new naming scheme will make way for new schemas that separate
      instead of interleve the real and imaginary (and summed) parts.
    - Expanded the pack format sub-field of the pack schema field of the
      info_t to 4 bits (from 3). This will allow for more schema types
      going forward.
    - Removed old _cntl.c files for herk3m, herk4m, trmm3m, trmm4m.

    Fixed indexing bug for trmm3 via 3mh, 4mh.
    
    Details:
    - Fixed a bug that only affected trmm3 when performed via 3mh or 4mh,
      whereby micro-panels of the triangular matrix were packed with "dead
      space" between them due to failing to adjust for the fact that pointer
      arithmetic was occurring in units of complex elements while the data
      being packed consisted of real elements. It turns out that the macro-
      kernel suffered from the same bug, meaning the panels were actually
      being packed and read consistently. The only way I was able to
      discover the bug in the first place was because the packed block of A
      was overflowing into the beginning of the packed row panel of B using
      the sandybridge configuration.

    Fixed an obscure bug in 3mh/3m/4mh/4m packing.
    
    Details:
    - Modified bli_packm_blk_var1.c and _var2.c to increase the triangular
      case's panel increment by 1 if it would otherwise be odd. This is
      particularly necessary in _var2.c when handling the interleaved 3m
      or ro/io/rpi pack schemas, since division of an odd number by 2 can
      happen if both the panel length and the panel packing dimension
      (register packing blocksize) are odd, thus making their product odd.
    - Modified bli_packm_init.c so that panel strides are increased by 1
      if they would otherwise be odd, even for non-3m related packing.
    - Modified the trmm and trsm macro-kernels so that triangular packed
      micro-panels are traversed with this new "increment by 1 if odd"
      policy.
    - Added sanity checks in trmm and trsm macro-kernels that would result
      in an abort() if the conditions that would lead to a "divide odd
      integer by 2" scenario ever manifest.
    - Defined bli_is_odd(), _is_even() macros in bli_scalar_macro_defs.h.

    - Defined bli_obj_imag_stride() and bli_obj_set_imag_stride() and
      added invocations in key locations.
    - Added some basic error-checking related to imaginary stride.
    - For now, imaginary stride will not be exposed into the most-used
      BLIS APIs such as bli_obj_create(), and certainly not the
      computational APIs such as bli_dgemm().

    Defined gemm cntl function to query ukrs func_t.
    
    Details:
    - Added a new function, bli_gemm_cntl_ukrs(), that returns the func_t*
      for the gemm micro-kernels from the leaf node of the control tree.
      This allows all the func_t* fields from higher-level nodes in the tree
      to be NULL, which makes the function that builds the control trees
      slightly easier to read.
    - Call bli_gemm_cntl_ukrs() instead of the cntl_gemm_ukrs() macro in
      all bli_*_front() functions (which is needed to apply the row/column
      preference optimization).
    - In all level-3 bli_*_cntl_init() functions, changed the _obj_create()
      function arguments corresponding to the gemm_ukrs fields in higher-
      level cntl tree nodes to NULL.
    - Removed some old her2k macro-kernels.

    - Added optional flop counting to all level-3 front-ends, which is
      enabled via BLIS_ENABLE_FLOP_COUNT. The flop count can be
      reset at any time via bli_flop_count_reset() and queried via
      bli_flop_count(). Caveats:
      - flop counts are approximate for her[2]k, syr[2]k, trmm, and
        trsm operations;
      - flop counts ignore extra flops due to non-unit alpha;
      - flop counts do not account for situations where beta is zero.

      operations. This method, which the 3m/4m paper identifies as Algorithm
      "4m_1b" fissures the first loop around the micro-kernel so that the
      real sub-panel of the current micro-panel of B is multiplied against
      (both sub-panels of) all micro-panels of A, before doing the same for
      the imaginary sub-panel of the micro-panel of B. For now, only gemm is
      supported, and 4m_1b (labeled "4mb" within the framework) is not yet
      integrated into the test suite.

    Fixed obscure level-2 packing / general stride bug.
    
    Details:
    - Fixed a bug in certain structured level-2 operations that manifested
      only when the structured matrix was provided to BLIS as matrix stored
      with general stride. The bug was introduced in c472993b when the
      densify field was removed from the packm control tree node and
      associated APIs. Since then, the packed object was unconditionally
      marked with an uplo field of BLIS_DENSE. This is fine for level-3
      operations where micro-panels are always densified, but in level-2
      contexts, the underlying unblocked variant (fused or unfused) of
      structured operations (e.g. trmv) still needs to know whether to
      execute its "lower" or "upper" branches of code. Since this field
      was unconditionally being set to BLIS_DENSE, the unblocked variants
      were always executed the "else" branch, which happened to be the
      "lower" case code. Thus, running an upper case produced the wrong
      answer. This most obviously manifested in the form of failures for
      trmm, trmm3, and trsm in the test suite.
      The bug was fixed by setting the packed object's uplo field to
      BLIS_DENSE only if the schema indicated that micro-panels were to be
      packed. Otherwise, we can assume we are packing to regular row or
      column storage, as is the case with level-2 packing. Thanks to
      Francisco Igual for reporting the testsuite failures and ultimately
      leading us to this bug.

    - These changes were intended for the previous commit.
    - Defined bli_gemm_determine_kc_[fb]() and bli_gemm_determine_kc_[fb](),
      which determine blocksizes for gemm-based operations, taking special
      care to "nudge" the kc dimension up to a multiple of MR or NR for
      hemm and symm operations, as needed.
    - Changed bli_gemm_blk_var3f.c to call bli_gemm_determine_kc_f().
      instead of bli_determine_blocksize_f().
    - Comment updates to bli_trmm_blocksize.c, bli_trsm_blocksize.c.

    Relaxed constraint that KC be multiple of MR, NR.
    
    Details:
    - Relaxed a long-held requirement in register blocksizes that required
      the kernel programmer to choose a KC that was divisible by both MR
      and NR. This was very constraining on some architectures that did not
      use register blocksizes that were powers of two. The constraint is
      now enforced only for trmm and trsm, where it is needed, and it is
      now handled by "nudging" kc upward at runtime, if necessary, to be a
      multiple of MR or NR, as needed.
    - Defined bli_trmm_determine_kc_[fb]() and bli_trsm_determine_kc_[fb](),
      which determine blocksizes for trmm and trsm, taking special care to
      "nudge" the kc dimension up to a multiple of MR or NR, as needed.
    - Changed bli_trmm_blk_var3[fb].c to call bli_trmm_determine_kc_[fb]()
      instead of bli_determine_blocksize_[fb]().
    - Added safeguard to bli_align_dim_to_mult() that returns the dimension
      unmodified if the dimension multiple is zero (to avoid division by
      zero).
    - Removed cpp guard/check for KC % MR == 0 and KC % NR == 0 from
      bli_kernel_macro_defs.h.
    - Whitespace, variable name changes to bli_blocksize.c.
    - Removed old commented code from bli_gemm_cntl.c.

commit e64dba5633fc49b768b5edc7762f2b5d8a4d0588
Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Mon Oct 20 19:23:06 2014 -0500

    Re-implemented micro-panel alignment.
    
    Details:
    - This commit re-implements a feature that was removed in commit
      c2b2ab62. It was removed because, at the time, I wasn't sure how the
      micro-panel alignment feature would interact with the 4m method (when
      applied at the micro-kernrel level), and so it seemed safer to disable
      the feature entirely rather than allow possible breakage. This commit
      revisits the issue and safely re-implements the feature in a way that
      is compatible with 4m, 3m, 4mh, and 3mh (and native execution).
    - Modified the static memory pool to account for micro-panel alignment
      space.
    - Modified packm_init and blocked variants to align whole micro-panels
      by a datatype-specific alignment value that may be set by the
      configuration. (If it is not set by the configuration, it will default
      to BLIS_SIZEOF_?.)
    - Modified macro-kernels so that:
      - storage stride is handled properly given the new micro-panel
        alignment behavior;
      - indexing through 3m/4m/rih-type sub-panels, as is done by trmm and
        trsm, is more robust (e.g. will work if the applicable packing
        register blocksize is odd);
      - imaginary strides are computed and stored within auxinfo_t structs,
        which allows the virtual micro-kernels to more easily determine how
        to index into the micro-panel operands.
    - Modified virtual 3m and 4m micro-kernels to use the imaginary strides
      within the auxinfo_t structs instead of panel strides.
    - Deprecated the panel stride fields from the auxinfo_t structs.
    - Updated test suite to print out the micro-panel alignment values.

Date:   Fri Oct 17 11:19:34 2014 -0500

    Minor changes and fixes.
    
    Details:
    - Redefined bli_is_last_iter() to take thread_id and num_thread
      arguments, which allows the macro to correctly compute whether a
      given iteration is the last that the thread will compute in that
      particular loop. The new definition, however, remains disabled
      (commented out) until someone can look at this more closely, as
      the new definition seems to actually hurt performance slightly.
    - Whitespace and related updates to level-3 macro-kernels.
    - Updated test suite so that performance results in the hundreds of
      gigaflops does not disrupt the column alignment of the output.

      modules whereby the uplo bits of some packed matrix objects were not
      being set properly, resulting in false FAILURE results for those
      tests. Thanks to Tyler Smith for bringing this issue to my attention.

    - Expanded the BLIS_PACK_SCHEMA_BITS value in bli_type_defs.h to
      include all six bits presently used in the pack schema bitfield of
      the info field of obj_t structs. Prior to this commit, the macro
      constant only included the lowest five bits, which excluded the
      "is or is not packed" bit. This manifested as a strange bug in
      probably many level-2 codes that invoked packing, though we only
      observed it in ger before fixing. Thanks to Devin Matthews for
      finding and reporting this bug.

    Added high-level implementations of 4m, 3m.
    
    Details:
    - Added "4mh" and "3mh" APIs, which implement the 4m and 3m methods at
      high levels, respectively. APIs for trmm and trsm were NOT added due
      to the fact that these approaches are inherently incompatible with
      implementing 4m or 3m at high levels (because the input right-hand
      side matrix is overwritten).
    - Added 4mh, 3mh virtual micro-kernels, and updated the existing 4m and
      3m so that all are stylistically consistent.
    - Added new "rih" packing kernels (both low-level and structure-aware)
      to support both 4mh and 3mh.
    - Defined new pack_t schemas to support real-only, imaginary-only, and
      real+imaginary packing formats.
    - Added various level0 scalar macros to support the rih packm kernels.
    - Minor tweaks to trmm macro-kernels to facilitate 4mh and 3mh.
    - Added the ability to enable/disable 4mh, 3m, and 3mh, and adjusted
      level-3 front-ends to check enabledness of 3mh, 3m, 4mh, and 4m (in
      that order) and execute the first one that is enabled, or the native
      implementation if none are enabled.
    - Added implementation query functions for each level-3 operation so
      that the user can query a string that describes the implementation
      that is currently enabled.
    - Updated test suite to output implementation types for reach level-3
      operation, as well as micro-kernel types for each of the five micro-
      kernels.
    - Renamed BLIS_ENABLE_?COMPLEX_VIA_4M macros to _ENABLE_VIRTUAL_?COMPLEX.
    - Fixed an obscure bug when packing Hermitian matrices (regular packing
      type) whereby the diagonal elements of the packed micro-panels could
      get tainted if the source matrix's imaginary diagonal part contained
      garbage.

    Pass pack_t schemas into ukernels via auxinfo_t.
    
    Details:
    - Modified macro-kernels to pass the pack_t schema values for matrices
      A and B into the datatype-specific functions, where they are now
      inserted into a newly-expanded auxinfo_t struct. This gives gives the
      micro-kernels access to the pack_t schema values embedded in the
      control trees, which determine the precise format into which the
      matrix elements are packed.
    - Updated a call to bli_packm_init_pack() in src/test_libblis.c to
      remove densify argument. Meant to include this in commit c472993b.

    Removed densify argument to packm_cntl_obj_create().
    
    Details:
    - Removed the "densify" bool_t argument to bli_packm_cntl_obj_create().
      This argument was inserted very early in BLIS's development, when it
      was anticipated that the developer may sometimes wish to pack a
      Hermitian, symmetric, or triangular matrix without making it dense.
      But as it turns out, if we are packing a matrix, we always want to
      make it dense in some way or another due to the fact that the micro-
      kernel only multiplies dense micro-panels. Thus, unless/until there
      is a real need for the feature, it seems reasonable to remove it from
      the packm_cntl API.

    Retired trmm_t control tree definitions, usage.
    
    Details:
    - Replaced all trmm_t control tree instances and usage with that of
      gemm_t. This change is similar to the recent retirement of the herk_t
      control tree.
    - Tweaked packm blocked variants so that the triangular code does NOT
      assume that k is a multiple of MR (when A is triangular) or NR (when
      B is triangular). This means that bottom-right micro-panels packed for
      trmm will have different zero-padding when k is not already a multiple
      of the relevant register blocksize. While this creates a seemingly
      arbitrary and unnecessary distinction between trmm and trsm packing,
      it actually allows trmm to be handled with one control tree, instead
      of one for left and one for right side cases. Furthermore, since only
      one tree is required, it can now be handled by the gemm tree, and thus
      the trmm control tree definitions can be disposed of entirely.
    - Tweaked trmm macro-kernels so that they do NOT inflate k up to a
      multiple of MR (when A is triangular) or NR (when B is triangular).
    - Misc. tweaks and cleanups to bli_packm_struc_cxk_4m.c and _3m.c, some
      of which are to facilitate above-mentioned changes whereby k is no
      longer required to be a multiple of register blocksize when packing
      triangular micro-panels.
    - Adjusted trmm3 according to above changes.
    - Retired trmm_t control tree creation/initialization functions.

    Retired herk_t control tree definitions, usage.
    
    Details:
    - Replaced all herk_t control tree instances and usage with that of
      gemm_t, since the two types presently have the same fields. This means
      that herk, her2k, syrk, and syr2k can simply use the gemm control tree
      as-is, just as hemm and symm have been doing for some time now.
    - Retired herk_t control tree creation/initialization functions.
    - Retired many _target.c and .h files into 'old' directories.

    Minor code cleanup to bli_packm_struc_cxk*.c
    
    Details:
    - Realized that we don't need to track rs_p11 and cs_p11 for
      Hermitian/symmetric case of bli_packm_struc_cxk*(). They are always
      equal to rs_p and cs_p.

    Minor update to packm_cxk kernels.
    
    Details:
    - Changed m and n dimension parameter names to panel_dim and panel_len,
      respectively, in packm_cxk, packm_cxk_3m, packm_cxk_4m kernel wrapper
      functions. This makes the code a little easier to read since "m" and
      "n" have connotations that are not applicable here.
    - Comment updates.

    Retired portions of bli_kernel_3m/4m_macro_defs.h.
    
    Details:
    - Removed sections of bli_kernel_[4m|3m]_macro_defs.h that defined
      4m/3m-specific blocksizes after realizing that this can be done in
      bli_gemm[4m|3m]_cntl.c, since that is (mostly) the only place they
      are used.
    - The maximum cache values for 4m/3m are stll needed when computing mem
      pool dimensions in bli_mem_pool_macro_defs.h. As a workaround, "local"
      definitions in terms of the regular cache blocksizes are now in place.
    - Similarly, the register blocksizes for 4m/3m are still needed in
      bli_kernel_post_macro_defs.h. As a workaround, "local" definitions in
      terms of the regular register blocksizes are now in place.

    Changed semantics of blocksize extensions.
    
    Details:
    - Changed semantics of cache and register blocksize extensions so that
      the extended values are tracked, rather than just the marginal
      extensions.
    - BLIS_EXTEND_[MKN]C_? has been renamed BLIS_MAXIMUM_[MKN]C_?.
    - BLIS_EXTEND_[MKN]R_? has been renamed BLIS_PACKDIM_[MKN]R_?.
    - bli_blksz_ext_*() APIs have been renamed to bli_blksz_max_*(). Note
      that these "max" query routines grab the maximum value for cache
      blocksizes and the packdim value for register blocksizes.
    - bli_info_*() API has been updated accordingly.
    - All configurations have been updated accordingly.

    Pass pack schema into packm_struc_cxk*().
    
    Details:
    - Changed the interface to the packm_struc_cxk*() kernels to include
      the pack_t schema. This allows the implementation to more easily
      determine how the micro-panel is stored (row-stored column panel
      or column-stored row panel).
    - Updated packm blocked variants to pass in the schema.
    - Updated packm_ker_t function pointer definition accordingly.

    Reorganized packm implementation.
    
    Details:
    - Reorganized packm variants and structure-aware kernels so that all
      routines for a given pack format (4m, 3m, regular) reside in a single
      file.
    - Renamed _blk_var4 to _blk_var2 and generalized so that it will work
      for
      both 4m and 3m, and adjusted 4m/3m _cntl_init() functions accordingly.
    - Added a new packm_ker_t function pointer type to
      bli_kernel_type_defs.h
      to facilitate function pointer typecasting in the datatype-specific
      packm_blk_var2() functions.
    - Deprecated _blk_var3.
    - Fixed a bug in the triangular micro-panel packing facility that
      affected trmm and trmm3 with unit diagonals.

    - Renamed bli_eqri.h (and macros within) to end with 'ris' suffix.

      micro-panel packing that is too large for an existing packm ukernel.
    - Comment updates.

    Details:
    - Rather than passing the packm blocked routines a boolean value that
      represents whether the matrix is being packed to row or column storage,
      we now pass in the pack schema itself.

    Renamed packm scalar from beta to kappa.
    
    Details:
    - The packm implementation (i.e. sources files in frame/1m/packm and
      frame/1m/packm/ukernels), interchangeably used the names "beta" and
      "kappa" to refer to the optional scalar to be applied during packing.
      This commit renames all uses of "beta" to be "kappa", since "beta"
      sometimes evokes the scalar specifically on the output matrix of a
      level-2 or level-3 operation.

    Details:
    - Added extra spaces to align arguments of
      bli_obj_scalar_init_detached_copy_of(). This misalignment was due to
      the fact that the function was previously named
      bli_obj_init_scalar_copy_of() and the name change, performed in
      b444489f, was done via recursive sed commands which left subsequent
      lines untouched.

    Details:
    - Combined the 4m/3m bits into an expanded bitfield, which will encode
      the packing "format" of the micro-panels. This will allow for more
      easily and compactly encoding additional formats.
    - Other minor comment/whitespace updates to bli_type_defs.h.

      format bitfield.
    - Comment update to bli_kernel_post_macro_defs.h.

    Cleaned up front-end layering for 4m/3m.
    
    Details:
    - Added an extra layer to level-3 front-ends (examples: bli_gemm_entry()
      and bli_gemm4m_entry()) to hide the control trees from the code that
      decides whether to execute native or 4m-based implementations. The
      layering was also applied to 3m.
    - Branch to 4m code based on the return value of bli_4m_is_enabled(),
      rather than the cpp macros BLIS_ENABLE_?COMPLEX_VIA_4M. This lays
      the groundwork for users to be able to change at runtime which
      implementation is called by the main front-ends (e.g. bli_gemm()).
    - Retired some experimental gemm code that hadn't been touched in
      months.

    Added bli_4m API for querying 4m enabled state.
    
    Details:
    - Added bli_4m.c (and header), which defines a simple API that can be
      used to query, enable, and disable 4m-based complex support in BLIS.
      The macros BLIS_ENABLE_?COMPLEX_VIA_4M are now used to initialize
      the variable that determines the state (enabled or disabled).
    - Changed bli_info*() API so that all cache and register blocksize-
      related query routines return the blksz_t objects' values as they
      exist at runtime, rather than return the values as determined by the
      configuration system (e.g. bli_kernel.h, or defaults for those values
      not specified). This sets the foundation for being able to change
      those blocksizes at runtime.

    Added optional row preference to ukernel config.
    
    Details:
    - Added the ability for the kernel developer to indicate the gemm micro-
      kernel as having a preference for accessing the micro-tile of C via
      contiguous rows (as opposed to contiguous columns). This property may
      be encoded in bli_kernel.h as BLIS_?GEMM_UKERNEL_PREFERS_CONTIG_ROWS,
      which may be defined or left undefined. Leaving it undefined leads to
      the default assumption of column preference.
    - Changed conditionals in frame/3/*/*_front.c that induce transposition
      of the operation so that the transposition is induced only if there
      is disagreement between the storage of C and the preference of the
      micro-kernel. Previously, the only conditional that needed to be met
      was that C was row-stored, which is to say that we assumed the micro-
      kernel preferred column-contiguous access on C.
    - Added a "prefers_contig_rows" property to func_t objects, and updated
      calls to bli_func_obj_create() in _cntl.c files in order to support
      the above changes.
    - Removed the row-storage optimization from bli_trsm_front.c because
      it is actually ineffective. This is because the right-side case of
      trsm flips the A and B micro-panel operands (since BLIS only requires
      left-side gemmtrsm/trsm kernels), meaning any transposition done
      at the high level is then undone at the low level.
    - Tweaked trmm, trmm3 _front.c files to eliminate a possible redundant
      invocation of the bli_obj_swap() macro.

    Reorganized packm ukernels.
    
    Details:
    - Previously, packm micro-kernels were organized by the implied register
      blocksize (panel dimension) assumed by the kernel, meaning conventional,
      ri, and ri3 variations of some micro-kernel size were housed in the same
      file. This commit reorganizes the micro-kernels so that all sizes reside
      in the same file for each format type (conventional, ri, and ri3).

    Tweaks to gemm4m, gemm3m virtual ukernels.
    
    Details:
    - Fixed a potential, but as-yet unobserved bug in gemm3m that would
      allow undesirable inf/NaN propogation, since C was being scaled by
      beta even if it was equal to zero.
    - In gemm3m micro-kernel, we now avoid copying C to the temporary
      micro-tile if beta is zero.
    - Rearranged computation in gemm4m so that the temporary C micro-tile
      is accessed less, and C is accessed only after the micro-kernel
      calls. This improves performance marginally in most situations.
    - Comment updates to both gemm4m and gemm3m micro-kernels.

    Details:
    - Rolled back recent changes to bli_obj_is_row_stored() and
      bli_obj_is_col_stored() so that those macros now only inspect the
      strides (row or column). It turns out that the more sophisticated
      definitions introduced in a51e32e are not necessary, because these
      "obj" macros are virtually never used on packed matrices, and when
      they are, they can use bli_obj_is_[row|col}_packed() macros, which
      inspect the info bitfield.

    Added CBLAS compatibility layer.
    
    Details:
    - Added a new section in bli_config.h files of all configurations for
      enabling CBLAS support. (Currently, the default is for the CBLAS layer
      to be disabled.)
    - Added a directory, frame/compat/cblas, to house CBLAS source code. A
      subdirectory 'f77_sub' holds subroutine wrappers corresponding to
      subroutines found in CBLAS that allow calling some BLAS routines with
      the return value passed as the last argument rather than as an actual
      (function) return value. This was probably intended to allow CBLAS to
      avoid the whole f2c debacle altogether. However, since BLIS does not
      assume the presence of a Fortran compiler, we had to provide similar
      routines in C.
    - A script, integrate-cblas-tarball.sh, is included to streamline the
      integration of future revisions of the CBLAS source code.
    - The current tarball, cblas.tgz, that was used with the above script to
      generate the present set of CBLAS source code is also included.
    - Updated blis.h to include necessary CBLAS-related headers.

    Fix permissions error installing to non-owned directory

commit db97ce979b88c051922c2f946ce52d523c7a12c6
Author: Kevin Locke <kevin@kevinlocke.name>

    Fix permissions error installing to non-owned directory
    
    When installing to a directory which is not owned by the installing
    user, even when the user has write permission for the directory, the
    installation can fail with an error similar to the following:
    
    Installing libblis-0.1.4-7-sandybridge.a into /usr/local/lib/
    install: cannot change permissions of ‘/usr/local/lib’: Operation not permitted
    Makefile:658: recipe for target '/usr/local/lib/libblis-0.1.4-7-sandybridge.a' failed
    make: *** [/usr/local/lib/libblis-0.1.4-7-sandybridge.a] Error 1
    
    In the example case, the error occurred because the user attempted to
    install to /usr/local and /usr/local/lib is owned by root with mode 2755
    which the Makefile unsuccessfully attempted to change to 0755.
    
    Given that installing to /usr/local is likely to be quite common and the
    ownership/permissions are the default for Debian and Debian-derived
    Linux distributions (perhaps others as well), this commit attempts to
    support that use case by using mkdir rather than install to create the
    directory (which is the same approach as Automake).

    Redefined bit field macros with bitshift operator.
    
    Details:
    - Redefined many of the macros that define bit fields and bit values in
      the obj_t info field using the bitshift operator (<<). This makes it
      easier to reorder bit fields, or expand existing bit fields, or add
      new fields. The bitshifting should be evaluated by the compiler at
      compile-time.

    Reimplemented unit blocksize fix in prev commit.
    
    Details:
    - Instead of inferring the storage format of the micro-panels from within
      the packm variants, we now pass in a bool_t value that denotes whether
      the packed matrix contains row-stored column panels or column-stored
      row panels. This value can then be tested more easily inside the main
      packm variant loop.
    - Renumbered pack_t schema values in bli_type_defs.h so that there are
      now five bits, each with different meaning:
      - 4: packed or not packed?
      - 3: packed for 3m?
      - 2: packed for 4m?
      - 1: packed to panels?
      - 0: stored by rows or columns?
    - Added new macros that test for status of above bits in schema bit
      subfield, and renamed some existing macros related to 4m/3m.

    Fixed unit register blocksize brokenness.
    
    Details:
    - Fixed a breakdown in BLIS's ability to differentiate between row-stored
      and column-stored micro-panels when MR or NR is unit. When either
      register blocksize (or both) is equal to one, inspecting the strides of
      the affected packed micro-panel is no longer sufficient to determine
      whether the micro-panel is a row-stored column panel or a column-stored
      row panel (because both strides are unit). At that point, dimension
      information is necessary when invoking the bli_is_row_stored_f() and
      bli_is_col_stored_f() macros (and their "obj" counterparts). Thanks to
      Ilya Polkovnichenko for reporting this bug.
    - Added panel dimensions (m and n) to obj_t, which are set in
      packm_init() and then passed into the blocked variants to support the
      aforementioned update.

    Tweaked behavior of herk, her2k for BLAS compat.
    
    Details:
    - Updated herk_front() and her2k_front() to explicitly set the imaginary
      components of the diagonal entries of C to zero after the computation
      is complete. This is needed in case downstream applications read the
      full diagonal entries (i.e., including imaginary part), which could, in
      the absence of this modification, accumulate numerical error from
      subsequent rank-k/rank-2k updates.
    - Updated BLAS compatibility wrappers for herk and her2k to return early
      if:
        n == 0 || ( ( alpha == 0 || k == 0 ) && beta == 1 )
      This also results in the imaginary components of diagonal entries NOT
      being set to zero (see above), which is consistent with BLAS.
    - Updated mkherm to use setid instead of an inlined loop over the
      diagonal.

    Added new level-1d operation: setid.
    
    Details:
    - Defined a new level-1d operation, setid, which sets the imaginary
      elements of an object's diagonal to a single scalar. This can be
      useful, for example, when trying to make the diagonal of a Hermitian
      matrix real-valued.

    Changed order of zero dim / error checking.
    
    Details:
    - Updated level-2 and level-3 internal back-ends so that the operation's
      _check() function is called BEFORE any attempt to return early due to
      the presence of zero dimensions. This ordering makes more sense because
      (for example) object dimensions should match even if one of them is
      zero. Previously, a dimension mismatch could result in an early return
      with no error message.
    - Updated bli_check_object_buffer() so that NULL buffers result in an
      error only if the object is dimensionally non-empty (i.e., only if both
      of the object's dimensions are non-zero). This allows BLIS operations
      to be performed on dimensionally empty objects (i.e., where at least one
      dimension is zero).
    - Updated the error message associated with bli_check_object_buffer()
      to mention the newly relaxed constraint mentioned above, vis-a-vis
      non-zero dimensions.

    Inserted gemv beta-scaling bug into compat layer.
    
    Details:
    - BLAS has a peculiar bug (or feature) whereby calling gemv on a vector
      y of non-zero length and a vector x of zero length results in no action.
      Given that the operation is y := beta*y + A*x, many (most?) individuals
      would expect vector y to still be scaled by beta. BLIS, when called
      natively, handles these cases intuitively (with beta scaling).
      Unfortunately, many BLAS test suites actually check for the way this
      situation is handled. Therefore, we have decided to implement this "bug"
      in the compatibility layer so as to provide "bug-for-bug" compatibility
      with BLAS.

    Added bli_info_*() query functions.
    
    Details:
    - Added a new API family, bli_info_*(), which can be used to query
      information about how BLIS was configured. Most of these values are
      returned as gint_t, with the exception of the version string which
      is char*.
    - Changed how the testsuite driver queries information about how BLIS
      was configured (from using macro constants directly to using the
      new bli_info API).
    - Removed bli_version.c and its header file.
    - Added STRINGIFY_INT() macro to bli_macro_defs.h
    - Renamed info_t type in bli_type_defs.h to objbits_t (not because of
      an actual naming conflict, but because the name 'info_t' would now be
      somewhat misleading in the presence of the new bli_info API, as the
      two are unrelated).

    Defined _ukernel_void() wrappers to micro-kernels.
    
    Details:
    - Added wrappers for micro-kernels so that users may invoke the
      micro-kernels without knowing what the function names actually are.
      This is useful when an application wishes to call the micro-kernel
      from a shared library instance of BLIS, where the application may not
      necessarily have the luxury of grabbing the micro-kernel name(s) from
      C preprocessor macros at compile-time. Also, since the wrappers use
      void* pointers, one's environment does not need to be aware of some
      BLIS types such as scomplex and dcomplex. These wrappers now join the
      level-1 and level-1f kernel wrappers, which pre-dated this commit.
    - Removed the wrapper definitions and prototypes from the micro-kernel
      test suite modules, and replaced calls to them with calls to the new
      wrappers mentioned above.

    Fixed a bug for TRSM when BLIS_ENABLE_MULTITHREADING is not set but the multithreading environment variables are turned on

    Quick and dirty multithreading for TRSM
    
    Should work fine for small number of threads (up to 8 or maybe even 16).
    However, performance is yet untested.
    This parallelizes the "JR" loop for the left sided cases
    and the "IR" loop for the right sided cases.
    
    Future work is to parallelize the outer loops as well.

    Added shared library support to build system.
    
    Details:
    - Modified top-level Makefile to support building shared (dynamic)
      libraries.
    - Updated most configurations' make_defs.mk files to include necessary
      compiler/linker flags needed by top-level Makefile.
    - Note that by default, all configurations presently do NOT build
      shared libraries. To enable, one must change the value of
      BLIS_ENABLE_DYNAMIC_BUILD to 'yes'.

    Fixed ldim alignment bug in core2 gemm ukernel.
    
    Details:
    - Fixed a bug in the dunnington/core2 gemm micro-kernels that resulted in
      a segmentation fault if a column-stored matrix's starting address was
      aligned, but its leading dimension was such that its second column was
      unaligned. Basically, the micro-kernel was assuming that aligned load
      instructions were safe when they actually were not. An extra condition
      that checks the alignment of cs_c (ie: the leading dimension in the
      column storage case) has now been added. Thanks to Michael Lehn for
      reporting this bug.

    Changed treatment of NULL object buffers.
    
    Details:
    - Relaxed the constraint in bli_obj_attach_buffer_check(), which required
      the buffer address being attached to be non-NULL. This is acceptable
      because the user was already able to create and use objects with NULL
      buffers (via bli_obj_create_without_buffer(), which initializes the
      buffer to NULL).
    - Inserted calls to newly defined function, bli_check_object_buffer(),
      into nearly all operations' _check() or _int_check() functions. This
      allows BLIS to abort peacefully if a computational routine is called
      with an object containing a NULL buffer. By contrast, under such
      conditions, BLAS would typically fail with a segmentation fault.
    - Within operation front-ends, moved the calls to _check()/_int_check()
      so that zero dimensions are checked first (and if found, execution
      returns with trivial or no computation). This resolves issue #7. Thanks
      to Jack Poulson for reporting this bug.

    Can now query register blocksizes from blk algs.
    
    Details:
    - Added a new field to blksz_t objects that allows one to attach a
      sub-object. Doing this allows us to associate a register blocksize with
      any given cache blocksize. That way, the register blocksize can be
      queried wherever the cache blocksize would normally be accessible
      (e.g. a blocked algorithm).
    - Modified bli_gemm_cntl.c (and 4m/3m variants) so that the register
      blocksizes are attached to the cache blocksizes after they are created.

      4m/3m variants).

    Made barrier after packing implicit.
    
    This also fixed a bug where barriers in the blocked variants were inserted after the inner packing routines,
    but not the outer packing routines.
    This allowed, for instance, the block of B to not be finished being packed before computation to occur.

    Refined INSERT_GENTFUNC macro usage.
    
    Details:
    - Defined new INSERT_GENTFUNC macros so that the macro always takes
      exactly the number of arguments needed for the particular operation or
      variant being defined. Many operations were using INSERT_GENTFUNC
      macros that expected one auxiliary argument even though none were
      needed. Those instances have now been updated. Most of these instances
      were in the level-0 and -1v operations, as well as some operations
      defined in frame/util.

    Minor simplifications to trmm, trsm macro-kernels.
    
    Details:
    - Simplified some code that would have allowed the diagonal of a trmm
      or trsm triangular matrix to intersect the short end of a micro-panel.
      This is disallowed via higher-level constraints on cache blocksizes, so
      this code was never needed and only served to obfuscate.
    - Updated some comments in trmm, trsm macro-kernels.

    Reorganized norm operations.
    
    Details:
    - Completely reoganized norm operations:
      - Renames:
        - fnormsc, fnormv, fnormm -> normfsc, normfv, normfm (2-norm)
        - absumv -> norm1v (vector 1-norm)
      - New operations:
        - norm1m (matrix 1-norm)
        - normiv, normim (infinity-norm)
        - amaxv (BLAS-like absolute maximum value index)
        - asumv (BLAS-like absolute sum)
    - Deprecated absumm, as it did not correspond to any actual norm.
      (However, an inlined version now exists in the testsuite module for
      randm.)

    Minor fixes to sumsqv, abmaxv.
    
    Details:
    - Minor update to bli_sumsqv_unb_var1() to bring it up-to-date with
      LAPACK 3.5.0's zlassq.f, which, starting with 3.4.2, returns NaN when
      the vector (or matrix) contains a NaN.
    - Minor change to bli_abmaxv_unb_var1() to more closely mimic the
      behavior of netlib BLAS's izamax(). There, a "less than or equal to"
      operator is used in the search instead of "less than", which would
      change the element index returned if there were multiple maximum values.
    - Added macro function definitions for bli_isinf() and bli_isnan(), which
      are currently implemented in terms of isinf() and isnan() from math.h.

    Fixed various bugs when C99 complex is enabled.
    
    Details:
    - Fixed various bugs in packm_*_cxk(), the 4m/3m micro-kernels, and
      elsewhere in the framework that were not yet set up to work properly
      when BLIS_ENABLE_C99_COMPLEX is defined in bli_config.h
    - Extensive changes to f2c-derived files in frame/compat/f2c to allow
      C99 complex storage. Most of these changes center around accessing
      real and imaginary components via bli_?real()/bli_?imag() accessor
      macros, and setting of values via bli_?sets() assignment macros.
      (Thanks to Vladimir Sukarev for pointing out that _ENABLE_C99_COMPLEX
      was broken.)

    In packm variant 1, the variable p_begin was incremented each iteration, causing a dependency.
    This dependeny was removed, allowing each iteration to be executed in parallel.
    
    Somewhere in bli_threading.c, I was allocating an array of pointers instead of an array of structs.

      configurations. It was already going unused in packm_init() since the
      recent 4m/3m commit. This setting was rarely, if ever, useful, and its
      existence only posed a potential risk for 4m/3m-based implementations.
    - Removed BLIS_CONTIG_STRIDE_ALIGN_SIZE usage from mem_pool_macro_defs.h.
    - Updated comments regarding CONTIG_STRIDE_ALIGN_SIZE in template
      micro-kernels.

commit fde5f1fdece19881f50b142e8611b772a647e6d2 (tag: 0.1.1)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Tue Feb 25 13:34:56 2014 -0600

    Added extensive support for configuration defaults.
    
    Details:
    - Standard names for reference kernels (levels-1v, -1f and 3) are now
      macro constants. Examples:
        BLIS_SAXPYV_KERNEL_REF
        BLIS_DDOTXF_KERNEL_REF
        BLIS_ZGEMM_UKERNEL_REF
    - Developers no longer have to name all datatype instances of a kernel
      with a common base name; [sdcz] datatype flavors of each kernel or
      micro-kernel (level-1v, -1f, or 3) may now be named independently.
      This means you can now, if you wish, encode the datatype-specific
      register blocksizes in the name of the micro-kernel functions.
    - Any datatype instances of any kernel (1v, 1f, or 3) that is left
      undefined in bli_kernel.h will default to the corresponding reference
      implementation. For example, if BLIS_DGEMM_UKERNEL is left undefined,
      it will be defined to be BLIS_DGEMM_UKERNEL_REF.
    - Developers no longer need to name level-1v/-1f kernels with multiple
      datatype chars to match the number of types the kernel WOULD take in
      a mixed type environment, as in bli_dddaxpyv_opt(). Now, one char is
      sufficient, as in bli_daxpyv_opt().
    - There is no longer a need to define an obj_t wrapper to go along with
      your level-1v/-1f kernels. The framework now prvides a _kernel()
      function which serves as the obj_t wrapper for whatever kernels are
      specified (or defaulted to) via bli_kernel.h
    - Developers no longer need to prototype their kernels, and thus no
      longer need to include any prototyping headers from within
      bli_kernel.h. The framework now generates kernel prototypes, with the
      proper type signature, based on the kernel names defined (or defaulted
      to) via bli_kernel.h.
    - If the complex datatype x (of [cz]) implementation of the gemm micro-
      kernel is left undefined by bli_kernel.h, but its same-precision real
      domain equivalent IS defined, BLIS will use a 4m-based implementation
      for the datatype x implementations of all level-3 operations, using
      only the real gemm micro-kernel.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Wed Feb 19 17:00:52 2014 -0600

    Added level-3 support for complex via 4m-/3m.
    
    Details:
    - Added the ability to induce complex domain level-3 operations via new
      virtual complex micro-kernels which are implemented via only real
      domain micro-kernels. Two new implementations are provided: 4m and 3m.
      4m implements complex matrix multiplication in terms of four real
      matrix multiplications, where as 3m uses only three and thus is
      capable of even higher (than peak) performance. However, the 3m method
      has somewhat weaker numerical properties, making it less desirable
      in general.
    - Further refined packing routines, which were recently revamped, and
      added packing functionality for 4m and 3m.
    - Some modifications to trmm and trsm macro-kernels to facilitate indexing
      into micro-panels which were packed for 4m/3m virtual kernels.
    - Added 4m and 3m interfaces for each level-3 operation.
    - Various other minor changes to facilitate 4m/3m methods.

    Minor fixes to trsm consistent with prev on trmm.
    
    Details:
    - Removed use of bli_min() and bli_max() that were only being used to
      try to support situations where the diagonal would intersect the
      short end of some micro-panels, which is situation that is disallowed
      at a higher level by various constraints on the register and cache
      blocksize. This only affected trsm_ll and trsm_lu.
    - Use panel stride as passed into the macro-kernel rather than compute
      it via k and PACKMR/PACKNR. This affects all macro-kernels of trsm.

    Fixed obscure bug in trmm_ll, trmm_lu.
    
    Details:
    - Fixed an obscure bug in left-hand trmm that would only manifest when
      non-zero register blocksize extensions (PACKMR > MR or PACKNR > NR)
      are used.
    - Removed use of bli_min() and bli_max() that were only being used to
      try to support situations where the diagonal would intersect the
      short end of some micro-panels, which is situation that is disallowed
      at a higher level by various constraints on the register and cache
      blocksize. This only affected trmm_ll and trmm_lu.
    - Use panel stride as passed into the macro-kernel rather than compute
      it via k and PACKMR/PACKNR. This affects all macro-kernels of trmm.

    Fixed an obscure bug in packm_cxk().
    
    Details:
    - Fixed a bug in packm_cxk() whereby the packm ukernel was being chosen
      from ldp, which is always equal to PACKMR or PACKNR. The problem with
      this is that the pack ukernels were implicitly assuming that the
      panel dimension of the panel being packed was equal to ldp, which
      is not the case when the register blocksizes extensions are non-zero
      (ie: when PACKMR > MR or PACKNR > NR, whichever is applicable). This
      problem has been fixed by passing ldp into the pack ukernels, which
      now walk through the packed micro-panel region by incrementing by this
      value, rather than incrementing by the inherent panel dimension value
      assumed by each packm ukernel (e.g. 4 in the case of packm_ref_4xk).
    - Also fixed a very minor edge case inefficiency whereby pack ukernels
      smaller than the default were not being used in edge cases, and instead
      those situations were being handled by scal2m. This is related to the
      issue above, because the pack ukernel itself was being chosen based on
      ldp instead of the panel dimension.

    Details:
    - Consolidated the functionality previously supported by packm_blk_var2()
      and packm_blk_var3() into a new variant, packm_blk_var1().
    - Updates to packm_gen_cxk(), packm_herm_cxk.c(), and packm_tri_cxk()
      to accommodate above changes.
    - Removed packm_blk_var3() and retired packm_blk_var2() to
      frame/1m/packm/old.
    - Updated all level-3 _cntl_init() functions so that the new, more
      versatile packm_blk_var1 is used for all level-3 matrix packing.

    Details:
    - Revised packm_blk_var2() and _var3() by encapsulating the general,
      hermitian/symmetric, and triangular panel-packing subproblems into
      separate functions: packm_gen_cxk(), packm_herm_cxk(), and
      packm_tri_cxk(), respectively. Also, homogenized the packm code as
      well as the new specialized packm_*_cxk() code to further improve
      readability.

    Employ simpler INSERT_ macro for ref ukernels.
    
    Details:
    - Defined a new macro, INSERT_GENTFUNC_BASIC0, which takes only one
      argument--the base name of the function--and employed this macro
      in the reference micro-kernel files instead of the _BASIC macro,
      which takes one auxiliary argument. That argument was not being
      used and probably just acted to unnecessarily obfuscate.

    Updated comments in macro-kernels.
    
    Details:
    - Updated (and fixed some errors in) the "Assumptions/assertions" comment
      section of macro-kernels.
    - Changed register blocksizes of reference configuration to MR = 8 and
      NR = 4. It's always good for MR != NR in the reference configuration
      since it may help uncover bugs related to non-square micro-kernels.

    Pass panel dimensions into macro-kernels.
    
    Details:
    - Modified the interfaces to the datatype-specific macro-kernels so that:
      - pd_a and pd_b are passed in (which contain the panel dimensions of
        packed panels of a and b).
      - rs_a and cs_b are no longer passed in (they were guaranteed to be 1).
    - Modified implementations of datatype-specific macro-kernels so pd_a,
      pd_b, cs_a, and rs_b are used instead of cpp macros for MR, NR, PACKMR,
      and PACKNR, respectively.
    - Declare temporary c matrices (ct) as being maxmr-by-maxnr, which for now
      is equivalent to being mr-by-nr. maxmr and maxnr are declared in a new
      header file bli_kernel_post_macro_defs.h.

    Details:
    - Added some logic to packm_init(), pack_int() and gemm_int() so that
      (a) objects marked as BLIS_ZEROS are not packed, and (b) those
      objects are not computed with. This functionality is not currently
      needed by any existing implementations, but may be used in the
      future.

    Removed redundant non-gemm blksz_t creation.
    
    Details:
    - Removed code that creates duplicate blksz_t objects for herk, trmm,
      and trsm. Instead, the gemm blksz_t objects are accessed via extern
      and used directly. This reduces the amount of code associated with
      each of the three _cntl_init() and _cntl_finalize() function.

    Introduced new level-3 front-end layer.
    
    Details:
    - Added new _front() functions for each level-3 operation. This is done
      so that the choosing of the control tree (and *only* the choosing of
      the control tree) happens in what was previously the "front end"
      (e.g. bli_gemm()). That control tree is then passed into the _front()
      function, which then performs up-front tasks such as parameter
      checking.

    Details:
    - Removed code that generated a control tree specifically for hemm and
      symm. Instead, the gemm control tree is now configured so that it
      works for gemm, hemm, or symm.
    - Retired most her2k code, as it was not being used. (Currently, her2k is
      implemented as two invocations of herk.) I couldn't think of many
      situations where her2k variants were needed.
    - Removed some older her2k code.

    Embed func_t microkernel objects in control trees.
    
    Details:
    - Modified all control tree node definitions to include a new field of
      type func_t*, which is similar to a blksz_t except that it contains
      one function pointer (each typed simply as void*) for each datatype.
      We use the func_t* to embed pointers to the micro-kernels to use for
      the leaf-level nodes of each control tree. This change is a natural
      extension of control trees and will allow more flexibility in the
      future.
    - Modified all macro-kernel wrappers to obtain the micro-kernel pointers
      from the incomming (previously ignored) control tree node and then pass
      the queried pointer into the datatype-specific macro-kernel code, which
      then casts the pointer to the appropriate type (new typedefs residing
      in bli_kernel_type_defs.h) and then uses the pointer to call the micro-
      kernel. Thus, the micro-kernel function is no longer "hard-coded" (that
      is, determined when the datatype-specific macro-kernel functions are
      instantiated by the C preprocessor).
    - Added macros to bli_kernel_macro_defs.h that build datatype-specific
      base names if they do not exist already, and then uses those to build
      datatype-specific micro-kernel function names. This will allow
      developers extra flexibility if they wanted to, for example, name each
      of their datatype-specific micro-kernels differently (e.g. double
      real might be named bli_dgemm_opt_4x4() while double complex might be
      named bli_zgemm_opt_2x2()).
    - Inserted appropriate code into _cntl_init() functions that allocates
      and initializes a func_t object for the corresponding micro-kernels.
      The gemm ukernel func_t object is created once, in bli_gemm_cntl_init(),
      and then reused via extern wherever possible.

    Details:
    - Removed commented-out code from macro-kernels that was supposed to
      facilitate implementing mixed domain (complex times real) matrix
      multiplication. This functionality is still (probably possible),
      but I'm getting tired of looking at the code every time I edit
      a macro-kernel. Plus, there are probably ways of doing it at a
      higher level, via control trees.

    Removed b_aux field from cntl nodes.
    
    Details:
    - Removed b_aux field from all control tree node definitions. This field
      was being used in certain optimizations (incremental blocking) that were
      not actually being employed within BLIS, and are probably not employed
      by others.
    - Updated all _cntl_obj_create() function definitions and invocations
      according to above change.
    - Retired bli_gemm_blk_var4.c, which was one such function that employed
      incremental blocking, but which was never called by BLIS itself.

    Consolidated pack_t enums; retired VECTOR value.
    
    Details:
    - Changed the pack_t enumerations so that BLIS_PACKED_VECTOR no longer has
      its own value, and instead simply aliases to BLIS_PACKED_UNSPEC. This
      makes room in the three pack_t bits of the info field of obj_t so that
      two values are now unused, and may be used for other future purposes.
    - Updated sloppy terminology usage in comments in level-2 front-ends.
      (Replaced "is contiguous" with more accurate "has unit stride".)

    - Redirect errors to /dev/null when using 'find' to locate libraries that
      would be uninstalled upon executing "make uninstall-old". Before, if the
      Makefile was read before $(INSTALL_PREFIX)/lib existed, a "No such file
      or directory" message was emitted. This message was harmless, but is now
      suppressed in this situation.

    - In the test suite driver, inserted an explicit typecast of the return
      value of bli_getopt() prior parsing. The lack of typecast caused a

      interpreted as garbage character. Thanks to Francisco Igual for finding

    Allow building outside source distribution.
    
    Details:
    - Modified build system (mostly configure and top-level Makefile) so that
      a user can build a BLIS library outside of the top-level directory of
      the source distribution.
    - Added "test" target to Makefile so that the user can run "make test",
      which will compile, link, and run the testsuite binary. This works even
      if the build directory is externally located, thanks to the test suite
      binary's new -g and -o command-line options. Also, when creating the
      test suite via the top-level Makefile, the linking is against the
      local archive, in lib/<configname>, rather than at <install_prefix>/lib.
    - Modified testsuite/Makefile so that it links against the library built
      locally, in ../lib/<configname>.
    - Added "-lm" to LDFLAGS of most configurations' make_defs.mk.
    - Various other cleanups to build system.

    Implemented bli_getopt().
    
    Details:
    - Added bli_getopt.c and .h files to frame/base. These files implement
      a custom version of getopt(), which may be used to parse command line
      options passed into a program via argc/argv. I am implementing this
      function myself, as opposed to using the version available via unistd.h,
      for portability reasons, as the only requirements are string.h (which
      is available via the standard C library).
    - Modified test suite to allow the user to specify the file name (and/or
      path) to the parameters and operations input files: -g may be used to
      specify the general input file and -o to specify the operations input
      file). If -g or -o or both are not given, default filenames are assumed
      (as well as their existence in the current directory).

    Removed error checks in netlib->BLIS param mapping
    
    Details:
    - Disabled error checking in netlib-to-BLIS parameter mapping functions.
      If the char value input to these functions was not one of the defined
      values, bli_check_error_code() with the appropriate error code value
      would be called, resulting in an abort(). This was unnecessary and
      redundant since these routines are currently only used within the
      BLAS compatibility layer, and they are only called AFTER parameter
      checking has already been performed on the original BLAS char values.
      If the application tried to override xerbla() to prevent an abort()
      from being called, this error checking would still get in the way.
      Thus, instead of reporting the error situation to the framework (ie:
      calling abort()), an arbitrary BLIS parameter value is now chosen and
      the function returns normally. Thanks to Jeff Hammond for finding and
      reporting this issue.

    Store variable panel strides in trmm/trsm auxinfo.
    
    Details:
    - Changed the value being stored into the auxinfo_t structure in trmm
      and trsm macro-kernels. Whereas before we stored whatever value was
      provided to the macro-kernel implementation via ps_a/ps_b, now we
      store the stride that will advance to the next variable-length
      micro-panel of the triangular matrix A (left) or B (right).
    - Whitespace changes to the files affected above.

    - Removed a_next and b_next arguments to micro-kernels and replaced them
      with a pointer to a new datatype, auxinfo_t, which is simply a struct
      that holds a_next and b_next. The struct may hold other auxiliary
      information that may be useful to a micro-kernel, such as micro-panel
      stride. Micro-kernels may access struct fields via accessor macros
      defined in bli_auxinfo_macro_defs.h.
    - Updated all instances of micro-kernel definitions, micro-kernel calls,
      as well as macro-kernels (for declaring and initializing the structs)
      according to above change.

    Added "ri" scalar macros.
    
    Details:
    - Added set of basic scalar macros that take arguments' real and
      imaginary components separately, named like the previous set except
      with the "ris" (instead of "s") suffix.
    - Redefined the previous set of scalar macros (those that take arguments
      "whole") in terms of the new "ri" set.
    - Renamed setris and getris macros to sets and gets.
    - Renamed setimag0 macros to seti0s.
    - Use bli_?1 macro instead of a local constant in bla_trmv.c, bla_trsv.c.

    Details:
    - Fixed copy-and-paste bug whereby [scz]gemmtrsm_u_opt_d4x4 kernels
      for x86_64/core2 were calling the wrong reference code (l instead
      of u).
    - Fixed some unused variables in x86_64/core2 dotaxpyv and dotxaxpyf

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Tue Dec 3 16:08:30 2013 -0600

    Added new "attached" scalar representation.
    
    Details:
    - Added infrastructure to support a new scalar representation, whereby
      every object contains an internal scalar that defaults to 1.0. This
      facilitates passing scalars around without having to house them in
      separate objects. These "attached" scalars are stored in the internal
      atom_t field of the obj_t struct, and are always stored to be the same
      datatype as the object to which they are attached. Level-3 variants no
      longer take scalar arguments, however, level-3 internal back-ends stll
      do; this is so that the calling function can perform subproblems such
      as C := C - alpha * A * B on-the-fly without needing to change either
      of the scalars attached to A or B.
    - Removed scalar argument from packm_int().
    - Observe and apply attached scalars in scalm_int(), and removed scalar
      from interface of scalm_unb_var1().
    - Renamed the following functions (and corresponding invocations):
    
       bli_obj_init_scalar_copy_of()
                               -> bli_obj_scalar_init_detached_copy_of()
       bli_obj_init_scalar()   -> bli_obj_scalar_init_detached()
       bli_obj_create_scalar_with_attached_buffer()
                               -> bli_obj_create_1x1_with_attached_buffer()
       bli_obj_scalar_equals() -> bli_obj_equals()
    
    - Defined new functions:
    
       bli_obj_scalar_detach()
       bli_obj_scalar_attach()
       bli_obj_scalar_apply_scalar()
       bli_obj_scalar_reset()
       bli_obj_scalar_has_nonzero_imag()
       bli_obj_scalar_equals()
    
    - Placed all bli_obj_scalar_* functions in a new file, bli_obj_scalar.c.
    - Renamed the following macros:
    
       bli_obj_scalar_buffer() -> bli_obj_buffer_for_1x1()
       bli_obj_is_scalar()     -> bli_obj_is_1x1()
    
    - Defined new macros to set and copy internal scalars between objects:
    
       bli_obj_set_internal_scalar()
       bli_obj_copy_internal_scalar()
    
    - In level-3 internal back-ends, added conditional blocks where alpha and
      beta are checked for non-unit-ness. Those values for alpha and beta are
      applied to the scalars attached to aliases of A/B/C, as appropriate,
      before being passed into the variant specified by the control tree.
    - In level-3 blocked variants, pass BLIS_ONE into subproblems instead of
      alpha and/or beta.
    - In level-3 macro-kernels, changed how scalars are obtained. Now, scalars
      attached to A and B are multiplied together to obtain alpha, while beta
      is obtained directly from C.
    - In level-3 front-ends, removed old function calls meant to provide
      future support for mixed domain/precision. These can be added back later
      once that functionality is given proper treatment. Also, removed the
      creating of copy-casts of alpha and beta since typecasting of scalars
      is now implicitly handled in the internal back-ends when alpha and
      beta are applied to the attached scalars.

    Details:
    - Updated arm, bgq, loongson3a, and x86_64 kernels so that unimplemented
      datatypes call the corresponding reference kernel. Previously, these
      kernel functions called abort() with a "not yet implemented" error
      message.

    Removed optional scaling from packm control tree.
    
    Details:
    - Removed does_scale field from packm control tree node and
      bli_packm_cntl_obj_create() interface. Adjusted all invocations of
      _cntl_obj_create() accordingly.
    - Redefined/renamted macros that are used in aliasing so that now,
      bli_obj_alias_to() does a full alias (shallow copy) while
      bli_obj_alias_for_packing() does a partial alias that preserves the
      pack_mem-related fields of the aliasing (destination) object.
    - Removed bli_trmm3_cntl.c, .h after realizing that the trmm control tree
      will work just fine for bli_trmm3().
    - Removed some commented vestiges of the typecasting functionality needed
      to support heterogeneous datatypes.

    Outer-to-inner 'restrict' fix in macro-kernels.
    
    Details:
    - Fixed sloppy placement of 'restrict' pointer declarations in level-3
      macro-kernels. Previously, all restricted pointers were being declared
      at the outer-most function scope level. While this violates the C99
      standard, very few of the compilers used with BLIS so far have seemed
      to care. The lone exception has been IBM's xlc. Thanks to Tyler Smith
      for identifying this bug (and suggesting the fix).

    - Commented out object-wrappers in level-1f front-ends. These were not
      working as intended the reference configuration was selected, because
      most kernel sets, such as those in the template set, do not have object
      wrappers.

    Changed dim_t and inc_t to be signed integers.
    
    Details:
    - Redefined dim_t and inc_t in terms of gint_t (instead of guint_t).
      This will facilitate interoperability with Fortran in the future.
      (Fortran does not support unsigned integers.)
    - Redefined many instances of stride-related macros so that they return
      or use the absolute value of the strides, rather than the raw strides
      which may now be signed. Added new macros bli_is_row_stored_f() and
      bli_is_col_stored_f(), which assume positive (forward-oriented) strides,
      and changed the packm_blk_var[23] variants to use these macros instead
      of the existing bli_is_row_stored(), bli_is_col_stored().
    - Added/adjusted typecasting to to various functions/macros, including
      bli_obj_alloc_buffer(), bli_obj_buffer_at_off(), and various pointer-
      related macros in bli_param_macro_defs.h.
    - Redefined bli_convert_blas_incv() macro so that the BLAS compatibility
      layer properly handles situations where vector increments are negative.
      Thanks to Vladimir Sukharev for pointing out this issue.
    - Changed type of increment parameters in bli_adjust_strides() from dim_t
      to inc_t. Likewise in bli_check_matrix_strides().
    - Defined bli_check_matrix_object(), which checks for negative strides.
    - Redefined bli_check_scalar_object() and bli_check_vector_object() so
      that they also check for negative stride.
    - Added instances of bli_check_matrix_object() to various operations'
      _check routines.

      is now enforced when the matrix is packed (bli_packm_blk_var2). Thanks
      to Vladimir Sukharev for reporting this bug.

    Fixed bugs in scalm and setm.
    
    Details:
    - Fixed bugs in scalm and setm that resulted in segmentation faults when
      beta is not the same type as the matrix operand. Thanks to Vladimir
      Sukharev for reporting this bug.
    - Changed axpym and scal2m front-ends in fashion similar to that of scalm
      and setm; namely, the alpha scalar is copy-cast the type of the first
      matrix operand.
    - Changed the template and reference configurations' bli_config.h files
      so that the number of memory allocator blocks of A and B are set based
      on BLIS_MAX_NUM_THREADS.
    - Comment updates to bli_obj.c and variable rename in bla_nrm2.c.

    Fixed over/under-flow in complex inversion.
    
    Details:
    - Fixed the complex bli_?inverts() macros, which were inverting elements
      in an "unsafe" manner, such that very large and very small values were
      unnecessarily over/under-flowing. Thanks for Vladimir Sukharev for
      reporting this bug.
    - Comment update to bli_sumsqv_unb_var1.c.
    - Removed redundant bli_min() macro in bli_scalar_macro_defs.h.
    - Changed 1.0F to 1.0 for bli_drands() macro.

    Fixed parameter checking issue in BLAS syr[2]k.
    
    Details:
    - Fixed a minor parameter checking bug in the BLAS compatibility layer
      for [sd]syrk and [sd]syr2k. Specifically, if 'C' is passed in for the
      trans parameter of either operation, it is (a) allowed, and (b) treated
      as 'T' (whereas previously it was disallowed). Thanks for Vladimir
      Sukharev for finding and reporting this bug.

    Details:
    - Added a kernel directory for kernels developed by Francisco Igual for
      the Sandy Bridge architecture, including a dgemm ukernel coded with
      AVX intrinsics.
    - Added a configuration for Sandy Bridge using values supplied by Fran.

    Details:
    - Fixed a minor performance bug in bli_gemm_ker_var2.c (and the experimental
      bli_gemm_ker_var5.c) whereby the addresses for a_next and b_next are not
      computed correctly (ie: do not wraparound) at the edge cases. Thanks to
      Tze Meng for helping me identify this bug.

    Added fusing factors, MR/NR to test suite output.
    
    Details:
    - Updated the test suite driver (and modules where appropriate) so that
      the level-1f fusing factors are output along with the variable dimension.
      While this is not strictly necessary, since the fusing factors are output
      in the initial parameter summary, it allows extra reassurance to the user
      since the fusing factors appear alongside the variable dimension, which
      together give a complete picture of the problem size. Similar changes were
      made for outputting the register blocksizes when reporting results for the
      micro-kernel test modules.

    Added test suite modules for level-1f, 3 kernels.
    
    Details:
    - Added test modules in test suite for level-1f kernels and level-3
      micro-kernels. (Duplication in the micro-kernels, for now, is NOT
      supported by these test modules.)
    - Added section override switches to test suite's input.operations file.
    - Added obj_t APIs for level-1f front-ends and their unblocked variants to
      facilitate the level-1f test modules. Also added front-end for dupl
      operation.
    - Added obj_t-based check routines for level-1f operations, which are
      called from the new front-ends mentioned above.
    - Added query routines for axpyf, dotxf, and dotxaxpyf that return fusing
      factors as a function of datatype, which is needed by their respective
      test modules.
    - Whitespace changes to bli_kernel.h of all existing configurations.

    Added section overrides to test suite.
    
    Details:
    - Added new lines of input to the test suite's input.operations file, which
      allows the user to disable entire sections (levels) of tests. Before this
      change, the user had to manually disable each operation tests's "master
      switch". (This is why input.operations.0 existed: to allow a more
      convenient starting point for someone who only wanted to test one or a
      few operations.)

    Added template implementations and other tweaks.
    
    Details:
    - Added a 'template' configuration, which contains stub implementations of the
      level 1, 1f, and 3 kernels with one datatype implemented in C for each, with
      lots of in-file comments and documentation.
    - Modified some variable/parameter names for some 1/1f operations. (e.g.
      renaming vector length parameter from m to n.)
    - Moved level-1f fusing factors from axpyf, dotxf, and dotxaxpyf header files
      to bli_kernel.h.
    - Modifed test suite to print out fusing factors for axpyf, dotxf, and
      dotxaxpyf, as well as the default fusing factor (which are all equal
      in the reference and template implementations).
    - Cleaned up some sloppiness in the level-1f unb_var1.c files whereby these
      reference variants were implemented in terms of front-end routines rather
      that directly in terms of the kernels. (For example, axpy2v was implemented
      as two calls to axpyv rather than two calls to AXPYV_KERNEL.)
    - Changed the interface to dotxf so that it matches that of axpyf, in that
      A is assumed to be m x b_n in both cases, and for dotxf A is actually used
      as A^T.
    - Minor variable naming and comment changes to reference micro-kernels in
      frame/3/gemm/ukernels and frame/3/trsm/ukernels.

        Intel MIC
        IBM BG/Q
        IBM Power7
        AMD Piledriver
        Loogson 3A
      and reorganized kernels directory. Thanks to Tyler Smith, Mike Kistler,
      and Xianyi Zhang for contributing these kernels.
    - Added configurations corresponding to above architectures, and renamed
      "clarksville" configuration to "dunnington".

    Removed default configuration behavior.
    
    Details:
    - Changed the configure script so that it no longer defaults to the
      reference configuration. This change is being made so that the
      developer has a firm awareness of which configuration is being used
      to configure BLIS. Thanks to Mike Kistler and Bryan Marker for this
      suggested change.

    Minor improvements to static memory allocator.
    
    Details:
    - Expanded on cpp macro definitions from bli_mem.c and relocated them to
      a new header file, frame/include/bli_mem_pool_macro_defs.h. The expanded
      functionality includes computing the pool size for each datatype (using
      that datatype's cache blocksizes) and using the maximum to size the
      actual pool array. This addresses the somewhat common pitfall whereby a
      developer updates cache blocksizes in bli_kernel.h for only one datatype
      (say, single-precision real), while the memory pools are sized using the
      double-precision real values. Then, when the developer attempts to link
      to and run a level-3 BLIS routine (e.g. dgemm), the library aborts with
      a message saying the static memory pool was exhausted. Clearly, this
      message is misleading when the pool was not sized properly to begin with.
    - Removed previously disabled code in bli_kernel_macro_defs.h that was
      meant to check for size consistency among the various cache blocksizes.
      (Obviously the memory pool size-based solution mentioned above is better.)
    - Added BLIS_SIZEOF_? cpp macros to bli_type_defs.h. This seemed like a
      reasonable place to put these constants, rather than further crowd up
      bli_config.h.
    - Updated testsuite driver to output memory pool sizes for A, B, and C.
    - Minor comment updates to bli_config.h.
    - Removed 'flame' configuration. It was beginning to get out-of-date, and
      I hadn't used it in months. We can always re-create it later.

    Various changes to treatment of integers.
    
    Details:
    - Added a new cpp macro in bli_config.h, BLIS_INT_TYPE_SIZE, which can be
      assigned values of 32, 64, or some other value. The former two result in
      defining gint_t/guint_t in terms of 32- or 64-bit integers, while the latter
      causes integers to be defined in terms of a default type (e.g. long int).
    - Updated bli_config.h in reference and clarksville configurations according
      to above changes.
    - Updated test drivers in test and testsuite to avoid type warnings associated
      with format specifiers not matching the types of their arguments to printf()
      and scanf().
    - Inserted missing #include "bli_system.h" into blis.h (which was slated for
      inclusion in d141f9eeb6d1).
    - Added explicit typecasting of dim_t and inc_t to macros in
      bli_blas_macro_defs.h (which are used in BLAS compatibility layer).
    - Slight changes to CREDITS and INSTALL files.
    - Slight tweaks to Windows build system, mostly in the form of switching to
      Windows-style CRLF newlines for certain files.

    Details:
    - Used void-casts of certain variables to appease gcc (and perhaps other
      compilers) when such variables are only used in the complex instances of
      the functions. Special thanks to Karl Rupp for suggesting a portable fix
      for these warnings.

    - Added a 'windows' directory, which contains a Windows build system
      similar to that of libflame's. Thanks to Martin for getting this up
      and running.
    - Spun off system header #includes into bli_system.h, which is included
      in blis.h
    - Added a Windows section to bli_clock.c (similar to libflame's).

      and unsigned long int, respectively.
    - Changed testsuite default max problem size to 500.
    - Changed testsuite input.operations to use square problems for level-3
      operation tests.

    Falling back to 32-bit integers for dim_t, etc.
    
    Details:
    - In light of recent segfaulting issues when compiling on 32-bit systems,
      I've changed the default typedef for gint_t and guint_t from int64_t and
      uint64_t to int32_t and uint32_t, respectively.
    - Disabled 64-bit integers in the blas2blis layer for the reference
      configuration.
    - Added type sizes of gint_t, guint_t, and the four floating-point datatypes
      to introductory output of the testsuite.

      matlab/octave format so that one can output in matlab format
      independently from outputting to files.
    - Adjusted input.operations according to above.
    - Added input.operations.0 and input.operations.1 with all options
      disabled and enabled, respectively.

    - Fixed a bug in bli_acquire_mpart_t2b() and bli_acquire_mpart_l2r()
      that cause incorrect partitioning when SUBPART0 was requested. This
      bug was introduced in 46d3d09d49ad. Thanks to Bryan for isolating
      this bug.
    - Removed dupl kernels from kernels/x86_64/3 directory.

    Moved init_safe(), finalize_safe() to BLAS compat.
    
    Details:
    - Moved the bli_init_safe() and bli_finalize_safe() function calls from the
      BLAS-like BLIS layer to the BLAS compatibility layer. Having these auto-
      initializers in the BLIS layer wasn't buying us anything because the user
      could still call the library with uninitialized global scalar constants,
      for example. Thus, we will just have to live with the constraint that
      bli_init() MUST be called before calling ANY routine with a bli_ prefix.
    - Added the missing _init_safe() and finalize_safe() calls to the level-1
      BLAS compatibility wrappers.

    Miscellaneous updates.
    
    Details:
    - Changed the BLIS_HEAP_STRIDE_ALIGN_SIZE in the configurations from 16 to
      BLIS_CACHE_LINE_SIZE (typically 64).
    - Changed the use of nr in sizing of bd buffer to packnr in level-3 macro-
      kernels.
    - Reformulated gemm_ker_var2 to look more like the other level-3 macro-
      kernels, in that the interior and edge-case handling is expressed once
      inside the loops in the n and m dimensions, rather than the edge-case
      handling being "unrolled" and expressed as distinct code regions. The
      previous macro-kernel now lives in retired form in the subdirectory
      other/bli_gemm_ker_var2.c.old.
    - Updated experimental gemm_ker_var5 according to above change.
    - Fixed bug in bli_her2k.c whereby incorrect transformations were being
      applied to optimize the macro-kernel accesses pattern on C when C is
      row-stored.
    - Various updates inside of test/exec_sizes.

Date:   Thu Aug 1 11:24:23 2013 -0500

    Added basic OpenMP-based gemm and packm files.
    
    Details:
    - Integrated Tyler's parallelized packm_blk_var2 and gemm_ker_var2
      into the following auxiliary files
    
        frame/1m/packm/other/bli_packm_blk_var2.c
        frame/3/gemm/other/bli_gemm_ker_var2.c
    
      The routine in the first file uses a basic OpenMP parallel region to
      parallelize the packing of blocks of A and panels of B, while the
      second uses a similar parallel region to parallelize along the n
      dimension of the gemm macro-kernel.

    Added missing cpp kernel blocksize constraints.
    
    Details:
    - Added missing C preprocessor guards in bli_kernel_macro_defs.h that enforce
      constraints on the register blocksizes relative to the cache blocksizes.
      Thanks to Tyler for helping me stumble across this issue.

    Fixed minor warnings and misc issues.
    
    Details:
    - Fixed various warnings output by gcc 4.6.3-1, including removing some
      set-but-not-used variables and addressing some instances of typecasting
      of pointer types to integer types of different sizes.

    Tightened some macros that detect datatypes.
    
    Details:
    - Modified the definitions of some macros, such as bli_is_real(), so that
      the "special" bit is taken into account so that BLIS_INT is differentiated
      from BLIS_FLOAT.
    - Whitespace changes to bli_obj_macro_defs.h.
    - Removed BLIS_SPECIAL_BIT definition from bli_type_defs.h, since it wasn't
      being used.

    Added BLAS error checking to compatibility layer.
    
    Details:
    - Added frame/compat/check directory, which now houses companion _check()
      routines for each of the BLAS wrappers in frame/compat. These _check()
      routines are called from the compatibility wrappers and mimic the
      error-checking present in the netlib BLAS.
    - Edited bla_xerbla.c so that xerbla() translates the operation string to
      uppercase before printing.
    - Redefined util routines in frame/compat/f2c/util in terms of level0
      macros.
    - Added prototypes for util routines, f2c routines, lsame(), and xerbla().
    - Commented out prototypes in test/test_*.c since Fortran integers are now
      int64_t by default (and the prototypes that were present in the files
      used int).
    - Removed redundant #include "bli_f2c.h" in bli_?lamch.c and bli_lsame.c,
      since blis.h was already being included.
    - Other minor changes to code in frame/compat/f2c.

    Added support for C99 complex types/arithmetic.
    
    Details:
    - Added support for C99 complex types to bli_type_defs.h and overloaded
      complex arithmetic to the scalar-level macros in include/level0. This
      includes a somewhat substantial reorganization and re-layering of much
      of the existing machinery present in the level0 macros.
    - Added new #define for BLIS_ENABLE_C99_COMPLEX to bli_config.h files,
      commented-out by default, which optionally enables the use of built-in
      C99 complex types and arithmetic.
    - Minor changes to clarksville and reference configs' make_defs.mk files.
    - Removed macro definitions from bli_param_macro_defs.h which was not being
      used (bli_proj_dt_to_real_if_imag_eq0).

    Fixed bugs in trsm, trmm macro-kernels.
    
    Details:
    - Fixed a bug in trsm_rl_ker_var2() caused by incorrect edge case handling.
    - Fixed a bug in trsm_rl_ker_var2() and trsm_ru_ker_var2() whereby k was
      incorrectly being adjusted upward by MR, instead of NR. The rl and ru
      trmm macro-kernels were updated in a similar fashion.
    - Fixed a bug in trsm_ru_ker_var2() that was due to a missing negation on
      diagoffb when recomputing k to skip a zero region below where the
      diagonal intersects the right side of the block. The corresponding
      trmm macro-kernel was also updated.
    - Fixed a bug in trsm_ru_ker_var2() where the the adjustment of k (by NR)
      needed to be placed AFTER the block that recomputes k to skip the zero
      region (if present). The other three trsm macro-kernels, as well as the
      trmm macro-kernels, were updated in the same manner, for consistency.
    - Fixed a bug in trmm_lu_ker_var2() in which the wrong dimension (n) was
      being updated to skip a zero region to the left of where the diagonal
      of A intersects the top edge of the block.
    - Comment updates to all trsm and trmm macro-kernels.
    - Comment updates to bli_packm_init.c.

    Added f2c'ed Givens rotation wrappers.
    
    Details:
    - Retired (for now) existing ?rot*() BLAS compatibility wrappers to 'attic'
      along with other wrappers for which no BLIS implementation exists.
    - Added f2c-generated codes for applicable datatype flavors of rot, rotg,
      rotm, and rotmg operations.

      configuration. (Meant to include this in previous commit.)

    Removed copynzv, copynzm and related codes.
    
    Details:
    - Removed copynzv and copynzm operation directories. These operations
      implemented a variation of copyv/m that, in the case of real source
      and complex destination operands, leaves the imaginary component
      untouched (rather than setting it to zero). I realize now that the
      special case(s) (e.g. gemm with real A and B but complex C) that I
      thought required this operation actually can be handled more simply.
    - Removed level0 scalar macros implementing copynzs, copynzjs.

    Added handling of restrict, stdint.h for non-C99.
    
    Details:
    - Removed the #include <stdint.h> from blis.h and inserted a cpp macro block
      in bli_type_defs.h that #includes <stdint.h> for C++ and C99, and otherwise
      manually typedefs the types we need (which, for now, are unconditionally
      int64_t and uint64_t).
    - Moved basic typedefs to top of bli_type_defs.h, and comment changes.
    - Added cpp macro block to bli_macro_defs.h that #defines restrict as
      nothing for C++ and non-C99.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Mon Jul 8 15:20:34 2013 -0500

    Migrated integer usage to stdint.h types.
    
    Details:
    - Changed the way bli_type_defs.h defines integer types so that dim_t,
      inc_t, doff_t, etc. are all defined in terms of gint_t (general signed
      integer) or guint_t (general unsigned integer).
    - Renamed Fortran types fchar and fint to f77_char and f77_int.
    - Define f77_int as int64_t if a new configuration variable,
      BLIS_ENABLE_BLIS2BLAS_INT64, is defined, and int32_t otherwise.
      These types are defined in stdint.h, which is now included in blis.h.
    - Renamed "complex" type in f2c files to "singlecomplex" and typedef'ed
      in terms of scomplex.
    - Renamed "char" type in f2c files to "character" and typedef'ed in terms
      of char.
    - Updated bla_amax() wrappers so that the return type is defined directly
      as f77_int, rather than letting the prototype-generating macro decide
      the type. This was the only use of GENTFUNC2I/GENTPROT2I-related macros,
      so I removed them. Also, changed the body of the wrapper so that a
      gint_t is passed into abmaxv, which is THEN typecast to an f77_int
      before returning the value.
    - Updated f2c code that accessed .r and .i fields of complex and
      doublecomplex types so that they use .real and .imag instead (now that
      we are using scomplex and dcomplex).

    Added experimental bli_gemm_ker_var5().
    
    Details:
    - Added support for an experimental gemm macro-kernel incrementally
      packs one micro-panel of B at a time. This is useful for certain
      special cases of gemm where m is small.
    - Minor changes to default values of clarksville configuration.
    - Defined BLIS_PACKED_BLOCKS as part of pack_t type, even though we
      do not yet have any use (or implementation support) for block storage.
    - Comment update to bli_packm_init.c.

    Defined "total" blocksize query functions.
    
    Details:
    - Defined bli_blksz_total_for_type() and bli_blksz_total_for_obj() to query
      the default blocksize plus blocksize extension (using the type or the type
      of an object).
    - Comment update in bli_packm_cxk.c.

    Consolidated lower/upper her[2]k blocked variants.
    
    Details:
    - Consolidated lower and upper blocked variants for herk and her2k, and
      renamed the resulting variants, according to the same changes recently
      made to trmm and trsm.
    - Implemented support for four new subpartitions types:
        BLIS_SUBPART1T
        BLIS_SUBPART1B
        BLIS_SUBPART1L
        BLIS_SUBPART1R
      which correspond to "merged" partitions that include the middle "1"
      partition as well as either the neighboring "0" or "2" partition. This is
      used to clean up code in herk/her2k var2 that attempts to partition away
      the strictly zero region above or below the diagonal of a matrix operand
      that is being marched through diagonally.
    - Added safeguards to herk macro-kernels that skip any leading or trailing
      zero region in the panel of C that is passed in. This is now needed given
      that herk/her2k var1 no longer partitions off this zero region before
      calling the macro-kernel (via bli_her[2]k_int()).
    - Updated comments and other whitespace changes to trmm/trsm macro-kernels.

    Added row-storage optimizations for trmm, trsm.
    
    Details:
    - Implemented algorithmic optimizations for trmm and trsm whereby the right
      side case is now handled explicitly, rather than induced indirectly by
      transposing and swapping strides on operands. This allows us to walk through
      the output matrix with favorable access patterns no matter how it is stored,
      for all parameter combinations.
    - Renamed trmm and trsm blocked variants so that there is no longer a
      lower/upper distinction. Instead, we simply label the variants by which
      dimension is partitioned and whether the variant marches forwards or
      backwards through the corresponding partitioned operands.
    - Added support for row-stored packing of lower and upper triangular matrices
      (as provided by bli_packm_blk_var3.c).
    - Fixed a performance bug in bli_determine_blocksize_b() whereby the cache
      blocksize  extensions (if non-zero) were not being used to appropriately size
      the first iteration (ie: the bottom/right edge case).
    - Updated comments in bli_kernel.h to indicate that both MC and NC must be
      whole multiples of MR AND NR. This is needed for the case of trsm_r where,
      in order to reuse existing left-side gemmtrsm fused micro-kernels, the
      packing of A (left-hand operand) and B (right-hand operand) is done with
      NR and MR, respectively (instead of MR and NR).

    Use separate CFLAGS for "kernels" directories.
    
    Details:
    - Added a new "special" directory type: any source code within directories
      named "kernels" will be compiled with a separate CFLAGS_KERNELS set of
      compiler flags. This allows the developer to specify a separate set of
      flags (e.g. optimization flags) for compiling kernels while maintaining a
      standard set for regular framework code.
    - Fixed a bug in the top-level Makefile that was causing "noopt" code
      to be compiled with the standard set of compilation flags.
    - Updated make_defs.mk in reference, flame, and clarksville configurations
      according to above changes.

    Various level-3 optimizations for row storage.
    
    Details:
    - Implemented remaining two cases within bli_packm_blk_var2(), which allow
      packing from a lower or upper-stored symmetric/Hermitian matrix to column
      panels (which are row-stored). Previously one could only pack to row panels
      (which are column-stored).
    - Implemented various optimizations in the level-3 front-ends that allow more
      favorable access through row-stored matrices for gemm, hemm, herk, her2k,
      symm, syrk, and syr2k.
    - Cleaned up code in level-3 front-ends that has to do with setting target and
      execution datatypes.

    Added beta == 0 optimization to x86_64 ukernel.
    
    Details:
    - Modified x86_64 gemm microkernel so that when beta is zero, C is not read
      from memory (nor scaled by beta).
    - Fixed minor bug in test suite driver when "Test all combinations of storage
      schemes?" switch is disabled, which would result in redundant tests being
      executed for matrix-only (e.g. level-1m, level-3) operations if multiple
      vector storage schemes were specified.
    - Restored debug flags as default in clarksville configuration.

    - Fixed over-cautious handling of unaligned operands in vector instrinsic
      implementation of axpyf kernel.
    - Fixed over- and under-cautious handling of unaligned operands in vector
      intrinsic implementation of dotxaxpyf kernel.

    Details:
    - Updated level-1/-1f kernels so that non-unit and un-aligned cases are
      handled by reference implementation (rather than aborted).
    - Added -fomit-frame-pointer to default make_defs.mk for clarksville
      configuration.
    - Defined bli_offset_from_alignment() macro.
    - Minor edits to old test drivers.

    - Use BLIS_MAX_TYPE_SIZE to define BLIS_CONSTANT_SLOT_SIZE instead of
      sizeof(dcomplex).

Date:   Fri May 24 16:28:10 2013 -0500

    Fixed x86_64 kernel bugs and other minor issues.
    
    Details:
    - Fixed bugs in trmv_l and trsv_u due to backwards iteration resulting in
      unaligned subpartitions. We were already going out of our way a bit to
      handle edge cases in the first iteration for blocked variants, and this
      was simply the unblocked-fused extension of that idea.
    - Fixed control tree handling in her/her2/syr/syr2 that was not taking
      into account how the choice of variant needed to be altered for
      upper-stored matrices (given that only lower-stored algorithms are
      explicitly implemented).
    - Added bli_determine_blocksize_dim_f(), bli_determine_blocksize_dim_b()
      macros to provide inlined versions of bli_determine_blocksize_[fb]() for
      use by unblocked-fused variants.
    - Integrated new blocksize_dim macros into gemv/hemv unf variants for
      consistency with that of the bugfix for trmv/trsv (both of which now
      use the same macros).
    - Modified bli_obj_vector_inc() so that 1 is returned if the object is a
      vector of length 1 (ie: 1 x 1). This fixes a bug whereby under certain
      conditions (e.g. dotv_opt_var1), an invalid increment was returned, which
      was invalid only because the code was expecting 1 (for purposes of
      performing contiguous vector loads) but got a value greater than 1 because
      the column stride of the object (e.g. rho) was inflated for alignment
      purposes (albeit unnecessarily since there is only one element in the
      object).
    - Replaced some old invocations of set0 with set0s.
    - Added alpha parameter to gemmtrsm ukernels for x86_64 and use accordingly.
    - Fixed increment bug in cleanup loop of gemm ukernel for x86_64.
    - Added safeguard to test modules so that testing a problem with a zero
      dimension does not result in a failure.
    - Tweaked handling of zero dimensions in level-2 and level-3 operations'
      internal back-ends to correctly handle cases where output operand still
      needs to be scaled (e.g. by beta, in the case of gemm with k = 0).

    Renamed _trans_status() macro.
    
    Details:
    - Mistakenly forgot to rename the _trans_status() macro and instances in
      previous commit.

    Renamed _set_trans(), _trans_status() macros.
    
    Details:
    - Renamed the following macros:
        bli_obj_set_trans()    -> bli_obj_set_onlytrans()
        bli_obj_trans_status() -> bli_obj_onlytrans_status()
      to remove ambiguity as to which bits are read/updated.

    Unconditionally check memory pool(s) for errors.
    
    Details:
    - Changed bli_mem_acquire_m() in bli_mem.c so that we still check if the
      memory pool is exhausted before checking out and returning a block, even
      if BLIS error checking has been disabled. These errors are useful because
      they likely indicate that BLIS was improperly configured for the code
      being run.

    Absorbed blocksize extensions into main objects.
    
    Details:
    - Revamped some parts of commit b6ef84fad1c9 by adding blocksize extension
      fields to the blksz_t object rather than have them as separate structs.
    - Updated all packm interfaces/invocations according to above change.
    - Generalized bli_determine_blocksize_?() so that edge case optimization
      happens if and only if cache blocksizes are created with non-zero
      extensions.
    - Updated comments in bli_kernel.h files to indicate that the edge case
      blocksize extension mechanism is now available for use.

    Added option to disable err checking in testsuite.
    
    Details:
    - Added a new line to input.general that allows one to specify the error-
      checking level to use for each BLIS experiment. The only two levels
      supported for now are "no error checking" and "full error checking".

    Use cntl trees that block in n dimension.
    
    Details:
    - Updated _cntl.c files for each level-3 operation to induce blocked
      algorithms that first paritition in the n dimension with a blocksize
      of NC. Typically this is not an issue since only very large problems
      exceed that of NC. But developers often run very large problems, and
      so this extra blocking should be the default.
    - Removed some recently introduced but now unused macros from
      bli_param_macro_defs.h.

    Use PASTEMAC in macro-kernels (over MAC2 or MAC3).
    
    Details:
    - Replaced multi-type invocations of copys_mxn, xpbys_mxn, etc. (PASTEMAC2
      and PASTEMAC3) with those that only use a single type (PASTEMAC).
    - Added extra macros to bli_adds_mxn_uplo.h and bli_xpbys_mxn_uplo.h to
      accommodate above change.
    - Fixed comment typo in bli_config.h files.
    - Added .nfs* pattern to .gitignore.

    Fixed computation of b_next in L3 macro-kernels.
    
    Details:
    - Restructured herk_l and herk_u macro-kernels in the imagine of trmm
      and trsm, in that the edge cases are captured by the main loop, rather
      than trying to have "cleanup" sections that result in four distinct
      parts (interior, bottom edge, right edge, bottom-right edge) of the
      code.
    - Fixed the way b_next was being computed in the non-gemm level-3
      macro-kernels (herk, trmm, trsm). The way they are computed now matches
      that of gemm.

    Fixed rare edge case bug in herk_l macro-kernel.
    
    Details:
    - Fixed a potential bug in herk_l at the m_left edge case. If MR was
      chosen to be much larger than NR, then one could encounter edge cases
      in the the MC dimension that fall entirely below the diagonal, which
      the previous implementation of the herk_l macro-kernel was not allowing
      for.

Date:   Tue Apr 23 16:00:18 2013 -0500

    Added a_next, b_next arguments to micro-kernels.
    
    Details:
    - Added two more arguments to the gemm and gemmtrsm microkernels: the
      addresses of the next micro-panels of A and B. By passing these
      pointers into the micro-kernel, we allow the micro-kernel author to
      prefetch micro-panels of A and B as necessary (though this is
      completely optional; these addresses may also be safely ignored).
    - Updated all seven macro-kernels so that they compute and pass in
      a_next and b_next. Note that ONLY the gemm macro-kernel computes
      a_next and b_next with the precise semantics we want. I will go back
      and fix the other macro-kernels in the near future.
    - Added 'restrict' to various micro-kernels from which it was missing.

    Disabled:
    - Edited bli_determine_blocksize_b() to include experimental (and
      currently disabled) code that computes extended blocks.
    - Updated commnts relate to above changes.
    - Enabled use of x86 gemmtrsm ukernel in config/flame/bli_kernel.h.

    Updated dupl implementation to use PACKNR and NR.
    
    Details:
    - Updated frame/util/dupl/bli_dupl_unb_var1.c to utilize PACKNR and NR
      explicitly so navigate b1 so that situations where PACKNR > NR are
      supported.
    - Moved the 4x2 and 4x4 reference micro-kernels in frame/3/gemm/ukernels and
      frame/3/trsm/ukernels to kernels/c99/.
    - Updated clarksville and flame configurations.

    Disabled blocksize checks for memory pools.
    
    Details:
    - Temporarily disabled checks that ensure that enough memory will be allocated
      by the contiguous memory allocator for all types, given that the values for
      double precision real are the ones used to allocate the space. These checks
      can easily go awry in certain situations, especially if you are developing for
      only one datatype. So for now, they are probably more trouble than they are
      worth.

    Allow ldim of packed micro-panels != MR, NR.
    
    Details:
    - Made substantial changes throughout the framework to decouple the leading
      dimension (row or column stride) used within each packed micro-panel from
      the corresponding register blocksize. It appears advantageous on some
      systems to use, for example, packed micro-panels of A where the column
      stride is greater than MR (whereas previously it was always equal to MR).
    - Changes include:
      - Added BLIS_EXTEND_[MNK]R_? macros, which specify how much extra padding
        to use when packing micro-panels of A and B.
      - Adjusted all packing routines and macro-kernels to use PACKMR and PACKNR
        where appropriate, instead of MR and NR.
      - Added pd field (panel dimension) to obj_t.
      - New interface to bli_packm_cntl_obj_create().
      - Renamed bli_obj_packed_length()/_width() macros to
        bli_obj_padded_length()/_width().
      - Removed local #defines for cache/register blocksizes in level-3 *_cntl.c.
      - Print out new cache and register blocksize extensions in test suite.
    - Also added new BLIS_EXTEND_[MNK]C_? macros for future use in using a larger
      blocksize for edge cases, which can improve performance at the margins.

    Fixed bug in compatibility layer (her2k/syr2k).
    
    Details:
    - Fixed a bug in the BLAS compatibility layer, specifically in bla_her2k.c
      and bla_syr2k.c, that caused incorrect computation to occur when the BLAS
      interface caller requests the [conjugate-]transpose case. Thanks to Bryan
      Marker for reporting the behavior that led to this bug.

    Changed old level3 test drivers to call front-ends.
    
    Details:
    - Changed old level-3 test drivers, in 'test' directory, to always call the
      front-end object API instead of the internal back-end with the locally
      defined control tree.

    Allow packm_init() to reacquire a too-small mem_t.
    
    Details:
    - Changed bli_packm_init() to react differently to a situation where a pack
      obj_t has an already-allocated mem_t entry that has a buffer that is smaller
      than what will be needed to hold the block/panel that now needs to be
      packed. Previously, this situation was treated with an abort() since I
      assumed something was horribly wrong. I have changed the code so that it now
      reacts by releasing the previous mem_t and re-acquires a new mem_t with the
      new information. (This change was done at the request of Bryan Marker to
      facilitate code generation via DxT.)

    Fixed bug in packing block of A for hemm/symm.
    
    Details:
    - Fixed a bug in bli_packm_blk_var2() that affected the packing functionality
      of hemm and symm. The bug occurs whenever attempting to pack a Hermitian or
      symmetric matrix where the block of A being packed intersects the diagonal,
      but some of its micro-panels do not intersect the diagonal and lie completely
      in the unstored region. Thanks to Francisco Igual for reporting this bug.
    - Comment updates to both _blk_var2.c and _blk_var3.c.

    Activated bli_packm_acquire_mpart_t2b().
    
    Details:
    - Removed the overly-paranoid bli_abort() from the end of
      bli_packm_acquire_mpart_t2b(), to allow others to experiment with
      partitioning through packed blocks of A. Also, and more importantly,
      changed an earlier check that was causing an erroneous (but
      coincidentally redundant) abort(). Also, updated some of the comments
      in bli_packm_part.c.

    Allow creation of "empty" objects.
    
    Details:
    - Modified bli_obj_alloc_buffer() to allow allocating an empty buffer, and
      modified bli_adjust_strides() to explicitly handle m = n = 0.
    - Updated bli_check_matrix_strides() to allow cases where m = n = 0.

    Fixed "root" object bug in bli_her[2]k/syr[2]k.
    
    Details:
    - Fixed an obscure bug in the front-ends for herk, her2k, syrk, and syr2k,
      that manifested as the incorrect triangle being updated. It occurred when
      the user would pass in a matrix object that was correctly marked as
      symmetric/Hermitian and lower-stored, but whose root object was never marked
      as lower (or upper). We now alias and re-assign root status for matrix C
      within the front-ends. Note that trmm and trsm were already doing this,
      albeit for a slightly different reason (to allow the internal back-end to
      choose which algorithm to run--lower or upper--based on the uplo of the root
      object for both left and right side cases). Thanks to Bryan Marker for
      leading me to this bug.

    Fixed overzealous type-checking in bli_getsc().
    
    Details:
    - Relaxed type checking in getsc so that the input object could be a constant
      and not just a proper floating-point type. (If it is a constant, default to
      extracting the dcomplex values.) Thanks to Bryan Marker for reporting this
      bug.
    - Added definition for bli_is_constant() in bli_param_macro_defs.h
    - Comment updates to various level-0 scalar routines.

    Fixed bug in bli_obj_is_packed() and renamed.
    
    Details:
    - This macro is used to determine whether the partitioning routines should
      call a corresponding packm_part routine instead. However, it was
      unintentionally catching matrices that were marked as "packed" by virtue
      of them simply being marked as BLIS_PACKED_UNSPEC in, say, bli_gemv().
      The macro has now been renamed to bli_obj_is_panel_packed(), and now only
      checks for row or column panel packing. (Note that I first attempted to
      fix this bug in a571af816d72.) Thanks to Bryan Marker for reporting the
      erroneous behavior that led me to this bug.

    Tweak to test suite function string construction.
    
    Details:
    - Fixed a minor bug in the way that the test suite would construct function
      name strings when the user anchored all parameters in input.operations.
      In this case, the test driver would mistake this situation for one where
      the operation simply had no parameters to begin with, and thus would not
      include the parameter string in the function string that is output for
      every result.

    Modified bli_kernel.h include order in blis.h.
    
    Details:
    - Delayed #include of bli_kernel.h in blis.h to prevent a situation where
      _kernel.h includes an optimized microkernel header, which uses BLIS types
      such as dim_t and inc_t, which would precede the definition of those types
      in bli_type_defs.h.
    - Moved the #include of bli_kernel_macro_defs.h in bli_macro_defs.h to blis.h
      (immediately after that of bli_kernel.h).

    - Modified gemmtrsm micro-kernel wrappers to use new aliased blocksize macros
      instead of operation-specific ones.
    - Removed local, gemmtrsm-specific blocksize macro definitions found in

    Added/renamed alignment constants to _config.h.
    
    Details:
    - Added new memory alignment constants:
        BLIS_HEAP_STRIDE_ALIGN_SIZE   (previously assumed to be same as SYSTEM_MEM)
        BLIS_CONTIG_ADDR_ALIGN_SIZE   (previously assumed to be same as PAGE_SIZE)
        BLIS_STACK_BUF_ALIGN_SIZE     (previously not enforced)
      and renamed existing ones
        BLIS_SYSTEM_MEM_ALIGN_SIZE -> BLIS_HEAP_ADDR_ALIGN_SIZE
        BLIS_CONTIG_MEM_ALIGN_SIZE -> BLIS_CONTIG_STRIDE_ALIGN_SIZE
      to better convey what the alignment factor is used for (and what it is
      not used for).
    - Removed BLIS_ENABLE_SYSTEM_MEM_ALIGN. Dynamic memory alignment is now
      disabled by setting BLIS_HEAP_STRIDE_ALIGN_SIZE to 1.
    - Inserted instances of __attribute__((aligned(BLIS_STACK_BUF_ALIGN_SIZE)))
      into macro-kernels to specify stack alignment of temporary buffers.
    - Modified test suite driver to output new constants.
    - Removed bli_align_dim_to_sys() and bli_align_dim_to_cmem(). Instead, we now
      use bli_align_dim_to_size(), which takes a third argument (the desired
      alignment).

    Fixed an bug in axpyv/axpym when alpha is unit.
    
    Details:
    - Fixed bug whereby axpyv and axpym were incorrectly simplifying to a copy,
      rather than an add, when alpha = 1. Thanks to Bryan Marker for identifying
      this bug.

    Moved _POSIX_C_SOURCE def to compiler cmd line.
    
    Details:
    - Removed the #define of _POSIX_C_SOURCE in bli_config.h (for both reference
      and clarksville configurations) and added "-D_POSIX_C_SOURCE=200112L" to
      the compiler command line arguments in make_defs.mk (for both configs).
      Thanks to Devin Matthews for suggesting this change.

    Appended 'f2c_' to abs, min, max macros in f2c.h.
    
    Details:
    - Renamed abs, min, max, dmin, and dmax macros in bli_f2c.h so that they
      would not conflict with anything defined by the user (or the language).
      Thanks to Devin Matthews for suggesting this fix.
    - Updated all instances of the above macros accordingly.

    Added new kernel blocksize macro aliases.
    
    Details:
    - Added new macros that alias level-3 cache and register blocksize macros
      to names that can be constructed via the PASTEMAC macro. These aliased
      macro definitions live inside bli_kernel_macro_defs.h, which is now
      #included after bli_kernel.h.
    - Modified macro-kernels to use new aliased blocksize macros instead of
      operation-specific ones.
    - Removed local, operation-specific kernel blocksize macro definitions
      (found in macro-kernel header files).

    Reverted testsuite object files' home to 'obj'.
    
    Details:
    - Removed 'obj' and 'lib' from .gitignore.
    - Added testsuite/obj/.gitkeep (which is an empty file).
    - Updated testsuite/Makefile accordingly.
    - Thanks to Vernon Austel for pointing out the .gitkeep trick to tracking
      empty directories in git.

    Details:
    - Replaced scalar constant macro definitions in bli_const_defs.h with a single,
      simplier macro in bli_obj_macro_defs.h.
    - Updated invocations of old macros accordingly.
    - Removed bli_const_defs.h.

    Fixed a performance bug in trsm.
    
    Details:
    - Fixed a bug in the reference implementations of the gemmtrsm wrappers
      (bli_gemmtrsm_l_ref_mxn.c and bli_gemmtrsm_u_ref_mxn.c) whereby the
      reference gemm microkernel was hard-coded, and thus always called, even
      when GEMM_UKERNEL was defined to point to an optimzied microkernel. This
      manifested as artificially low trsm performance for all problem sizes, but
      especially for small problem sizes as it only affected blocks of A that
      intersected the diagonal. Thanks to Mike Kistler of IBM for helping me
      find this bug.

    Generate testsuite objects 'src'.
    
    Details:
    - Tweaked the testsuite makefile so that object files are stored in 'src'
      rather than 'obj', since (a) the top-level .gitignore dictates that
      obj directories are to be ignored, and (b) since git has problems
      tracking empty directories. Now, users do not need to create their own
      obj directories within their own local clones of BLIS.

    Fixed definition of bli_is_packed_object() macro.
    
    Details:
    - Changed the definition of bli_is_packed_object() so that it keys off of the
      value of the pack schema bits in the info field of obj_t, rather than
      comparing the obj_t buffer with that of the mem_t entry. This was the cause
      of a very low probability bug whereby uninitialized memory caused the macro
      to evaluate to TRUE even though the object in question was not packed.
      Thanks to Vernon Austel of IBM for helping discover this bug.
    - Changed an abort() in bli_packm_part() to a not-yet-implemented.

    Fixed edge case handling bug in herk macrokernels.
    
    Details:
    - Fixed a bug present in bli_herk_l_ker_var2() and bli_herk_u_ker_var2() that
      only manifests when BLIS is configured such that MR != NR. The bug involves
      incorrectly detecting edge cases, which resulted in some parts of matrix C
      potentially being skipped and not updated, depending on the problem size.
    - Updated the default values of MR and NR in config/reference/bli_kernel.h to
      8 and 4, respectively, so that I can better stress the framework on a
      day-to-day basis. (The fact that they were both equal to 4 for so long is
      why I did not stumble upon this bug much sooner.)

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Thu Apr 4 15:25:43 2013 -0500

    Added reference microkernels for arbitrary MR, NR.
    
    Details:
    - Added a new set of reference gemm, gemmtrsm, and trsm micro-kernels that
      contain explicit loops over MR and NR, thus allowing them to be used
      unmodified by developers who want to build a reference library with
      custom register blocksizes.
    - Changed config/reference/bli_kernel.h to use above ukernels by default.
    - Changed interfaces of new and existing gemm, gemmtrsm, and trsm micro-kernels
      to use 'restrict' keyword.
    - Added -funroll-loops option to config/reference/make_defs.mk.
    - Updated comments in bli_kernel.h describing constraints on register and
      cache blocksizes.
    - Updated _adds_mxn.h, _copys_mxn.h, and _xpbys_mxn.h macros files so that
      single-char macros are also defined.

    - Activated BLAS2BLIS routine mapping for new amax BLIS implementation.
    - Added integer support to [f]printv, [f]printm.
    - Added integer support to level-0 copys macros.
    - Updated printing of configuration information in test suite driver.
    - Comment changes to _config.h files.

    More memory alignment-related tweaks.
    
    Details:
    - Renamed BLIS_MEMORY_ALIGNMENT_SIZE to BLIS_CONTIG_MEM_ALIGN_SIZE.
    - Renamed BLIS_ENABLE_MEMORY_ALIGNMENT to BLIS_ENABLE_SYSTEM_MEM_ALIGN.
    - Added BLIS_SYSTEM_MEM_ALIGN_SIZE, which controls only the alignment
      passed into posix_memalign() or equivalent.
    - Defined new function, bli_align_dim_to_cmem(), which applies the
      contiguous memory alignment (rather than the system/malloc alignment).

    Always define memory alignment size cpp constant.
    
    Details:
    - Removed guard around #define for memory alignment size constant.
      Memory alignment should always be enabled, and so this value should
      always be defined.

    Align packed panel strides with system alignment.
    
    Details:
    - Pass panel strides through bli_align_dim_to_sys() to ensure that each
      subsequent packed panel of A and B begins at an aligned address. (The
      first panel is presumably aligned to system alignment because it is
      aligned to a page boundary, which is typically much larger.)
    - Rearranged code in packm_init_pack() to prevent additional conditional
      blocks as a result of the aforementioned change.
    - Adjusted contiguous memory allocator so that the system memory alignment
      is used to allocate enough space for each block no matter what kind of
      register blocking is used (even if register blocksize is unit and every
      row/column needs maximal padding).
    - Adjusted default blocksizes in reference configuration so that MC*KC
      and KC*NC result in identical footprints for all datatypes.

    Removed #include "blis2.h" from low-level headers.
    
    Details:
    - Removed #include of "blis2.h" from various lower-level, operation-specific
      header files throughout the framework. Given that these low-level headers
      are included within #blis2.h in a very specific order, #include'ing blis2.h
      within them directly is unnecessary.

    Added cpp guards to conflicting libflame typedefs.
    
    Details:
    - Added cpp guards around the definitions of dim_t, scomplex, and dcomplex.
      This is a temporary hack to allow interoperability with libflame. (Similarly
      temporary changes are being made to libflame's type definitions file.)

    Details:
    - Renamed BLIS_MAX_PREFETCH_BYTE_OFFSET to
      BLIS_MAX_PRELOAD_BYTE_OFFSET since "prefetch" is kind of a loaded word
      (e.g. "prefetch" instructions, which are different than the particular

    Relocated packed mem_t dimension fields to obj_t.
    
    Details:
    - Removed the m and n (and elem_size) fields from the mem_t object, and added
      m_packed and n_packed fields to obj_t. These new fields track the same as
      the old ones. From an abstraction standpoint, it seemed awkward to store
      those dimensions inside the mem_t.
    - Updated interfaces to bl2_mem_acquire_*() so that only a byte size argument
      is passed in, instead of m, n, and elem_size.
    - Updated bl2_packm_init_pack() and bl2_packv_init_pack() to inline the
      functionality of bl2_mem_alloc_update_m() and bl2_mem_alloc_update_v(),
      respectively.
    - Updated packm variants to access the packed length and width fields from
      their new locations.

    Re-implemented contiguous memory allocator.
    
    Details:
    - Completely re-wrote the contiguous memory allocator (bl2_mem.c). The new
      allocator instantiates and initializes three separate memory pool objects,
      each one associated with a separate array of contiguous memory blocks, each
      block of fixed and uniform size. (The three pools are for allocating mc-by-kc
      blocks of A, kc-by-nc panels of B, and mc-by-nc panels of C.) The pool
      objects use a stack structure internally to track which blocks in the region
      have been "checked out" to a thread and which are still available. Critical
      regions are now clearly marked and adaptable to parallel environments (e.g.
      OpenMP). Memory pools are set up when bl2_init() is called.
    - Added a new field to the packm control tree node, which indicates what kind
      of packed buffer is being allocated. The enumerated type for this argument
      is defined as packbuf_t in bl2_type_defs.h.
    - Updated level-3 _cntl.c files to pass in the appropriate value for a new
      packbuf_t argument to bl2_packm_cntl_obj_create().
    - Moved some macros called by packm_init_pack() from bl2_obj_macro_defs.h to
      bl2_mem_macro_defs.h.
    - Added BLIS_MAX_NUM_THREADS to bl2_config.h, which we use as the default
      number of blocks of A reserved for the memory allocator.
    - Deprecated bl2_align_dim(). Replaced usage with that of
      bl2_align_dim_to_mult(). Turns out that typically we don't need to align
      a dimension to the system alignment, since that value has to do with
      starting addresses, whereas the values we are dealing with are unitless
      dimensions.

    Perform her2k var1 loops in sequence.
    
    Details:
    - Changed variant 1 of her2k so that the two rank-k products are computed
      and accumulated in sequence rather than fused into one loop. This is
      necessary if BLIS is to be configured to provide only enough contiguous
      memory for one panel of B.

    Enhanced tracking of dimensions for mem_t objects.
    
    Details:
    - Added new fields to mem_t struct definition to track the allocated (as
      opposed to the currently used) dimensions of the memory region. This
      allows packm_init() to be more robust in situations where memory is
      already allocated but is more than needed for the current packing job.
    - Updated logic in bl2_obj_set_buffer_with_cached_packm_mem() macro, used
      in packm_init(), to update the "currently used" dimensions of the mem_t
      object if the requested dimensions are smaller than the allocated
      dimensions.

    Updated behavior of bl2_obj_induce_trans() macro.
    
    Details:
    - Changed bl2_obj_induce_trans() so that the transposition bit is no longer
      updated as part of the macro. All current uses of the macro have been
      coupled with instances of bl2_obj_set_trans() to clear the bit.
    - Added Jed to CREDITS file.

    Replaced banded/packed BLAS2 stubs with f2c code.
    
    Details:
    - Retired the blas2blis wrappers that simply called abort with a "not yet
      implemented" message. This includes all of the level-2 banded and packed
      routines.
    - Replaced the aforementioned with the corresponding netlib implementations
      having been run through f2c (with some customization).
    - Added directories named 'attic' to build/gen-make-frags/ignore_list.

    Moved Fortran name-mangling macro to bl2_config.h.
    
    Details:
    - Moved the Fortran-77 name-mangling macros from bl2_blas_macro_defs.h to the
      configuration directory (bl2_config.h, specifically) given that it can be
      expected to be tweaked by some developers.

    Implemented blas2blis compatibility layer.
    
    Details:
    - Added the blas2blis compatibility layer, located in frame/compat. This
      includes virtually all of the BLAS, including banded and packed level-2
      operations.
    
    - Defined bl2_init_safe(), bl2_finalize_safe(). The former allows a conditional
      initialization, which stores the "exit status" in an err_t, which is then
      read by the latter function to determine whether finalization should actually
      take place.
    - Added calls to bl2_init_safe(), bl2_finalize_safe() to all level-2 and
      level-3 BLAS-like wrappers.
    - Added configuration option to instruct BLIS to remain initialized whenever
      it automatically initializes itself (via bl2_init_safe()), until/unless the
      application code explicitly calls bl2_finalize().
    
    - Added INSERT_GENTFUNC* and INSERT_GENTPROT* macros to facilitate type
      templatization of blas2blis wrappers.
    - Defined level-0 scalar macro bl2_??swaps().
    - Defined level-1v operation bl2_swapv().
    - Defined some "Fortran" types to bl2_type_defs.h for use with BLAS
      wrappers.

    Fixed some scalar types in BLAS-like Herm APIs.
    
    Details:
    - Some of the scalars of Hermitian operations, such as alpha in her,
      alpha and beta in herk, and beta in her2k, need to be real. These
      arguments were typed incorrectly as the complex types. This has been
      fixed. Note the issue was only present in the BLAS-like APIs for
      these operations (not the native object-based interfaces).

    Changed API of packm_init_pack() to use blksz_t.
    
    Details:
    - Changed the interface of packm_init_pack() so that mult_m and mult_n
      are passed in as type blksz_t* instead of dim_t.
    - Make similar change for packv_init_pack().

    Minor changes to lower levels of scalm and setm.
    
    Details:
    - Removed diagx parameter from lower-level interfaces of scalm.
    - Modified scalm_basic_check() to expect an object with a nonunit diagonal.
    - Changed setm_unb_var1() so that having an implicit unit diagonal results
      in only the strictly lower or upper triangle of the matrix being modified.

    - Updated beta == zero semantics of mulsc. Hopefully this is the last
      operation that needed updating.
    - Added Devin to CREDITS file.

    Removed some calls to setv() in test modules.
    
    Details:
    - Removed calls to setv() in test modules whose sole purpose was to
      initialize vectors to zero to ensure that nan's and inf's would not
      taint the computation. Now that beta == zero semantics have been
      updated to clear the output operand (when beta is zero), rather than
      multiply against it, these setv() calls are no longer needed.

    Properly implemented beta == 0 semantics.
    
    Details:
    - Changed name of set0 and set0_mxn macros to set0s and set0s_mxn,
      respectively.
    - Added code to the following operations that sets the output operand to
      zero if the corresponding scalar is zero (rather than performing the
      floating-point multiply, or in the case of setv, copying the value).
      This will prevent nan's and inf's from creeping into results from
      uninitialized memory.

    Fixed stale interface to packm_unb_var1().
    
    Details:
    - Removed the control tree from the interface to packm_unb_var1(), which
      I meant to do when it was un-deprecated.

    Un-deprecated packm_unb_var1.c (needed by l2 ops).
    
    Details:
    - Added bl2_packm_unb_var1() back into the mix once I realized that level-2
      operations still need this routine for packing matrices. Now, whether
      level-2 operations should be packing matrices to begin with is another
      matter. But this fixes the segmentation fault one would have gotten when
      running bl2_gemv() on a general stride matrix.

    Removed cntl tree usage from packm implementation.
    
    Details:
    - Added new fields to obj_t info field:
      - invert_diag
      - pack_order_if_upper
      - pack_order_if_lower
      These fields allow packm_init() to embed information that begins
      in the control tree into the object so that the packm implementation
      does not need to use control trees at all. This is being done to aid
      Bryan's DxT code generation.
    - Added macros that operate on above fields.
    - Changed packm_init(), packm_blk_var2(), and packm_blk_var3() according
      to above changes.
    - Made similar (but much simpler) changes to packv.
    - Deprecated packm_blk_var1(), packm_unb_var1(), and packm_densify().
      These were part of prototype implementations and are no longer needed.

Author: Field G. Van Zee <field@cs.utexas.edu>
Date:   Mon Feb 11 13:20:44 2013 -0600

    Added unified test suite, and many fixes.
    
    Details:
    - Added a highly configurable, unified test suite.
    
    - Removed DUPB configuration constant from bl2_kernel.h and macro-kernel
      header files. Now, instead, DUPB is computed as (NDUP != 1) within each
      macro-kernel. This fixes a bug in trmm/trsm whereby bp was indexed into
      incorrectly when DUPB was set to FALSE but the NDUP was still non-unit.
      By encoding both pieces of information into one constant in _kernel.h,
      it seems somewhat less likely others will encounter this bug in the
      future.
    - Added level-2 cache blocksizes to _kernel.h for reference configuration,
      and defined blocksizes in _cntl.c files to these default values.
    
    - Changed semantics of her2k and syr2k such that these operations no longer
      expect the B matrix to already be conjugate-transposed (or just transposed
      for syr2k). However, these semantics are preserved for the internal
      mechanics of the implementations, including the internal back-end and all
      blocked variants.
    - Inserted checks for real-valued alpha and beta for herk/her2k and herk,
      respectively.
    
    - Relaxed general object structure constraints in _basic_check() for gemv, ger.
    - Changed her front-end to NOT copy-cast to real projection; instead, this is
      replaced by selecting either the real part or both parts within the unblocked
      algorithm implementation, depending on the value of conjh.
    - Added conjh to all _check routines for her so that the code knows when to
      verify that alpha has an imaginary component equal to zero (for her, but
      not syr).
    - Changed control tree for her to forgo packing.
    
    - Added unit diagonal support to fnormm.
    - Redefined real versions of abval2s macros in terms of fabs(), fabsf().
    - Redefined complex versions of sqrt2s macros using the actual "complex square
      root" formula.
    - Created new level-0 object-based routines, suffixed with "sc" (for "scalar").
    - Defined new level-1v, -1d, and -1m versions of add and sub operations
      (two-operand add and subtract).
    - Added new scalar macros:
      - getris: acquire real and imaginary components.
      - setris: set real and imaginary components.
      - addjs: addition with conjugated x.
      - subjs: subtraction with conjugated x.
    - Defined new utility operations:
      - absumv: element-wise sum of absolute values for vector elements.
      - absumm: element-wise sum of absolute values for matrix elements.
      - mkherm: convert existing matrix to Hermitian.
      - mksymm: convert existing matrix to symmetric.
      - mktrim: convert existing matrix to triangular.
    
    - Added various error checking routines.
    - Added bl2_clock_min_diff(), which is used to more cleanly measure the
      wall clock time of a code block.
    - Added general stride support to bl2_obj_alloc_buffer().
    - Added bl2_obj_init_scalar().
    - Updated parameter mapping in bl2_param_map.c.
    - Added support for queriable version string.
    
    - Fixed a bug in the her2k macro-kernels (which currently are simply
      implemented in terms of two invocations of herk) whereby beta was being
      applied to both the first and second rank-k updates, rather than only
      the first.
    - Fixed a bug in trmm/trsm whereby transpose and right side cases were not
      properly implemented due to erroneous assumptions regarding aliasing and
      root objects.
    - Fixed a bug in the upper triangular trsm macro-kernel in which the wrong
      MR x NR block of B was being updated.
    - Fixed a bug in the inverts macro in the double real case whereby the
      value was typecast to float before inversion. This affected non-unit cases
      of dtrsm.
    - Fixed a bug in the reference kernels for gemmtrsm whereby the minus one
      constant was being applied incorrectly.
    - Fixed a bug in the overall treatment of non-unit alpha for trsm. The code
      now mimics the rank-k strategy of gemm, whereby alpah is applied during
      the first iteration of variant 3, with BLIS_ONE passed in instead for
      subsequent iterations. This also required passing alpha into the macro-
      kernels as well as the fused gemmtrsm micro-kernels.
    - Fixed a bug in trsm_u_blk_var1 whereby the gemm macro-kernel was being
      called for blocks strictly above the diagonal. While this sounds good in
      theory, this cannot be done because gemm_ker_var2 expects row panels of
      A to be packed from top to bottom, while for trsm_u, A is actually packed
      from bottom to top due to the reverse (BR->TL) nature of the algorithm.
    - Fixed a bug in packm_cxk() whereby panel packings with unit panel
      dimensions were mishandled due to incorrect arguments to the copyv kernel.
      Also changed the copyv kernel invocation to scal2v so that these edge
      cases are properly handled when scaling is requested.
    - Fixed a bug in packv_int() whereby an uninitialized object is passed in
      instead of the source object.
    - Fixed a bug whereby level-2 code could allocate memory dynamically via
      bl2_malloc() and then attempt to free it via bl2_mm_release(). Also fixed
      a potential future bug whereby a mem_t object that is actually no longer
      "allocated" from the static pool is mistaken for being allocated due to
      failure to NULLify the buffer when the block was most recently released.
    - Fixed a bug in bl2_acquire_mpart_*() whreby the uplo field was mistakenly
      toggled when the requested subpartition needed to be "reflected" due to it
      residing in an unstored region.

    Defined Frobenius norm operations.
    
    Details:
    - Added level-0 grabis macro operation to grab imaginary component of one
      variable and copy it to the real component of another variable.
    - Defined sumsqv operation, which computes the sum of the absolute squares
      of the elements of a vector. This implementation is modeled after ?lassq
      in netlib LAPACK.
    - Defined fnormv and fnormm operations, which compute the Frobenius norm on
      vectors and matrices, respectively. These operations are treated as one-
      operand operations where the output norm value is the real projection of
      the datatype of the input operand. Both operations are implemented in terms
      of sumsqv.

    Details:
    - Added function and prototype macro-generating macros for GENTFUNCR and
      GENTPROTR, which are one-operand macros with auxiliary real projection
      types.
    - Tweaked bl2_machval files to use new macros.

    Details:
    - Fixed some inconsistent usage of n_iter_max and n_iter in the two
      bl2_set_dims_incs_uplo_[12]m macros. The right thing ended up happening
      despite the bug, which is why I had not discovered it until now.

    Renamed x86,x86_64 kernels to indicate 'd' fusing.
    
    Details:
    - Renamed x86 and x86_64 kernels to contain a 'd' before the fusing shape
      to emphasize that the fusing shape is not for all datatype instances, but
      rather just for one (that of double-precision real). Other fusing shapes
      would be proportional to their precision and domain "byte footprints".
    - Corresponding changes to config/clarksville/bl2_kernel.h.

    More tweaks to _config.h, _kernel.h; smem tweaks.
    
    Details:
    - Moved kernel-related definitions form bl2_config.h to bl2_kernel.h.
    - Replaced #define of _GNU_SOURCE with #define of _POSIX_C_SOURCE. This
      accomplishes the same thing (enabling posix_memalign()) without enabling
      all of the GNU extensions we don't need.
    - Defined the size of the static memory pool in terms of MC, KC, and NC,
      as well as two new constants that determine how many MCxKC blocks and
      how many KCxNC blocks should be allocated (defined in bl2_config.h).
    - In the case of static memory pool exhaustion, replaced the generic
      bl2_abort() with a specific error code call.

    Details:
    - Added 10xk, 12xk, 14xk, and 16xk reference kernels for packm and
      unpackm.
    - Updated bl2_[un]packm_cxk() to silently use scal2m if "out of range"
      kernel size is requested. (Thanks to Tyler for finding this bug.)
    - Updated bl2_kernel.h to contain new _KERNEL definitions, according
      to above changes, for 'reference' and 'clarksville' configurations.
    - Updated CHANGELOG.
    - Removed "output*.m" from .gitignore.

    Added auto-detection of version string (via git).
    
    Details:
    - Added build/update-version-file.sh script for auto-detecting "version"
      string and updating 'version' file accordingly. (If .git directory is
      not present, then it is assumed this copy of BLIS is a downloaded
      release, in which case 'version' file is left unchanged.)
    - Added invocation of update-version-file.sh to configure script.
