53a9ab1c85 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_M_THREAD_RATIO -> BLIS_THREAD_RATIO_M
    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.

c92762ecdc 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.

ac18949a4b 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*().

c03728f1f4 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.

e249a00a82 Imported skx dgemm ukernel from skx-redux branch.
Details:
- Added the new bli_dgemm_skx_asm_16x14.c microkernel from the skx-redux
  branch, along with appropriate blocksizes in bli_cntx_init_skx.c and
  a prototype in bli_kernels_skx.h. (Devin has not yet written the
  sgemm analague, so for now we will continue using the older sgemm
  ukernel.)
- Updated frame/include/bli_x86_asm_macros.h with a minor change that
  was present within the skx-redux branch.

fb81c7fc66 Defined cortexa53 sub-configuration.
Details:
- Added a new sub-configuration 'cortexa53', which is a mirror image
  of cortexa57 except that it will use slightly different compiler
  flags. Thanks to Mathieu Poumeyrol for making this suggestion after
  discovering that the compiler flags being used by cortexa57 were
  not working properly in certain OS X environments (the fix to which
  is currently pending in pull request #245).

10d07357af 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.

0f491e994a 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.

4f6745d68a 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.

017548314f 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.

b7db293323 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).

ecbebe7c2e 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.

3ee2bc0f7a 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).

e88aedae73 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.

* Upload artifacts

* Fix install in appveyor

* Remove windows.h in bli_winsys.c (#229)

Looks like it is unneeded.

* Implemented ARG_MAX hack in configure, Makefile.

Details:
- Added support for --enable-arg-max-hack to configure, which will
  change the behavior of make when building BLIS so that rather than
  invoke the archiver/linker with all of the object files as command
  line arguments, those object files are echoed to a temporary file
  and then the archiver/linker is fed that temporary file via the @
  notation. An example of this can be found in the GNU make docs at
  https://www.gnu.org/software/make/manual/make.html#File-Function
- Thanks to Isuru Fernando for prompting this feature.

- Added functions to bli_obj_macro_defs.h to get and set the target
  domain and target precision bits in the obj_t, and also added the
  appropriate support in bli_type_defs.h.

e88a5b8da8 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.

87db5c048e 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.

65fae95074 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.

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).

0a4a27e1a4 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.

22deef2f54 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.

5140ee3424 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.

12dfa95164 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.

    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_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()

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

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.
