commit 0680916fdd532f7a4716b11a2515243b2c08d00f (HEAD, tag: 0.0.9, origin/master, origin/HEAD, master)
commit 089048d5895a30221b6b1976c9be93ad6443420d (HEAD, tag: 0.1.0, origin/master, master)
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Nov 9 17:18:00 2013 -0600
Added object wrappers to 1f test suite modules.
Details:
- Added missing object wrappers to level-1f test suite modules. This was
only apparent if you were configuring with something other than the
reference configuration.
- 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.
- Whitespace changes to template micro-kernels.
- Comment changes to template level-1f kernel headers.
commit 9ef3752079de10124bed906b5d28479d04aa8187
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Nov 8 17:20:47 2013 -0600
Updated template kernels wrt KernelsHowTo wiki.
Details:
- Merged latest state of KernelsHowTo wiki into template micro-kernels
located in config/template/kernels/3.
commit 376bbb59c8944e29c5c1ff6637920d8451370afa
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Nov 8 11:17:34 2013 -0600
Removed support for duplication.
Details:
- Removed support for duplication from the gemmtrsm/trsm micro-kernels
and all framework code.
- Updated test suite modules according to above changes.
commit 68a5910974b62b4df853fae2a68cb04df9d5a19c
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Nov 7 11:36:11 2013 -0600
Added comments to testsuite/input.operations.
Details:
- Added extensive comments to the top of testsuite/input.operations,
which describe how to edit the file.
- Removed input.operations.0 and input.operations.1.
- Changed input.general to test all datatypes ("sdcz") by default.
commit a98f78b715fb256a519870071bb5266130d70b21
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Nov 6 15:32:47 2013 -0600
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.
commit 1f8afc3e08a4312cfe810be86aedeacbc57275c5
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Nov 6 10:09:10 2013 -0600
Minor comment update to BLAS compat files.
commit 1abbf768afafc158d44e4d5c4a135cfd9e277f13
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Nov 4 15:50:00 2013 -0600
Fixed bugs in scalv and setv.
Details:
- Fixed bugs similar to those addressed in cca1e1f51dc6, whereby
a segmentation fault may occur if beta is not the same type as
the vector operand for scalv and setv.
- Changed axpyv and scal2v front-ends in a similar fashion.
commit f5953259a1842ee48e5833c22ac86e68a337bfe1
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Nov 4 14:43:55 2013 -0600
Fixed a bug related to Hermitian matrix diagonals.
Details:
- Fixed a bug whereby BLIS assumed that the imaginary components of the
diagonal elements of Hermitian matrices were already zero. This property
is now enforced when the matrix is packed (bli_packm_blk_var2). Thanks
to Vladimir Sukharev for reporting this bug.
- Minor comment updates to template kernels.
commit d70f2b089dac8b9e4c19295dfa6014c36afee2ec
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Sat Nov 2 17:19:40 2013 -0500
Added scaling to abval2s, sqrt2s macros.
Details:
- Re-defined abval2s and sqrt2s macros to use scaling to avoid underflow
and overflow from squaring the real and imaginary components. (This is
the same technique used to fix recent bugs in invscals/invscaljs and
inverts.)
commit c5b1ed9409ae2f71d04041eef5da9a0080b5784a
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Nov 1 10:28:04 2013 -0500
Added new dotxaxpyf variant 2.
Details:
- Added a new variant for dotxaxpyf that is based on dotxf and axpyf
kernels. By default, this variant is not used by any other operation.
commit 97f89fbcf202d72fc440b614708e352ea31633e2
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Nov 1 10:16:39 2013 -0500
Fixed bug in complex invscals.
Details:
- Fixed complex inversion in invscals and invscaljs whereby the
imaginary component was being computed incorrectly.
- Use bli_fmaxabs() instead of bli_fabs() when choosing the scalar
in inverts, invscals, and invscaljs.
- Changed bli_abs() and bli_fabs() macro definitions to use "<="
operator instead of "<".
commit eda42a21d17a2742eab69ab801ed530b82488c8a
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 31 18:00:44 2013 -0500
Defined missing symbols in bla_rotg.c
Details:
- Defined local equivalents of libf2c's r_sign(), d_sign(), c_abs(), and
z_abs(), which are needed by bla_rotg.c. Also defined r_abs() and
d_abs() for completeness. Thanks to Vladimir Sukharev for reporting
these bugs.
commit cca1e1f51dc67a2c3725d5c1837256831aaf70f8
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Oct 30 14:39:01 2013 -0500
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.
commit 2807013a4761c2b84b3944de64d23483ad7ef2fb
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 24 14:32:20 2013 -0500
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.
commit 45a80c625f84edb2ade6ac25efe2b9c589d7e0df
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Oct 23 12:15:25 2013 -0500
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.
commit a091a219bda55e56817acd4930c2aa4472e53ba5
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Oct 14 10:11:29 2013 -0500
Minor fixes to piledriver configuration, ukernel.
Details:
- Applied a patch from Tyler that fixes minor staleness in the piledriver
configuration and gemm micro-kernel.
- Very minor changes to test suite input files.
commit dacdde27aee4fb90b14880136d7f20c6b234e2c6
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Oct 11 11:37:19 2013 -0500
Added Fran's Sandy Bridge kernels/configuration.
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.
commit 03106d650e4030d4c9831683448376f92fc52d41
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Oct 11 10:40:38 2013 -0500
Fixed minor perf bug in gemm_ker_var2.
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.
commit b053337387dbdef9035be03538222670a21707ca
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 10 18:26:55 2013 -0500
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.
commit be4833bd91c5a58d0bfc52daaadf7ba543a77acf
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 10 14:20:06 2013 -0500
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.
commit 680188d46bb15b9a1a2867638104939dc77ca2a1
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 10 13:23:37 2013 -0500
Cleaned up old test drivers.
Details:
- Minor updates to old test drivers in preparation for our participation
in ACM TOMS's replicated results initiative.
commit 3690bdd4f95769c935c410414112102cc3e108b1
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 10 11:45:33 2013 -0500
More updates to level-1f kernels for core2-sse3.
Details:
- Changed types in function signatures to match new prototypes. Meant to
include this in previous commit.
commit 661d5120cd7071f9b0c5cefc95f99f1361370ade
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Thu Oct 10 11:27:27 2013 -0500
Fixed outdated fusing factor macros in 1f kernels.
Details:
- Updated level-1f kernels for x86_64 and bgq to use renamed fusing factor
macros. Meant to include this in 5e54f46c. Thanks to Fran for pointing
this out.
commit 73aa1e9f31d1b2a319c7e711ced6db3f9835c832
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Oct 1 17:01:18 2013 -0500
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.)
commit 5e54f46ccb76beab892d530b693e07c6bf6db7cf
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 30 12:58:18 2013 -0500
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.
commit 97aaf220a847363b4da35935eca17790c0ef71f6
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Sep 17 10:51:36 2013 -0500
Added new kernels, configurations.
Details:
- Added various micro-kernels for the following architectures:
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".
commit fe979c5a114c877506a5697cdab1fc8cf2bcd303
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Sep 13 14:31:53 2013 -0500
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.
commit da77e9614f54f92f703f01e3b9bd67a83280150c
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Fri Sep 13 12:00:37 2013 -0500
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.
commit 631f347b7a99cb02757c534fd3ec5f723a2fdb0e
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Sep 10 17:17:28 2013 -0500
Added ESSL and Accelerate targets to test drivers.
Details:
- Added ESSL and Accelerate (OS X) targets to standalone test drivers'
Makefile in "test" directory. Thanks to Jeff Hammond for suggesting
/ providing this patch.
commit 7ae4d7a41d13ef5f1ceee217c000a5cf77a11128
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Sep 10 16:35:12 2013 -0500
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.
commit 068437736b41d51a1f5ec47839f059bf58a20413
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 9 14:07:58 2013 -0500
Fixed set-but-not-used compiler (gcc) warnings.
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.
commit 6dc85f63dcd5282340c9e00d585e97d70a21edc3
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 9 13:48:52 2013 -0500
Small fix to Windows defs.mk makefile fragment.
Details:
- Commented out a !include statement that was attempting to include a
version file that does not yet exist. For now, the version string is
hard-coded into defs.mk.
commit d141f9eeb6d1de7044b7429adf52d11c6fca620c
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 9 13:09:16 2013 -0500
Added Windows build system.
Details:
- 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).
commit 9b320e7406fb69e8b61a0085abe2ed89a96bdb68
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Mon Sep 9 11:04:46 2013 -0500
Edited bli_?lamch.c to avoid Windows keyword.
Details:
- Renamed "small" variable to "smnum" to avoid collision with Windows type
by the same name. This change is needed in advance of the upcoming Windows
build system.
commit 9013ad6ff2e9ace35e0cf44c32795c2f3d5be628
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Sep 4 13:36:07 2013 -0500
Switched integer typedefs (again) to C types.
Details:
- Redefined gint_t and guint_t in terms of the standard C types long int
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.
commit 981a60cfa07abac2e93697dfe12b0f076ab00a38
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Sep 4 12:09:11 2013 -0500
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.
commit b776ddcd4338b34f172ef78da0ac1d771a771ab4
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Sep 3 21:58:07 2013 -0500
Applied temp fix to typecasting bug in testsuite.
Details:
- Applied a temporary fix to the typecasting bug in the testsuite driver.
The fix involves casting both numerator and denominator to unsigned long.
This fix is more voodoo than science, as I can't be sure why it even
works.
commit 9ee6e125373869c4213c017ce772c38ecefba103
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Tue Sep 3 21:53:27 2013 -0500
Changed dimension spec for gemm in testsuite.
Details:
- Encounted a bizarre typecasting bug whereby the test suite was not
computing the proper dimension from the problem size and dimension
specification when the latter was set to -3. Will investigate.
Thanks to Fran for finding this "bug".
commit e8be081e68c385ab44d0fea8dade21d40c200b79
Author: Field G. Van Zee <field@cs.utexas.edu>
Date: Wed Aug 28 15:52:34 2013 -0500
Generalized matlab and file output in testsuite.
Details:
- Added a new option in input.general that allows outputting in
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

Added single/real gemm micro-kernel for x86_64.
Details:
- Added a single-precision real gemm micro-kernel in
kernels/x86_64/3/bli_gemm_opt_d4x4.c.
- Adjusted the single-precision real register blocksizes in
config/clarksville/bli_kernel.h to be 8x4.
- Added a missing comment to bli_packm_blk_var2.c that was present in
bli_packm_blk_var3.c

Fixed bug in bli_acquire_mpart_t2b(), _l2r().
Details:
- 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.
- Uncommented beta == 0 optimizaition code in
kernels/x86_64/3/bli_gemm_opt_d4x4.c.

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.

Fixed cpp guard typos in frame/compat/check files.
Details:
- Fixed instances of BLIS_ENABLE_BLIS2BLAS that should have been
BLIS_ENABLE_BLAS2BLIS. Thanks to Tyler for catching this.
- Fixed various syntax errors in the code that had yet to be compiled
due to the aforementioned bug.
commit f4ec28e723d28d998f1038f82da6986e44320ef6
Author: Field G. Van Zee <field@cs.utexas.edu>
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.

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.
