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.
- CREDITS file update.
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.
Details:
- Removed explicit reference to The University of Texas at Austin in the
third clause of the license comment blocks of all relevant files and
replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
with format of all other comment blocks.
Details:
- Removed four trailing spaces after "BLIS" that occurs in most files'
commented-out license headers.
- Added UT copyright lines to some files. (These files previously had
only AMD copyright lines but were contributed to by both UT and AMD.)
- In some files' copyright lines, expanded 'The University of Texas' to
'The University of Texas at Austin'.
- Fixed various typos/misspellings in some license headers.
Details:
- Renamed the various configurations' "bli_arch_<configname>.h" header files
(replacing "arch" with "family") to free up the 'bli_arch' namespace for a
different purpose (hardware detection).
- Renamed "bli_arch.h" and "bli_arch_pre_macro_defs.h" in frame/include to
"bli_arch_config.h" and "bli_arch_config_pre.h", respectively.
