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:
- 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:
- 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.
Details:
- Added function definitions for bli_pthread_cond_*() as well as related
types and constants to bli_pthread.c, and corresponding prototypes to
bli_pthread.h.
Details:
- Fully define bli_pthreads barrier-related types on OS X. Only typedef
those types in terms of pthreads types on non-Windows, non-Apple OSes
(i.e. Linux).
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.
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.
