Details:
- Textually replaced nearly all non-comment instances of bool_t with the
C99 bool type. A few remaining instances, such as those in the files
bli_herk_x_ker_var2.c, bli_trmm_xx_ker_var2.c, and
bli_trsm_xx_ker_var2.c, were promoted to dim_t since they were being
used not for boolean purposes but to index into an array.
- This commit constitutes the third phase of a transition toward using
C99's bool instead of bool_t, which was raised in issue #420. The first
phase, which cleaned up various typecasts in preparation for using
bool as the basis for bool_t (instead of gint_t), was implemented by
commit a69a4d7. The second phase, which redefined the bool_t typedef
in terms of bool (from gint_t), was implemented by commit 2c554c2.
Details:
- Fixed various typecasts in
frame/base/bli_cntx.h
frame/base/bli_mbool.h
frame/base/bli_rntm.h
frame/include/bli_misc_macro_defs.h
frame/include/bli_obj_macro_defs.h
frame/include/bli_param_macro_defs.h
that were missing or being done improperly/incompletely. For example,
many return values were being typecast as
(bool_t)x && y
rather than
(bool_t)(x && y)
Thankfully, none of these deficiencies had manifested as actual bugs
at the time of this commit.
- Changed the return type of bli_env_get_var() from dim_t to gint_t.
This reflects the fact that bli_env_get_var() needs to be able to
return a signed integer, and even though dim_t is currently defined
as a signed integer, it does not intuitively appear to necessarily be
signed by inspection (i.e., an integer named "dim_t" for matrix
"dimension"). Also, updated use of bli_env_get_var() within
bli_pack.c to reflect the changed return type.
- Redefined type of thrcomm_t.barrier_sense field from bool_t to gint_t
and added comments to the bli_thrcomm_*.h files that will explain a
planned replacement of bool_t with C99's bool type.
- Note: These changes are being made to facilitate the substitution of
'bool' for 'bool_t', which will eliminate the namespace conflict with
arm_sve.h as reported in issue #420. This commit implements the first
phase of that transition. Thanks to RuQing Xu for reporting this
issue.
- 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:
- 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:
- 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.
