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.
