Details: - NOTE: This is a merge commit of 'master' of git://github.com/amd/blis into 'amd-master' of flame/blis. - Fixed a bug in the downstream value of BLIS_NUM_ARCHS, which was inadvertantly not incremented when the Zen2 subconfiguration was added. - In bli_gemm_front(), added a missing conditional constraint around the call to bli_gemm_small() that ensures that the computation precision of C matches the storage precision of C. - In bli_syrk_front(), reorganized and relocated the notrans/trans logic that existed around the call to bli_syrk_small() into bli_syrk_small() to minimize the calling code footprint and also to bring that code into stylistic harmony with similar code in bli_gemm_front() and bli_trsm_front(). Also, replaced direct accessing of obj_t fields with proper accessor static functions (e.g. 'a->dim[0]' becomes 'bli_obj_length( a )'). - Added #ifdef BLIS_ENABLE_SMALL_MATRIX guard around prototypes for bli_gemm_small(), bli_syrk_small(), and bli_trsm_small(). This is strictly speaking unnecessary, but it serves as a useful visual cue to those who may be reading the files. - Removed cpp macro-protected small matrix debugging code from bli_trsm_front.c. - Added a GCC_OT_9_1_0 variable to build/config.mk.in to facilitate gcc version check for availability of -march=znver2, and added appropriate support to configure script. - Cleanups to compiler flags common to recent AMD microarchitectures in config/zen/amd_config.mk, including: removal of -march=znver1 et al. from CKVECFLAGS (since the -march flag is added within make_defs.mk); setting CRVECFLAGS similarly to CKVECFLAGS. - Cleanups to config/zen/bli_cntx_init_zen.c. - Cleanups, added comments to config/zen/make_defs.mk. - Cleanups to config/zen2/make_defs.mk, including making use of newly- added GCC_OT_9_1_0 and existing GCC_OT_6_1_0 to choose the correct set of compiler flags based on the version of gcc being used. - Reverted downstream changes to test/test_gemm.c. - Various whitespace/comment changes.
