Details: - Updated/clarified the ARM preprocessor macro branch of bli_cpuid.c. Going forward, cortexa57 (64-bit), cortexa15, and cortexa9 (32-bit) sub-configurations are supported. However, the functions that detect features specific to a15 and a9 are identical, and since a15 is tested first, it will always be chosen for arm32 hardware (even if both sub-configurations were enabled at configure-time and the library is linked and run on an a9). Thus, more work needs to be done to distinguish these two. - Added cpp guard around x86_64 portions of bli_cpuid.c. Now, either the x86_64 or ARM code will be compiled (or neither, if neither environment is detected). - In bli_arch_query_id(), call bli_cpuid_query_id() when the BLIS_FAMILY_ARM64 or BLIS_FAMILY_ARM32 macros are defined. - Added arm64 and arm32 configuration families to config_registry. - Added a note to the arch_t typedef enum in bli_type_defs.h reminding the developer to update the string array in bli_arch.c whenever new enum values are added or existing values are reordered.
