Details:
- Made substantial changes throughout the framework to decouple the leading
dimension (row or column stride) used within each packed micro-panel from
the corresponding register blocksize. It appears advantageous on some
systems to use, for example, packed micro-panels of A where the column
stride is greater than MR (whereas previously it was always equal to MR).
- Changes include:
- Added BLIS_EXTEND_[MNK]R_? macros, which specify how much extra padding
to use when packing micro-panels of A and B.
- Adjusted all packing routines and macro-kernels to use PACKMR and PACKNR
where appropriate, instead of MR and NR.
- Added pd field (panel dimension) to obj_t.
- New interface to bli_packm_cntl_obj_create().
- Renamed bli_obj_packed_length()/_width() macros to
bli_obj_padded_length()/_width().
- Removed local #defines for cache/register blocksizes in level-3 *_cntl.c.
- Print out new cache and register blocksize extensions in test suite.
- Also added new BLIS_EXTEND_[MNK]C_? macros for future use in using a larger
blocksize for edge cases, which can improve performance at the margins.
