Details:
- Added new memory alignment constants:
BLIS_HEAP_STRIDE_ALIGN_SIZE (previously assumed to be same as SYSTEM_MEM)
BLIS_CONTIG_ADDR_ALIGN_SIZE (previously assumed to be same as PAGE_SIZE)
BLIS_STACK_BUF_ALIGN_SIZE (previously not enforced)
and renamed existing ones
BLIS_SYSTEM_MEM_ALIGN_SIZE -> BLIS_HEAP_ADDR_ALIGN_SIZE
BLIS_CONTIG_MEM_ALIGN_SIZE -> BLIS_CONTIG_STRIDE_ALIGN_SIZE
to better convey what the alignment factor is used for (and what it is
not used for).
- Removed BLIS_ENABLE_SYSTEM_MEM_ALIGN. Dynamic memory alignment is now
disabled by setting BLIS_HEAP_STRIDE_ALIGN_SIZE to 1.
- Inserted instances of __attribute__((aligned(BLIS_STACK_BUF_ALIGN_SIZE)))
into macro-kernels to specify stack alignment of temporary buffers.
- Modified test suite driver to output new constants.
- Removed bli_align_dim_to_sys() and bli_align_dim_to_cmem(). Instead, we now
use bli_align_dim_to_size(), which takes a third argument (the desired
alignment).
