It seems that -O3 might be causing intermittent problems with the f2c'ed packed and banded code. -O3 is retained for kernel code. Fixes#341 and fixes#342.
Details:
- Removed explicit reference to The University of Texas at Austin in the
third clause of the license comment blocks of all relevant files and
replaced it with a more all-encompassing "copyright holder(s)".
- Removed duplicate words ("derived") from a few kernels' license
comment blocks.
- Homogenized license comment block in kernels/zen/3/bli_gemm_small.c
with format of all other comment blocks.
Details:
- Added a new sub-configuration 'cortexa53', which is a mirror image
of cortexa57 except that it will use slightly different compiler
flags. Thanks to Mathieu Poumeyrol for making this suggestion after
discovering that the compiler flags being used by cortexa57 were
not working properly in certain OS X environments (the fix to which
is currently pending in pull request #245).
