POWER ISA 3.1 added new Matrix-Multiply Assist (MMA) instructions.
The following patch set adds support for generating these instructions
through built-in functions which are enabled with the -mmma option.
The patch1 and patch1+patch2+patch3 have been bootstrapped and regtested on
powerpc64le-linux with no regressions. In addition, patch1+patch2+patch3
has been bootstrapped and regtested on powerpc64-linux (BE), also without
regressions. I'll note that I split the testsuite changes into their own
patch for review purposes, but I plan on committing patch2 and patch3 together.
Changes since v1:
Patch 1/3:
- Modified verbiage in mma.md per Will's suggestion.
- Modified rs6000_split_multireg_move to correctly handle BE PXImode
and POImode moves.
Patch 2/3:
- Updated ChangeLog entry per Segher's suggestion.
- Updated doc/extend.texi with correct built-in names for
__builtin_vsx_xvcvspbf16 and __builtin_vsx_xvcvbf16sp.
Patch 3/3:
- No changes.
