Matt Arsenault	12994a70cf	AMDGPU: Use SGPR_128 instead of SReg_128 for vregs SGPR_128 only includes the real allocatable SGPRs, and SReg_128 adds the additional non-allocatable TTMP registers. There's no point in allocating SReg_128 vregs. This shrinks the size of the classes regalloc needs to consider, which is usually good. llvm-svn: 374284	2019-10-10 07:11:33 +00:00

AMDGPU: Use SGPR_128 instead of SReg_128 for vregs

SGPR_128 only includes the real allocatable SGPRs, and SReg_128 adds
the additional non-allocatable TTMP registers. There's no point in
allocating SReg_128 vregs. This shrinks the size of the classes
regalloc needs to consider, which is usually good.
