* AMDGPU: Use SGPR_128 instead of SReg_128 for vregsMatt Arsenault2019-10-101-4/+4
| | | | | | | | | 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
* AMDGPU/GlobalISel: Increase max legal size to 1024Matt Arsenault2019-10-011-0/+26
| | | | | | | | There are 1024 bit register classes defined for AGPRs. Additionally OpenCL defines vectors up to 16 x i64, and this helps those tests legalize. llvm-svn: 373350
