Author: Dave Airlie <airlied@redhat.com> In order to implement indirect sampler loads, we don't want to match on a VGPR load but an SGPR one for constants, as we cannot feed VGPRs to the sampler only SGPRs. this should be applicable for llvm 3.7 as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@243294 91177308-0d34-0410-b5e6-96231b3b80d8
