This requires that we communicate to X86InstrInfo::optimizeCompareInstr that the second operand is neither a register nor an immediate. The way we do that is by setting CmpMask to zero. Note that there were already instructions where the second operand was not a register nor an immediate, namely X86::SUB*rm, so also set CmpMask to zero for those instructions. This seems like a latent bug, but I was unable to trigger it. Differential Revision: https://reviews.llvm.org/D28621 llvm-svn: 294634
