subregister operands like this: %reg1040:sub_32bit<def> = MOV32rm <fi#-2>, 1, %reg0, 0, %reg0, %reg1040<imp-def>; mem:LD4[FixedStack-2](align=8) Make them return false when subreg operands are present. VirtRegRewriter is making bad assumptions otherwise. This fixes PR7713. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@109489 91177308-0d34-0410-b5e6-96231b3b80d8
