+ if (Opcode == AMDGPU::G_FNEG) {
+ Src = MI->getOperand(1).getReg();
----------------
Since you are stripping bitcasts, don't you need the same kind of type check as in D116441, to make sure it is a 16-bit fneg?
================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUInstructionSelector.cpp:3587
+ Mods ^= SISrcMods::NEG;
+ } else if (Opcode == AMDGPU::G_FABS) {
+ Src = MI->getOperand(1).getReg();
----------------
Likewise.
