[PATCH] D82194: [AMDGPU] Enable compare operations to be selected by divergence

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.cpp:6169-6170
     // Check if SCC is used first.
-    if (MI.findRegisterUseOperandIdx(AMDGPU::SCC, false, &RI) != -1) {
+    int SCCIdx = MI.findRegisterUseOperandIdx(AMDGPU::SCC, false, &RI);
+    if (SCCIdx != -1) {
       if (MI.isCopy()) {
----------------
MI.readsRegister(SCC)? I also think this would break if we ever bothered to use the feature of directly using scc in instruction operands
