[PATCH] D120202: [AMDGPU] Extend pre-emit peephole to redundantly masked VCC

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIPreEmitPeephole.cpp:148
+    if (A->getOpcode() == And && SReg == CondReg && !ModifiesExec &&
+        (M->isCompare() || TII->isVOPC(*M)) && TII->isVALU(*M)) {
+      A->eraseFromParent();
----------------
I think isCompare is always redundant with isVOPC
