[Kai Luo via Phabricator via llvm-commits]

lkail added inline comments.


================
Comment at: llvm/lib/Target/PowerPC/PPCInstrInfo.cpp:2677
+  if (MRI.isSSA() && StartMI->findRegisterUseOperandIdx(RegNo) < 0 &&
+      StartMI->findRegisterDefOperandIdx(RegNo) < 0) {
+    assert(Register::isVirtualRegister(RegNo) && "Must be a virtual register");
----------------
Oops, should be `findRegisterUseOperandIdx(RegNo) < 0` -> `!readsRegister(RegNo)`
