[PATCH] D55987: [CodeGen] Skip over dbg-instr in twoaddr pass

[Adrian Prantl via Phabricator via llvm-commits]

aprantl added inline comments.


================
Comment at: lib/CodeGen/TwoAddressInstructionPass.cpp:932
   MachineBasicBlock::iterator End = AfterMI;
-  while (End->isCopy() &&
-         regOverlapsSet(Defs, End->getOperand(1).getReg(), TRI)) {
-    Defs.push_back(End->getOperand(0).getReg());
+  while (End->isDebugInstr() ||
+         (End->isCopy() &&
----------------
For IR we have an iterator that skips over debug intrinsics automatically. Does the same thing exist for MIR, too?
