[PATCH] D133610: [RegisterCoalescer] Use LiveRangeEdit to handle rematerialization

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/CodeGen/LiveRangeEdit.cpp:197
+  if (ReplaceIndexMI)
+    return LIS.ReplaceMachineInstrInMaps(*ReplaceIndexMI, *MI);
   return LIS.getSlotIndexes()->insertMachineInstrInMaps(*MI, Late).getRegSlot();
----------------
Shouldn't this return getRegSlot like the fallthrough case?
