================
Comment at: lib/CodeGen/SelectionDAG/SelectionDAG.cpp:3969
+      if (OpOp.getValueType() == VT) {
+        transferDbgValues(Operand, OpOp, 0, 0, false);
         return OpOp;
----------------
Why is InvalidateDbg false? Does the debug value attached to Operand need to remain valid after it's cloned and attached to OpOp?
