================
Comment at: llvm/lib/CodeGen/RegAllocGreedy.cpp:2460
+    if (DestSrc) {
+      const MachineOperand *Dest = DestSrc->Destination;
+      const MachineOperand *Src = DestSrc->Source;
----------------
Change both Dest and Src to Ref as in the original code.
`const MachineOperand &Dest = *DestSrc->Destination;`
That will avoid the additional changes you made below.
