[PATCH] D140496: [TailDuplicator] Fix old bugs in TailDuplicator::duplicateInstruction

[Krzysztof Parzyszek via Phabricator via llvm-commits]

kparzysz added inline comments.


================
Comment at: llvm/lib/CodeGen/TailDuplicator.cpp:454
               NewRC = OrigRC;
             Register NewReg = MRI->createVirtualRegister(NewRC);
             BuildMI(*PredBB, NewMI, NewMI.getDebugLoc(),
----------------
Maybe we can just use `OrigRC` here, instead of trying to come up with a new class?  `OrigRC` is guaranteed to be valid, since that's what the original code used.
