================
Comment at: llvm/lib/CodeGen/RegAllocGreedy.cpp:2374
- MachineOperand &Src = MI.getOperand(1);
- if (Dest.isReg() && Src.isReg() && Dest.getReg().isVirtual() &&
- Src.getReg().isVirtual())
----------------
Note for reviewers: We don't need the `isReg()` check as `COPY`s are only allowed between register operands.
