[PATCH] D138515: [CodeGen][RegAllocFast] Map PhysReg to its current VirtReg

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/include/llvm/CodeGen/MachineRegisterInfo.h:781
+  void setPhysToCurrentVirtReg(Register Reg) { PhysToCurrentVirtReg = Reg; }
+  Register getPhysToCurrentVirtReg() const { return PhysToCurrentVirtReg; }
+
----------------
Why pollute MRI with this, this is state local to RegAllocFast
