[PATCH] D85234: [AMDGPU] Scavenge a temp register for AGPR spill in fast RA

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.cpp:1361
+      MachineRegisterInfo &MRI = MF->getRegInfo();
+      Tmp = MRI.createVirtualRegister(&AMDGPU::VGPR_32RegClass);
+    }
----------------
I think this should be dealt with in eliminateFrameIndex rather than trying to speculatively add the def here
