[PATCH] D122286: [AMDGPU] Add missing testcase for SGPR to AGPR copy

[Christudasan Devadasan via Phabricator via llvm-commits]

cdevadas added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/SIInstrInfo.cpp:628
+      break;
+    Tmp = Tmp2;
     RS.setRegUsed(Tmp);
----------------
Shouldn't this be Tmp = MIN (Tmp, Tmp2) if Tmp2 is a valid RegNo?
RS might return a higher number than the reserved.
