================
Comment at: llvm/test/CodeGen/AMDGPU/GlobalISel/regbankselect-amdgcn.s.buffer.load.ll:34
+  ; GREEDY:   $sgpr0 = COPY [[INT]](s32)
+  ; GREEDY:   SI_RETURN_TO_EPILOG implicit $sgpr0
   %val = call i32 @llvm.amdgcn.s.buffer.load.i32(<4 x i32> %rsrc, i32 %soffset, i32 0)
----------------
FYI, this change is just that update_mir now doesn't want to reuse prefixes for RUN lines :(.
