            Bug ID: 31230
           Summary: test/CodeGen/AMDGPU/attr-amdgpu-num-sgpr.ll
                    max_12_sgprs_12_input_sgprs needs to be updated after
                    D26687
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: AMDGPU
          Assignee: unassignedbugs at nondot.org
          Reporter: matze at braunis.de
                CC: llvm-bugs at lists.llvm.org
    Classification: Unclassified

The testcase max_12_sgprs_12_input_sgprs in
test/CodeGen/AMDGPU/attr-amdgpu-num-sgpr.ll needs an update after D26687.

It relies on coalescing a "%vreg1 = COPY SGPR4_SGPR5" copy with SGPR4 being
reserved while SGPR5 is not, which the patch forbids.

I will comment the test out for now.
