            Bug ID: 102680
           Summary: [OpenGL CTS]
                    KHR-GL45.shader_ballot_tests.ShaderBallotBitmasks
                    assert fails
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/i965

KHR-GL45.shader_ballot_tests.ShaderBallotBitmasks hits an assertion failure in
the EU validator:

cts-runner: compiler/brw_reg_type.c:125: brw_hw_type_to_reg_type: Assertion
`!"not reached"' failed.

It's trying to find an immediate of HW type 15.  This is compiling a SIMD8 VS.

I know Jason has a bunch of patches out related to ballot, perhaps one of them
fixes it?
