            Bug ID: 111511
           Summary: integer cube sampling fails to build shader
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: not set
          Priority: not set
         Component: Drivers/Gallium/llvmpipe
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: airlied at freedesktop.org
        QA Contact: mesa-dev at lists.freedesktop.org

dEQP-GLES31.functional.texture.gather.basic.cube.rgba8ui.size_pot.clamp_to_edge_repeat

This fails to build due to 
lp_bld_bitarit.c:130:lp_build_andnot: Assertion `lp_check_value(type, a)'
failed.


I'm not sure how the averaging corner rules are supposed to work for integer
textures (do you have to do integer divide by 3?) but this code has some
coord_bld/texel_bld code if I had to guess.

lp_build_sample_image_linear
in the accurate_cube_corners case.
