           Summary: [radeonsi]glsl: Override the # of varying slots for
                    ClipDistance and TessLevel*. broke chromium browser
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW

          Priority: medium

Hi, after upgrade mesa-git chromium starts looking like garbage.
I've tested this on polaris and i965(haswell) and only radeon is infected
kernel - 4.9 or 4.10-drm-next-wip
mesa - from git
llvm - r291295
ddx - amdgpu-git

bisecting:

    glsl: Override the # of varying slots for ClipDistance and TessLevel*.

    Right now, this shouldn't have any effect, as all drivers use
    LowerClipDist and LowerTessFactors to turn the float[] arrays into
    vectors.

    However, it should help make it possible for drivers to avoid that
    lowering.
    me is the only issue for now
