            Bug ID: 89819
           Summary: WebGL Conformance swrast failure in
                    conformance/uniforms/uniform-default-values.html
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Mesa core
          Assignee: mesa-dev at lists.freedesktop.org
          Reporter: lukebenes at hotmail.com
        QA Contact: mesa-dev at lists.freedesktop.org

The swrast renderer requires DRAW_USE_LLVM=false to pass the OGLES 2.0 Uniform
Default Values test.

Steps to reproduce:
1. set LIBGL_ALWAYS_SOFTWARE=1
2. visit
https://www.khronos.org/registry/webgl/sdk/tests/conformance/uniforms/uniform-default-values.html?webglVersion=1
3. set DRAW_USE_LLVM=false 
4.
https://www.khronos.org/registry/webgl/sdk/tests/conformance/uniforms/uniform-default-values.html?webglVersion=1


llvmpipe results:
testing: samplerCube
fragment shaderFAIL Error in program linking:null
FAIL uniform is not zero
default value should be zero
FAIL at (0, 0) expected: 0,255,0,255 was 0,0,0,0
test test by setting value
FAIL at (0, 0) expected: 255,0,0,255 was 0,0,0,0
re-linking should reset to defaults
FAIL at (0, 0) expected: 0,255,0,255 was 0,0,0,0
FAIL getError expected: NO_ERROR. Was CONTEXT_LOST_WEBGL : should be no GL
errors
