            Bug ID: 107734
           Summary: [GLSL] glsl-fface-invariant, glsl-fcoord-invariant and
                    glsl-pcoord-invariant should fail
           Product: Mesa
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: glsl-compiler

GLSL ES 1.0 linker tests glsl-fface-invariant, glsl-fcoord-invariant and
glsl-pcoord-invariant have to fail as specified in spec: 

4.6.4 Invariance and Linkage
The invariance of varyings that are declared in both the vertex and fragment
shaders must match.For the built-in special variables, gl_FragCoord can only be
declared invariant if and only if gl_Position is declared invariant. Similarly
gl_PointCoord can only be declared invariant if and only if gl_PointSize is
declared invariant. It is an error to declare gl_FrontFacing as invariant. The
invariance of gl_FrontFacing is the same as the invariance of gl_Position.
