glsl: Don't require matching centroid qualifiers
Note: This patch appears to violate older OpenGL and OpenGLES specs. The OpenGLES GLSL 3.1 and OpenGL GLSL 4.3 specifications both remove the requirement for the output and input centroid qualifiers to match. The deqp dEQP-GLES3.functional.shaders.linkage.varying.rules.differing_interpolation_2 test wants the newer OpenGLES 3.1 specification behavior, even for OpenGLES 3.0. This patch simply removes the checking in all cases. The OpenGLES 3.0 conformance test suite doesn't appear to require the older ("must match") spec behavior. For reference, here are the relavent spec citations: The OpenGL 4.2 spec says: "the last active shader stage output variables and fragment shader input variables of the same name must match in type and qualification (other than out matching to in)" The OpenGL 4.3 spec says: "interpolation qualification (e.g., flat) and auxiliary qualification (e.g. centroid) may differ." The OpenGLES GLSL 3.00.4 specification says: "The output of the vertex shader and the input of the fragment shader form an interface. For this interface, vertex shader output variables and fragment shader input variables of the same name must match in type and qualification (other than precision and out matching to in)." The OpenGLES GLSL 3.10 Specification says: "interpolation qualification (e.g., flat) and auxiliary qualification (e.g. centroid) may differ" Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=92743 Bugzilla: https://cvs.khronos.org/bugzilla/show_bug.cgi?id=7819 Signed-off-by: Jordan Justen <[email protected]> Cc: Ian Romanick <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>
