[Mesa-dev] [PATCH 0/7] Beginnings of ARB_shading_language_420pack

[Matt Turner]

I'm on vacation for the next week, so in case anyone else wants to
finish off ARB_shading_language_420pack, here are the tests and
patches I've done so far.

They cover
 - Swizzles on scalars
 - .length() method of matrices and vectors
 - gl_{Max,Min}ProgramTexelOffset built-in constants (needs a piglit test)
 - Implicit conversion of return values
 - Non-constant expression initializers of const variables
 - and a GLSL spec clarification tacked on at the end

Thanks,
Matt
