[Mesa-dev] [PATCH 3/3] r600g: Handle texture fetch instructions with relative addressing

[Fabian Bieler]

Note: As far as I know, this is currently dead code:
For glsl shaders the glsl IR to Mesa gl_program converter adds a  mov 
instruction for all texture fetch coordinates that isn't removed by Mesa's IR 
code optimizations in case of relative addressing.
ARB_fragment_program doesn't support relative addressing.
ARB_vertex_program doesn't support texture fetches.
