I did see a precision patch by Vitaliy fixing this problem, which was not applied, presumably since there is a better way to fix this. > Renaming the local > constants from LC to LVC for vertex and LPC for pixel shaders, and then > loading the uniforms after program linking should fix the issue for GLSL.

I assume this is done for performance reasons, is this correct ? I see your patch is special-case disabled in the case of relative addressing. Do we really want to support multiple constant loading code paths for performance savings ?
