I've mostly forward ported the old gallium double code, and have written most of ARB_gpu_shader_fp64 on top, Though the question I did want to ask Tom is if he is just going to expose hw that has doubles, or does he plan on emulating doubles. For a lot of GLSL4.0 GPUs from AMD fglrx emulates doubles using massive magic shaders, I'm unsure if we should have a lowering pass above/below the TGSI line for these types of situations and what that would mean for this CAP.
