Elie has been working on soft-fp64 code in a branch for a while, and I've been slowly helping trying to get it in place so we can enable GL4.x on the evergreen GPUs.
However I've discovered on cayman we don't have int->double or uint->double support, and my conversion functions which did (int->f32->f64, and uint->f32->f64) weren't passing CTS tests or piglits. Instead of trying to do all this work in the r600 shader code, I've decided to start bringing in some of Elie's work now, and using it to fix the problem. This isn't soft-fp64, but it adds some of the required infrastructure that it will need, and might be an easier way to start introducing the big picture.
