It would be a lot more work and way too uncertain, I reckon it's taken Timothy 6 months to get radeonsi even close with nir, I don't have 6 months to spend on getting r600 close, it's backend situation is a lot worse than radeonsi. > > Elie sent patches for lowering fp64 operations in NIR, and it's what > I'm going to start from when I do the analogous project for some > future Intel hardware.

Yes it sucks, but maybe the nir code will get a lot more effort put in and I can improve the GLSL code, I'm mostly hoping the GLSL code is fire and forget since I doubt anyone in the real world will ever use it.
