Luca, I see our point of agreement being that we want to help drivers avoid re-translating shaders at binding time. Our disagreement basically boils down to a difference between improving things on one type of hardware (with fixed-function interpolators) versus doing a better job everywhere, in particular also helping hardware that does interpolation in the shader (i965, llvmpipe, r800?). Right now, I feel like you're basically dug in and arguing the same point again and again. That makes it really hard to work on finding a path forward that addresses both of our concerns. Personally I'm going to take a break from this thread, spend a couple of days looking at i965, etc, to see what can be done to improve things there, and maybe come back with an alternate proposal.
