Ian, Is the intention to fill the gap between where we are now and the NV program4 extensions, or to start out on a new MESA-specific path which would include later on a MESA_gpu_program4 extension? The question is relevant because of things like condition-codes which are in the NV GPU4 extension. - If this is an intermediate step on the way to NV GPU4, then we should probably prefer condition-codes over predicates. - If we expect to define a Mesa GPU4, then sticking with predicates is fine. I guess in either case the Mesa IR can opt to choose predicates over cond-codes, but a great benefit of an extension like this is that we can point at Mesa IR and say "the semantics of this language are documented in MESA_gpu_program3". IE. if you're not intending to provide a Mesa SM4 extension, it might be better to stick closer to the NV usage for SM3 also.
