Sure, but it seemed to me that all the optimizations proposed were hardware-independent and valid for any driver (other than having to know about generic capabilities like having control flow or not). > even better job for superscalar r600. So yes, we need both LLVM to do global > optimizations and RC to efficiently map code to hw. LLVM also uses SSA form (actually, it is totally built around it), assuming that's what you meant. There are doubts about whether the LLVM backend framework works well for GPUs or not (apparently because some GPUs are VLIW and only IA-64 is VLIW too, so LLVM support for it is either nonexisting or not necessary a major focus), but using LLVM->TGSI makes this irrelevant, since the existing TGSI-accepting backend will still run. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
