BTW, Pierre Moreau is working on a SPIR-V -> nv50 ir adapter, which will hopefully mean that once a SPIR-V llvm backend exists (such a thing *is* in the plans by... someone, right?) that would be able to be used. He hasn't made a lot of progress though. Among other things, SPIR-V is SSA, and nv50 ir input has to be non-ssa (because, among other things, the various lowering passes generate non-ssa code, futz with control flow, etc). -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
