While doing some other work, I noticed that prog_to_nir supported SLE, SGT, SNE, and SEQ. It's impossible for those opcodes to occur in the prog_to_nir path because that could only have come from the NV_vertex_program2 (or other NV assembly program) extension. We removed those quite some time ago.
I was just going to remove that code, but I realized that nothing using ir_to_mesa wants to see those opcodes. i915 has to emit multiple instructions to do them, and prog_execute... well, I don't think anyone cares about that path seeing a couple extra instructions. After changing ir_to_mesa, there was quite a bit more code available for deletion. I tested this on our CI on G33 (i915-ish), and there were no regressions on GLES2 CTS or piglit. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
