Sort of off-topic, but it would be really nice if you could do this. A lot of the code Jason wrote for NIR is about dealing with indirect array accesses, which currently get lowered to if-ladders in GLSL which makes all of it dead code. It would be nice to be able to bugfix + test it. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
