Yeah, I just meant the more immediate situation that st_glsl_to_tgsi will fail because it will try to use FMA for double values. You could just as well add a thing to get_opcode() which selects DMAD as the double alternate to FMA. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
