Motivated by some troubles in register allocation on Valve's shaders, I found a cheap (runtime and development time) way to cut some dead code. This looked like failure due to losing 16-wide programs, until I updated more apps in shader-db to use shader_tests (which provide more accurate simulation, since your FS attributes are no longer demoted to undefined temporary values).
shader-db results: total instructions in shared programs: 1735753 -> 1731698 (-0.23%) instructions in affected programs: 492620 -> 488565 (-0.82%) There are also a few cleanup patches attached that have been kicking around several optimization branches I have. This series is on the local-dce branch of my tree. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
