Welcome to the rabbit trail. In order to fix Football Manager, I had to rework INTEL_DEBUG=shader_time in the FS backend. While doing that, I hit two assertion failures. After fixing that, I compared numbers. I noticed that VS again accounted for 0 cycles.
Matt - could you take a look at brw_vec4_dead_code_elimination.cpp? Since 5df88c2096281f (the rewrite to use live intervals), it's again completely eating the atomic buffer offset initialization, resulting in us using garbage data in the first register (of an mlen 2 message). (Sounds like the same bug I fixed in d0575d98fc595dcc17706dc73d1eb4.) With these patches, and the new vec4 DCE pass reverted, 10.3 vs my branch produce basically the same numbers on an openarena timedemo. Available in the 'football-v3' branch of my tree. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
