mesa/st: glsl_to_tgsi: tie in new temporary register merge approach\n\nThis patch replaces the old register lifetime estiamtion and\nrename mapping evaluation with the new one.\n\nPerformance to compare between the current and the new implementation\nwere measured by running the shader-db in one thread.\n\n-----------------------------------------------------------\n old new(std::sort)\n\n---------------- time ./run -j1 shaders --------------------\n\n real 5.80s 5.75s\n user 5.75s 5.70s\n sys 0.05s 0.05s\n\n---- valgrind --tool=callgrind --dump-instr=yes------------\n\n merge 0.08% 0.18%\n estimate lifetime 0.02% 0.11%\n evaluate mapping (incl=0.3%) 0.04%\n apply mapping 0.03% 0.02%\n\n--- perf (approximate because of statistic sampling) ----\n\nmerge (total) 0.09% 0.16%\nestimate lifetime 0.03% 0.10%\nevaluate mapping (incl=0.02%) 0.04%\napply mapping 0.04% 0.04%\n\nReviewed-by: Nicolai Hähnle <[email protected]>
