------- Additional Comments From bonzini at gcc dot gnu dot org 2005-09-30 10:15 ------- To calculate the numbers I gave you, I took the sum of the percentages in the profiling snippets, and the cumulative time for the last line of the profiling snippets. Then pct * 100 / time obviously gives you the total running time.
The original bug report gives the -fno-fast-math timing top functions account for 28.3%, seconds = 4.34 --> total time = 15.33 Comment #4 gives the timing with -ffast-math but without recip: top functions account for 44.94%, seconds = 6.93 --> total time = 14.21 Comment #6 gives the times with -ffast-math and the new recip: top functions account for 37.96%, seconds = 5.97 --> total time = 13.88 So it seems that the patch introduces a speedup. If not, can you provide profiling output for the two povray's in comment %9 (either on abyss.pov, or on the standard POVray benchmark)?
