------- Additional Comments From pinskia at gcc dot gnu dot org 2004-11-18 14:31 ------- I think this fixed except I have not checked with checking turned off. With checking still on I get the following passes as hot: dominator optimization: 31.03 (42%) usr 0.02 ( 1%) sys 31.26 (40%) wall tree SSA verifier : 5.64 ( 8%) usr 0.00 ( 0%) sys 5.68 ( 7%) wall rename registers : 7.37 (10%) usr 0.02 ( 1%) sys 7.46 (10%) wall
But cfg cleanup went down a huge amount: tree CFG cleanup : 1.23 ( 2%) usr 0.00 ( 0%) sys 1.25 ( 2%) wall Before (20041113) on a slightly faster machine and different OS: tree CFG cleanup : 33.36 (43%) usr 0.01 ( 1%) sys 33.41 (42%) wall tree split crit edges : 16.83 (22%) usr 0.01 ( 1%) sys 16.87 (21%) wall dominator optimization: 7.94 (10%) usr 0.03 ( 2%) sys 7.97 (10%) wall tree SSA verifier : 2.57 ( 3%) usr 0.01 ( 1%) sys 2.53 ( 3%) wall rename registers : 5.57 ( 7%) usr 0.03 ( 2%) sys 5.61 ( 7%) wall Hmm, either DOM was just slowed down (because of checking) or something is really different between these two OS's. But as you can see that tree CFG cleanup and tree split crit edges have sped up a lot. I will try to get a new compiler built without checking turned on later today to get final numbers. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=15524
