- Subject: GCC 4.0.0 Performance Regressions?
Is anybody collecting information on performance regressions in 4.0.0 (vs.
3.4.3)? I've got some results on POVRAY and BYTEmark, and BYTEmark saw some
performance regression, particularly with profiled optimization
(-fprofile-{generate,use}):

I looked at the Bugzilla bug posting guidelines, but I don't know how to
boil this down to a tight testcase that fits those guidelines... and most of
what I saw in Bugzilla pertained to actual breakage anyway.
I'm willing to help out with this if I can get some pointers on what would
be useful to you--and if I can get the time away from my Real Work(TM) to
fiddle with this...
