I recently worked with a UCLA student to boil down a reported openssl performance regression with gcc-4.0 to a small standalone case (see http://gcc.gnu.org/PR19923). We have a bit more followup to do there, but it seems to have been a good use of an student's time.
So, I'm looking around for other reports of performance regressions in gcc-4.0. So far, the only other ones I've heard of are those reported in http://www.coyotegulch.com/reviews/gcc4/ I'm tempted to have a student try reproducing and boiling down the POV-Ray performance regession first. Has anyone else already done that? I'd hate to repeat work. Thanks, Dan
