------- Comment #14 from whaley at cs dot utsa dot edu 2006-06-14 02:40 ------- OK, I got access to some older machines, and it appears that Core is the only architecture that likes gcc 4's code. More precisely, I have confirmed that the following architectures run significantly slower using gcc4 than gcc 3: Pentium-D, P4e, Pentium III, PentiumPRO, Athlon-64 X2, Opteron.
Any help appreciated, Clint -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27827
