May be just include your tests from Bug 40838? (even without testing) >From http://gcc.gnu.org/bugzilla/attachment.cgi?id=18656 Your suggestions? I understand so there are same results with your gcc-4.4-pr40838-*.patch, but realigning whole code and exclude "misaligned" AMD CPUs. And warrantied to realign in any place. Your gcc-4.4-pr40838-3.patch lost realigning in unknown place - runtime segfaults in Seamonkey. *-4.patch I don't test becouse alredy use simple "-mstackrealign" solution - first there are dummy testing - surfing with Seamonkey until sometimes segfault, second - I got new desktop with Athlon (but was alredy satisfyed by "-mstackrealign" on old Celeron). Now I prefer to use safe "-mstackrealign" solution for Intel CPUs on 32bit servers and to be sure in safe SSE code. And see no visual defferences in perfomance whith global "-mstackrealign". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41156
