I just noticed something weird on my P4 desktop using: gcc version 3.2.1 [FreeBSD] 20021009 (prerelease) If I build libm with -march=pentium4, then the mozilla theme "Oribit" looks corrupt. If I use -march=pentium3, the problem goes away. I've left xwindow dumps on freefall in ~gallatin/mozilla.bad.xwd ~gallatin/mozilla.good.xwd This is a terrible example in that its impossible to tell what happened, but it sure shows that something is wrong. Is there a floating point regression suite that you can point me at? That would be more useful for debugging.
