I tested it with e_pow.c. funnily though using the pentiumpro proccessor cost table "fixes" the libm problem :-). the point still is though, that enabling other things (or like me changing the cost table) doesn' fix anything, because eg if someone changes some stuff not directly related to sse2 code selection again may find another rule for sse2 that is buggy again. I think no one should simply use the sse2 stuff at the moment, because you will notice problems too late. My mp3s sounded horrible and gv didn't display pdf files correctly. if there hadn't been libvorbis though that had a division by zero,however, i probably never would have located the bug. till To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
