I now know the thing that makes it break. cc -O2 -pipe -mcpu=pentiumpro -c /usr/src/lib/msun/src/e_pow.c works fine! cc -O0 -pipe -march=pentium4 -c /usr/src/lib/msun/src/e_pow.c ... works but... cc -O -pipe -march=pentium4 -c /usr/src/lib/msun/src/e_pow.c breaks it. Hey its only gcc :-), nothing to worry about. I think that 0 is nice number: so why don't optimize everithing to down it. -O seems to minimize numbers not calculation time. Does anyone know the flag to turn that off. till To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
