Re: AMD64 optimization on FreeBSD 5.4 i386
Ok, I have found the solution CFLAGS += -march=k8 and use pkgtools.conf for certain application that doesn't support it. gcc32 gcc33 fr-openoffice ... doesn't the nvidia driver works on amd64 version of freebsd ? ok see ya Le Mon, Apr 04, 2005 at 06:54:00AM -0500, Conrad J.

AMD64 optimization on FreeBSD 5.4 i386
Hi, I have a AMD64 and use FreeBSD 5.4 i386. I have set CPUTYPE=k8 to optimize a little for my computer. I have seen they set march=athlon-mp when it compile something.

Does the -O2 flag give more errors or is it better than using the -O? To quote the Handbook: ``The optimization -O2 is much slower, and the optimization difference between -O and -O2 is normally negligible.'' The only reason one would want to use -O2 would be perfectionism, I think :) Best wishes, Andrew P. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
