The particular argument to march has to be recognized by gcc; I'm not sure what versions (if any) supported prescott as this argument. > > > > Any opinions are appreciated. > > -O3 is a baaaaaad idea. Guys, I've been running -O3 ever since I installed gentoo. It's not broken on PII (or any x86 arch). Theoretically, it can slow down programs because of cache issues; I haven't seen this effect in practice. -O3 is edgy though. It has been broken (and certain arches) before, and may be now or in the future. -- Boyd Stephen Smith Jr. [EMAIL PROTECTED] ICQ: 514984 YM/AIM: DaTwinkDaddy -- gentoo-user@gentoo.org mailing list
