When I set up my gentoo box for the Pentium Processor Extreme Edition (dual core prescott), I just used -march=prescott in make.conf Which -march flag would be the most relevant gcc optimization for Intel Core 2 Duo? And is there explicit support in the latest gentoo kernel for Core 2 Duo, or does it go under Pentium 4 family? Thanks -- gentoo-user@gentoo.org mailing list
