Well, I'd change my CFLAGS, for sure, so that I'd get all the benefits of having that better processor. What's your profile: x86 or x86_64 (amd64)?
For your processor, according to http://gentoo-wiki.com/Safe_Cflags (that I always like to check): > Intel Core 2 Duo/Quad / Xeon 51xx/53xx > > vendor_id : GenuineIntel > cpu family : 6 > model : 15 > model name : Intel(R) Core(TM)2 CPU XXXX @ XXXGHz > > *32 bit profile (x86)* > > CHOST="i686-pc-linux-gnu" > CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer" > CXXFLAGS="${CFLAGS}" > > *64 bit profile (amd64)* > > CHOST="x86_64-pc-linux-gnu" > CFLAGS="-march=nocona -O2 -pipe" > CXXFLAGS="${CFLAGS}" > > *Note:* > > - GCC 4.3 has > -march=core2[1]<http://www.gnu.org/software/gcc/gcc-4.3/changes.html>, > but Gentoo has nothing above 4.2 in portage. > > So, I'd change my make.conf to one of those (again, depending of your profile). And after that, even though some things may need a revdep-rebuild and it may take a while, why not emerge -e world? Regards, Saffi On 1/25/08, John covici <[EMAIL PROTECTED]> wrote: > > Hi folks.
