Are these any options in the kernel and in the gcc to optimize for
Intel's Core 2 Duo chips?  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

A gentoo forum thread[1] states to use -march=nocona for Core 2 Duo, and -march=prescott for Core  Solo/Duo.
