[gentoo-user] What cpu type in make.conf for E4600

[gentoo-user] What cpu type in make.conf for E4600

[waltdnes]

  A computer of mine died, and I'm now setting up the replacement.  What
do I set -march= to in /etc/make.conf?  Below is cpuinfo data for one of
the cores...

livecd gentoo # cat /proc/cpuinfo

core2 if you use GCC 4.3, nocona for earlier, or set it to native if you
don't use distcc.

http://gentoo-wiki.com/Safe_Cflags suggests using:

"-march=prescott" for 32-bit
"-march=nocona" for 64-bit.

  any idea which gcc version is installed by stage3-i686-2008.0_beta2
(along with portage-2008.0_beta2 snapshot)?  that makes a difference.
I'll be staying with 32-bit for now,  That's why I ordered "only" 3 gigs
of ram on this machine.

  Thanks for the link; it looks like prescott in my case.

No, but gcc -v will tell you. I'd guess it was 4.1.2 though, that's the
most recent stable version.

In which case, the distinction is moot, use prescott.

This is the day for firm decisions! Or is it?
