Hi,
Does anyone have any suggestions for CFLAGS settings in make.conf for
an Intel Xeon 5500 series processor?
Should I use -march=core2 or nocona or native?
I am starting a fresh install of Gentoo on a new machine.
Thanks in advance.
Denis

Is this a fresh unstable install? If so, your gcc will be recent and you
should use "march=native"
Let the software figure it out.

Unless you use distcc

It's a fresh install but have never used unstable version. Would gcc
stable version 4.3.2-r3 work with using 'march=native'?
Won't be using distcc.
