Safe CFLAGS - Xeon

[Dockland]

My soon to arrive Lenovo p520 comes shipped with a Xeon-W 2133 (hexa core @3.6 GHz) and i'm not sure about the CFLAGS, the Gentoo Linux Handbook states up to Skylake (sort of) that works with broadwell flag, but anyhow, that was before CGG 6, that is avalible for the new 17.x profiles.

 

Anyone have a pro tip on this matter? I can always go with march=native, but like to optimize stuff.

I'll answer this my self, -march=native works, unless I'm going to user distcc, but there are ways to get that working anyway. I'm not planning to use distcc, so I'll stick with =native.
