[Nottingham] Athlon64 gcc compile flags on Gentoo

[Martin]

Folks,

I'm about to try out Gentoo on a Athlon64 box (yes, that ASUS one now
with updated BIOS)...

Any recommendations for a good combination of compiler flags beyond the
usual "-O3" (or "-Os" even)?

What have others found to work well?

Or does it all make negligible difference?

Cheers,
Martin
