Greets, I recently bought a new CPU for my mythtv-box, it's a Pentium
Dual E2160 ....

Currently I use

CFLAGS="-O2 -march=pentium4 -pipe -fomit-frame-pointer"

as I moved the system over from a Pentium 4 (which just crashed).

Things work fine so far, I checked google and
http://gentoo-wiki.com/Safe_Cflags for a hint, also browsed the
GCC-docs, but haven't yet found anything specific.

It's not really important, I don't face any problems, but as I just
think of it again I thought I just post a request, as that CPU isn't
mentioned in that Wiki-page.

Any recommended "-march" for that CPU? Maybe it helps with mythtv.

Thanks in advance, Stefan.
