gcc optimisation flags for Intel Atom

[Michael Zintakis <michael.zintakis@xxxxxxxxxxxxxx>]

I am reading some very different (and sometimes conflicting) opinions 
what these optimisation flags should be. So, what are the best flags to 
use to compile source code for running on Atom?

Personally, I think using "-O2 -march=atom -msssse3 -mfpmath=sse 
-fomit-frame-pointer -pipe" is decent enough. Any other opinions? I am 
using gcc 4.4.5.
