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.
-msssse3 -> -mssse3

Yeah, it was a typo, thanks!

As I know, -mfpmath=sse may slow some code speed in some architechures, but I don't know if it also is on ATOM.

No idea! Hopefully, some of the more knowledgeable on this ML could provide some insights.
