From Gentoo Wiki
Being aware of the risks involved, take a look at some sane, safe optimizations. These will hold in good stead and will be endearing to developers the next time a problem is reported on Bugzilla. (Developers will usually request the user to recompile a package with minimal CFLAGS to see if the problem persists. Remember: aggressive flags can ruin code!)
