Is there any chance for a --march / --mcpu pair for intel core(duo)? I'm currently running gentoo linux on a first generation mac book pro equipped with a intel coreduo processor. Gentoo installation guide states that --march=prescot is the best choice for my cpu. But there are also some guides stating that --march=native would result in better usage of the coreduo's features.
Left with this I was hoping for a intel core cpu-target in gcc 4.3 (which only seems to support core2..) Is it even possible to fine tune for core(duo)? Thank's in advance René (Sorry if this question was asked before - I searched the mailing-lists and bugzilla without results.)
