Subject: Possibility of adding -march=native to x86
Date: Thu, 25 Oct 2007 19:33:35 +0100	[thread overview]

Hi

I was wondering if it was possible to add -march=native support to the
processor options of the new x86 architecture if gcc 4.2 or greater is being
used.

I'm not suggesting this should be a default at all, merely an extra option
similar to selecting P4, Athlon or even -Os.

I've manually tried this flag at home with no ill effects.

Mike
