--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-09-24 12:35:02 UTC --- (In reply to comment #0) > But, if that is true, gcc man page should be fixed to drop "k8-sse3" from > -mtune options No, because it's a valid option. Since -march=k8 and -march-k8-sse3 do not do that same thing, it belongs in the manual as a supported arch. What the downstream reply says is that there's no difference between -mtune=k8 and -mtune=k8-sse3, so it doesn't matter that gcc uses -mtune=k8, you get the same result. If -mtune=k8 and -mtune=k8-sse3 do the same thing, why do you care which is used?
