Replying to an old thread, but FYI this problem which has been bugging me since months has gone away since the lastest clang branches/release_30 import, and it has been MFC'ed to stable/9. I can now buildworld with -march=corei7 instead of -march=core2 :) (the same should apply for -march=native) Cheers -- Olivier Smedts _ ASCII ribbon campaign ( ) e-mail: olivier@gid0.org - against HTML email & vCards X www: http://www.gid0.org - against proprietary attachments / \ "Il y a seulement 10 sortes de gens dans le monde : ceux qui comprennent le binaire, et ceux qui ne le comprennent pas."
