VIA processors such as the C3 are PPro compatible *but* the GNU C compiler definition of i686 is (was ?) broken and incorrectly used cmov without checking if it was available. If gcc has been fixed or those options avoid cmov then it ought to cover any vaguely recent processor fine (and -mtune=atom seems to produce better code for older processors than i586) Alan -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
