------- Comment #8 from Joey dot ye at intel dot com 2008-11-21 12:00 ------- In short, set A={-favx, -ffma}, set B={-f3dnow, -f3dnowa, -fsse4a, -fsse5}. Any option combination from both sets should be prohibited.
Please add more options into these set in case I missed any. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38201
