No. You should look for m_GEODE. > The bug indeed seems only to happen for -march=native (haven't tested anything > besides native yet), BTW. I.e. if you don't specify an architecture at all, > ffreep won't get issued. Can you send the output of "gcc -march=native -v"? It looks that the driver doesn't detect correctly the type of your CPU. BTW: -march=geode should work OK. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37179
