My conclusion is: clang incorrectly produces code within one of core libraries (I haven't tested which one yet, but I suspect libgcc_s.so) when optimizing for athlon-4 or athlon-xp.I am not versed in the AMD marketing monikers. I guess that athlon-{4,xp} turns on SSE and might be SSE2, while previous selections turn it off. Can you confirm/deny this ?
As http://en.wikipedia.org/wiki/Athlon states athlon-xp was first to include SSE support. I don't know whether athlon-xp actually differs from athlon-4. None of them include SSE2 support.
BTW, did you tested on i386 or amd64 ?
i386 -- Sphinx of black quartz, judge my vow. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
