I have an Ezra or an Ezra-T core (the only difference is Tualatin <sp> compatibility), and it produces an Unknown. If you have a 'Samuel2' core, then you have a Samuel2 core. It's neither Ezra nor Ezra-T -- those two are the successors to Samuel2. > However, if you have a C3 without SSE, it's basically a K6 with MMX > and 3dNow.

That's been working for me as well -- I'd be interested to see which is more optimized. Does your chip understand CMOV? GCC presumes that a 686-class processor has CMOV, and while the C3 /is/ a 686-class processor, it doesn't do CMOV. But I heard a rumor that the Samuel2 core /does/ do CMOV... _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
