-march implies -mcpu. For x86, -mcpu alone produces code that'll run on a 386 but is (in theory) optimized for a specific processor. -march goes one step further and uses processor-specific features, such as newer instructions (e.g., CMOV, which exists in Pentium Pro and newer CPUs). _______________________________________________ Xmame mailing list [EMAIL PROTECTED] http://toybox.twisted.org.uk/mailman/listinfo/xmame
