Actually the volatiles might be still useful. Or if you drop them at least add memory clobbers. I had sometimes bugs on x86-64 with the compiler moving such assembly statements with invisible side effects around too aggressively and causing weird problems. Agreed on the underscores, I hate them too :) Well, put volatiles in *unless* the only effect of an asm statement is producing the output values. -hpa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
