Sure, but it may be worth considering the effects on other platforms, present and future, possibly including future Intel. If it's not a big performance difference, write the most readable code. If it's a serious performance difference, then it's probably worth #ifdef'ing it based on profiled results under different compilers on different chips. :) -s To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
