Not untested -- but you should go grab a graduate text on compiler optimizations and familiarize yourself with the complexity of the problem. If hello_world.c showed a problem with an optimization, I guarantee it would be fixed. The current test case of holding up the entire FreeBSD kernel as showing an optimization problem doesn't cut it. If you care to trim it down to a single module showing the problem.... -- -- David (obrien@FreeBSD.org) GNU is Not Unix / Linux Is Not UniX To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
