I won't even to there...

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....
