...and since Canqun reported 2.5% improvement on SPEC CFP2000 on ia64 with 
his current patch, I really think we should consider it.

We all know how hard it is to get this kind of improvement on any of the 
SPECs -- and in fact improving the current optimizers will make raise the
bar for the new ones. ;-)

Question is: who is going review/potentially approve this patch?
