Hi,

let's say I don't trust gcc info pages because they
might be outdated.  Is there a way to determine which exactly
optimizations are chosen at any -On level?  Also, what
is the maximum level of optimization?  info pages only talk
about -O3 and below, but I see people use -O6 and even -O9.

Thanks

Igor
