I looked around for other options that might benefit from
a similar clarification. I found a few inlining options that
only mention -O2 but that (according to -Q --help=optimizers)
are enabled at other levels as well. The attached patch
changes the manual to reflect that.
OK.
I committed it earlier today in r259250.
Given the large number of options I didn't take the time to
check all optimization options so there could others that could
stand to be similarly improved if we want to be 100% accurate.
If that is, in fact, what we want then we might want to script
this.
Yeah, note we now have -Og and -Ofast as well...
Right, those aren't mentioned. With so many flavors of -O does
enumerating them all for each optimization option still make
sense? I wonder if this could this be generated by some script
instead (it would probably have to be presented in the form of
a table but that might actually make things easier to find).
