--- Comment #3 from sandra at gcc dot gnu.org ---
Documentation for this option has been added on trunk.
There are several driver options, including this one, that don't include any
documentation for the --help output. I'm not sure if that was deliberate or
not, but if it's a problem, it would be worth doing a review to see what else
is missing.
