sandra at gcc dot gnu.org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |sandra at gcc dot gnu.org Resolution|--- |FIXED --- 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.
