            Bug ID: 59658
           Summary: Document -f* flags enabled by -Og
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Keywords: documentation
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

http://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#index-O-775 documents
the -f* flags enabled by -O*. And the -f* options document their respective -O*
options which enables them.

However, for -Og this is not documented. The information can be obtained using:
  gcc -Q --help=optimizers -Og|grep enabled

It might be useful to have this information in the man page for -Og as well.
