Essentially.

You need a ChangeLog entry for the patch.  The ChangeLog must be
properly formatted and follow the rules for said entries.  You should
also say how the patch was tested.

I just entered a bug report real quick listed as "trivial":


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32532

It looks like someone already replied to commit it, so I guess I don't
have to follow up with a post to gcc-patches.  Comments?
