--- Comment #4 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Implementation of -mfpu=auto wasn't complete in GCC-7, which is why it isn't in
the main documentation. Some of the implementation was there though, which is
why it leaks into the --help information.
As you've noted it's fixed in gcc-8.
It's unlikely that this will be fixed on the release branch.
