--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Like this.  If that works for you it's pre-approved.  Only implements the
special-case (the gmp path would probably have a lot of testsuite fallout?).
I don't have a suitable target to test this on where the path isn't optimized
away.
