--- Comment #2 from Jim Wilson <wilson at gcc dot gnu.org> ---
I don't see any gcc regression.  I think the psABI spec was updated without
checking gcc.  Unfortunately, fixing gcc would cause a non-backward compatible
ABI change.  Given that we fixed the ABI back in January when we upstreamed
glibc, we can't change it now without causing a lot of trouble.  Hence, the
easy solution is to fix the paABI spec to match what gcc actually emits.
