--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I think it was a serious mistake to officially add support for it when it only works on one of the 3 configurations. Unfortunately there has not really been any progress on this in the past 3 month since it has been reported, netierh from aarch64 maintainers nor upstream.
