--- Comment #8 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Jeffrey Walton from comment #7) > It appears the intrinsics are not available. They are available for functions compiled for a suitable target, for instance because of -march or thanks to the target attribute (see the original report). It does not make sense to make them always available.
