--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> --- I don't see a reason for the builtin unless you want to optimization it away which should not happen with the _exlicit functions at all. Access and the other attributes for nullness should be enough for the function. Adding a builtin just is asking for trouble.
