--- Comment #8 from Jakub Jelinek <jakub at gcc dot gnu.org> --- It doesn't matter how it is documented, what matters is how it is implemented. E.g. can you do (__builtin_call_with_static_chain) (fn, ptr)? Or __typeof (__builtin_call_with_static_chain)? Regular builtins are what is defined in builtins.def.
