--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yeah. Or rather the FEs shouldn't clobber the builtin decls (_not_ merge into
them) so that when the ME looks up decls for them they never pick up user
decls.
Similar issues for builtin folding if the folded-to builtin is misdeclared.
