--- Comment #1 from Iain Buclaw <ibuclaw at gcc dot gnu.org> ---
The libcall is still typed `void`, even though `typeof(*null)` (aka noreturn)
has existed in the language for some time now.

All libcall functions that are marked ECF_NORETURN should have their return
type updated to be noreturn as well.
