--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
We certainly don't claim it is the exact same thing as using the noreturn
attribute, it is not.
We could in profile.c ignore edges that lead to basic blocks that start with
__builtin_unreachable () call as the first non-debug stmt after labels if it
was really important, but I'm not convinced it is.
