--- Comment #3 from ktkachov at gcc dot gnu.org ---
We've received requests from some users for this builtin as well. Given the new
ranger infrastructure, would it be able to make use of the semantics of such a
builtin in a useful way? (It'd be good to see GCC eliminate some redundant
extensions, maybe threading opportunities could be improved etc)
