ARC cannot be directly supported on a platform that does not provide these entrypoints, although it may be supportable via a stub library.

Does this runtime directly support the subscripting methods?

Does this runtime provide an objc_terminate function?
This is used in handlers for exceptions during the unwind process; without it, abort() must be used in pure ObjC files.
