--- Comment #1 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
At the moment it is not supported to LTO runtime symbols (i.e. functions and
variables whose use may be synthetized by the compiler). Doing so would be
quite tricky, since we will need to recognize them and keep for possible use
later. It would however make sense.
