--- Comment #3 from Thomas Schwinge <tschwinge at gcc dot gnu.org> ---
In fact, the __OFFLOAD_TABLE__ symbol (formerly known as __OPENMP_TARGET__)
should be completely removed, as it's unused. We settled on a different scheme
for passing this data.
We can't remove it from the libgomp OpenMP target interfaces (so, just pass
NULL for those, and remove its documentation in source code comments), because
that'd be an ABI change requiring a new symbol version, but we can remove it
from the libgomp OpenACC interfaces (ABI change still possible now, before the
5.0 release, thus setting P1).
