This patch series provides basic offloading support for OpenMP and
OpenACC on openacc-gcc-9-branch, although OpenACC in particular is likely
to be buggy until we post follow-up fixes from our internal branch.
Further commentary is provided alongside each patch.
The series as a whole has been tested with offloading to NVPTX (no
regressions) and also with offloading to AMD GCN (results reasonable,
but not fully checked).
I will apply shortly.
Thanks,
Julian
