Hi,
This patch was previously posted here by Cesar:
https://gcc.gnu.org/ml/gcc-patches/2017-10/msg00668.html
This patch is necessary when not all objects containing offload code
are linked into the final executable, including those in static
libraries. Re-tested with offloading to nvptx. I will apply to the
openacc-gcc-9-branch shortly.
Thanks,
Julian
