Are you sure about that? Per my reading as detailed above, that would actually be valid, and be a no-op. (That's also what I'm asking about in <https://github.com/OpenACC/openacc-spec/issues/246>, using the very same text/example.) > - acc_map_data should use GOMP_MAP_VARS_OPENACC_ENTER_DATA instead of > forcing the refcount to infinity (i.e., making the behaviour the same as > "enter data (create)"). > > Does that match your understanding of what the behaviour should be? I still have to look into that one (which may have changed between OpenACC 2.6 and later?), but let's defer that one until later, as mentioned above.
