The 4.0 standard mandates that the default device is set per-task. libomptarget (and liboffload as far as I understand) has no notion of tasks, so implementing those functions anywhere else than libomp would be problematic.


Hmm, that wasn't really part of the discussion but anyway I now understand why this has to be done here (I was under the impression that there would only be one `default-device-var` per program).

I assume you will then call `omp_get_default_device()` from within the `libomptarget`?
