            Bug ID: 88407
           Summary: [OpenACC] Correctly handle unseen async-arguments
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Keywords: openacc, patch
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tschwinge at gcc dot gnu.org
                CC: cltang at gcc dot gnu.org, jakub at gcc dot gnu.org
  Target Milestone: ---

The current implementation of "acc_async_test" does not conform to the
specification, and I've now generally asked the OpenACC technical committee
about the intended behavior of 'OpenACC "wait" directive/clause/runtime API
call with async-argument not used before'.  

This will need to be fixed on all release branches.
