           Summary: OpenACC: use of accelerator constant/read-only memory
                    for "readonly" modifier mappings
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgomp
          Assignee: unassigned at gcc dot gnu.org
          Reporter: chunglin.tang at gmail dot com
                CC: jakub at gcc dot gnu.org
  Target Milestone: ---

The readonly modifier starting from OpenACC 2.7 likely is intended to be used
to utilize for example CUDA constant memory. This hasn't been implemented yet,
marking as enhancement TBD.
