[PATCH, libgomp, openacc] Use GOMP_ASYNC_SYNC in GOACC_declare


Hi,

GOACC_enter_exit_data has this prototype:
...
void
GOACC_enter_exit_data (int device, size_t mapnum,
                       void **hostaddrs, size_t *sizes,
                       unsigned short *kinds,
                       int async, int num_waits, ...)
...

And GOACC_declare calls GOACC_enter_exit_data with async arg zero:
...
          case GOMP_MAP_DELETE:
            GOACC_enter_exit_data (device, 1, &hostaddrs[i], &sizes[i],
                                   &kinds[i], 0, 0);
...

Async arg zero means some async queue (see openacc 2.0a, 2.14.1 "async clause" for more details).

The declare directive has no async clause, so the arg should be GOMP_ASYNC_SYNC.

Tested libgomp testsuite on x86_64 with nvptx accelerator.

OK for trunk?

Thanks,
- Tom
Use GOMP_ASYNC_SYNC in GOACC_declare

Fix for PR82901 - "GOACC_declare calls GOACC_enter_exit_data with async arg 0"
