c-c++-common/gomp/{attrs-,}metadirective-3.c: Fix expected result [PR118694]
With compilation for nvptx enabled, two issues showed up:
(a) "error: 'target' construct with nested 'teams' construct contains
directives outside of the 'teams' construct"
See PR comment 9 why this is difficult to fix.
Solution: Add dg-bogus and accept/expect the error for 'target
offload_nvptx'.
(b) The assumptions about the dump for 'target offload_nvptx' were wrong
as the metadirective was already expanded to a OMP_NEXT_VARIANT
construct such that no 'omp metadirective' was left in either case.
Solution: Check that no 'omp metadirective' is left; additionally, expect
either OMP_NEXT_VARIANT (when offload_nvptx is available) or no 'teams'
directive at all (if not).
gcc/testsuite/ChangeLog:
PR middle-end/118694
* c-c++-common/gomp/attrs-metadirective-3.c: Change to never
expect 'omp metadirective' in the dump. If !offload_nvptx, check
that no 'teams' shows up in the dump; for offload_nvptx, expect
OMP_NEXT_VARIANT and an error about directive between 'target'
and 'teams'.
* c-c++-common/gomp/metadirective-3.c: Likewise.
(cherry picked from commit 5d6ed6d604ff949b650e48fa4eaed3ec8b6489c1)
