            Bug ID: 94593
           Summary: [OpenMP] c-c++-common/gomp/requires-1.c: Missing
                    diagnostic, test-case issues
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Keywords: openmp
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org
  Target Milestone: ---

The test case c-c++-common/gomp/requires-1.c compiles with gcc/g++ -fopenmp.
But =E2=80=A6

Just that it does not get forgotten:

The last pragma:
  #pragma omp requries atomic_default_mem_order(seq_cst)

s/requrires/requires/

Additionally, CLANG rightly complains:
  error: Only one unified_shared_memory clause can appear on a requires
directive in a single translation unit

And I think clang-10 also rightly complains about the last two #pragmas:
  error: unexpected OpenMP directive '#pragma omp requires=
