        PR c/85696
        * c-omp.c (c_omp_predetermined_sharing): Return
        OMP_CLAUSE_DEFAULT_SHARED for artificial vars with integral type.

        * c-typeck.c (c_finish_omp_clauses): Don't use
        c_omp_predetermined_sharing, instead just check TREE_READONLY.

        * cp-tree.h (cxx_omp_predetermined_sharing_1): New prototype.
        * cp-gimplify.c (cxx_omp_predetermined_sharing): New wrapper around
        cxx_omp_predetermined_sharing_1.  Rename old function to ...
        (cxx_omp_predetermined_sharing_1): ... this.
        * semantics.c (finish_omp_clauses): Use cxx_omp_predetermined_sharing_1
        instead of cxx_omp_predetermined_sharing.

        * c-c++-common/gomp/pr85696.c: New test.
