        * gimplify.c (struct gimplify_omp_ctx): Add add_safelen1 member.
        (gimplify_bind_expr): If seeing TREE_ADDRESSABLE VLA inside of simd
        loop body, set ctx->add_safelen1 instead of making it GOVD_PRIVATE.
        (gimplify_adjust_omp_clauses): Add safelen (1) clause if
        ctx->add_safelen1 is set.

        * gcc.dg/gomp/pr78884.c: New test.
