        * config/gcn/gcn.c (gcn_expand_scalar_to_vector_address,
        gcn_md_reorg): Remove unused statement.
        (gcn_emutls_var_init): Add missing return - after sorry abort.
        * config/gcn/gcn.md (movdi_symbol_save_scc): Fix condition.
        * config/gcn/mkoffload.c (process_obj): Remove unused variables.
        * gimplify.c (gomp_oacc_needs_data_present): Likewise.
        (gimplify_adjust_omp_clauses): Fix condition by adding ().
        * omp-low.c (process_oacc_gangprivate_1): Comment unused
        parameter name to silence unused warning.
        * omp-sese.c (omp_sese_number, omp_sese_pseudo): Remove
        superfluous ().
        (oacc_do_neutering): Use signed int to avoid a warning.
