        * config/alpha/alpha.c (va_list_skip_additions): Check for
        POINTER_PLUS_EXPR in addition to PLUS_EXPR.
        (alpha_stdarg_optimize_hook): Look for POINTER_PLUS_EXPR instead of
        PLUS_EXPR when checking ap.__base.
        (alpha_va_start): Create POINTER_PLUS_EXPR instead of PLUS_EXPR
        when doing addition on pointer types.  Use size_int instead of
        build_int_cst.
        (alpha_gimplify_va_arg_1): Likewise, but use sizetype instead of
        ptr_type in the second operand.
