4287 the result for RID_TYPEID. Pass true for new "wrap_locations_p"
4288 param of cp_parser_parenthesized_expression_list. When calling
4289 warn_for_memset, replace integer_zerop calls with
4290 literal_integer_zerop, eliminating the double logical negation
4291 cast to bool. Eliminate the special-casing for CONST_DECL in
4292 favor of the fold_for_warn within warn_for_memset.
4293 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
4294 param, defaulting to false. Convert "expr" to a cp_expr, and call
4295 maybe_add_location_wrapper on it when wrap_locations_p is true.
4296 (cp_parser_unary_expression): Call maybe_add_location_wrapper on
4297 the result for RID_ALIGNOF and RID_SIZEOF.

4325 * call.c (maybe_warn_class_memaccess): Add forward declaration.
4326 Change last argument from tree * to const vec<tree, va_gc> *, adjust
4327 args uses and check number of operands too. Don't strip away any
4328 nops. Use maybe_constant_value when looking for INTEGER_CST args.
4329 Deal with src argument not having pointer type. Check
4330 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
4332 (build_over_call): Call maybe_warn_class_memaccess here on the
4334 (build_cxx_call): Rather than here on converted arguments.

4366 call build_base_path with flag_delete_null_pointer_checks as nonnull
4367 instead of always false. When -fsanitize=null, call
4368 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
4369 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
4370 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
