2319 * cvt.c (build_expr_type_conversion): Replace comparison with
2320 null_node with call to null_node_p.

2323 * mangle.c (write_expression): Skip location wrapper nodes.
2324 * parser.c (literal_integer_zerop): New function.
2325 (cp_parser_postfix_expression): Call maybe_add_location_wrapper on
2326 the result for RID_TYPEID. Pass true for new "wrap_locations_p"
2327 param of cp_parser_parenthesized_expression_list. When calling
2328 warn_for_memset, replace integer_zerop calls with
2329 literal_integer_zerop, eliminating the double logical negation
2330 cast to bool. Eliminate the special-casing for CONST_DECL in
2331 favor of the fold_for_warn within warn_for_memset.
2332 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
2333 param, defaulting to false. Convert "expr" to a cp_expr, and call
2334 maybe_add_location_wrapper on it when wrap_locations_p is true.

2336 the result for RID_ALIGNOF and RID_SIZEOF.

2364 * call.c (maybe_warn_class_memaccess): Add forward declaration.
2365 Change last argument from tree * to const vec<tree, va_gc> *, adjust
2366 args uses and check number of operands too. Don't strip away any
2367 nops. Use maybe_constant_value when looking for INTEGER_CST args.
2368 Deal with src argument not having pointer type. Check
2369 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
2371 (build_over_call): Call maybe_warn_class_memaccess here on the
2373 (build_cxx_call): Rather than here on converted arguments.

2378 * init.c (build_vec_init): Avoid building an INIT_EXPR with
2379 error_mark_node as second argument.

2405 call build_base_path with flag_delete_null_pointer_checks as nonnull
2406 instead of always false. When -fsanitize=null, call
2407 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
2408 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
2409 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
