3288 param of cp_parser_parenthesized_expression_list. When calling

3290 literal_integer_zerop, eliminating the double logical negation
3291 cast to bool. Eliminate the special-casing for CONST_DECL in
3292 favor of the fold_for_warn within warn_for_memset.
3293 (cp_parser_parenthesized_expression_list): Add "wrap_locations_p"
3294 param, defaulting to false. Convert "expr" to a cp_expr, and call

3325 * call.c (maybe_warn_class_memaccess): Add forward declaration.
3326 Change last argument from tree * to const vec<tree, va_gc> *, adjust
3327 args uses and check number of operands too. Don't strip away any
3328 nops. Use maybe_constant_value when looking for INTEGER_CST args.
3329 Deal with src argument not having pointer type. Check
3330 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
3332 (build_over_call): Call maybe_warn_class_memaccess here on the
3334 (build_cxx_call): Rather than here on converted arguments.

3366 call build_base_path with flag_delete_null_pointer_checks as nonnull
3367 instead of always false. When -fsanitize=null, call
3368 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
3369 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
3370 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
