3792 * parser.c (cp_parser_std_attribute_spec): When
3793 token_pair::require_open / require_close return false simply
3794 return error_mark_node, avoid duplicate cp_parser_error about
3795 expected '(' / ')', respectively.

3824 literal_integer_zerop, eliminating the double logical negation
3825 cast to bool. Eliminate the special-casing for CONST_DECL in
3826 favor of the fold_for_warn within warn_for_memset.

3859 * call.c (maybe_warn_class_memaccess): Add forward declaration.
3860 Change last argument from tree * to const vec<tree, va_gc> *, adjust
3861 args uses and check number of operands too. Don't strip away any
3862 nops. Use maybe_constant_value when looking for INTEGER_CST args.
3863 Deal with src argument not having pointer type. Check
3864 tree_fits_uhwi_p before calling tree_to_uhwi. Remove useless
3866 (build_over_call): Call maybe_warn_class_memaccess here on the
3868 (build_cxx_call): Rather than here on converted arguments.

3900 call build_base_path with flag_delete_null_pointer_checks as nonnull
3901 instead of always false. When -fsanitize=null, call
3902 ubsan_maybe_instrument_reference on the NULL reference INTEGER_CST.
3903 * cp-gimplify.c (cp_genericize_r): Don't walk subtrees of UBSAN_NULL
3904 call if the first argument is INTEGER_CST with REFERENCE_TYPE.
