This patch gets std::is_object to dispatch to new built-in traits, __is_function and __is_reference. libstdc++-v3/ChangeLog: * include/std/type_traits (is_object): Use new built-in traits, __is_function and __is_reference. (is_object_v): Likewise. Signed-off-by: Ken Matsui <kmatsui@gcc.gnu.org> --- libstdc++-v3/include/std/type_traits | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
