Subject: [PATCH v8 0/6] c++, libstdc++: get std::is_object to dispatch to new built-in traits
Date: Fri, 7 Jul 2023 22:08:07 -0700 [thread overview]
Message-ID: <20230708051137.63707-1-kmatsui@gcc.gnu.org> (raw)
In-Reply-To: <CAML+3pX+sX5mfpdRmowjtXbL-gVreB31y1UCvDuC6-j5VjuUYg@mail.gmail.com>
Hi,
This patch series gets std::is_object to dispatch to built-in traits and
implements the following built-in traits, on which std::object depends.
* __is_reference
* __is_function
* __is_void
std::is_object was depending on them with disjunction and negation.
__not_<__or_<is_function<_Tp>, is_reference<_Tp>, is_void<_Tp>>>::type
Therefore, this patch uses them directly instead of implementing an additional
built-in trait __is_object, which makes the compiler slightly bigger and
slower.
__bool_constant<!(__is_function(_Tp) || __is_reference(_Tp) || __is_void(_Tp))>
This would instantiate only __bool_constant<true> and __bool_constant<false>,
which can be mostly shared. That is, the purpose of built-in traits is
considered as achieved.
Changes in v8
* Updated the commit author to kmatsui@gcc.gnu.org considering the
expiration of my university's email address.
Ken Matsui (6):
c++: implement __is_reference built-in trait
libstdc++: use new built-in trait __is_reference for std::is_reference
c++: implement __is_function built-in trait
libstdc++: use new built-in trait __is_function for std::is_function
c++, libstdc++: implement __is_void built-in trait
libstdc++: make std::is_object dispatch to new built-in traits
