Overview
|
|
================================
|
|
|
|
In July 2017, the C++ standard committee created a draft for the next version of the C++ standard, known here as "C++2a" (probably to be C++20).
|
|
|
|
This page shows the status of libc++; the status of clang's support of the language features is `here <https://clang.llvm.org/cxx_status.html#cxx2a>`__.
|
|
|
|
.. attention:: Features in unreleased drafts of the standard are subject to change.
|
|
|
|
The groups that have contributed papers:
|
|
|
|
- CWG - Core Language Working group
|
|
- LWG - Library working group
|
|
- SG1 - Study group #1 (Concurrency working group)
|
|
|
|
.. note:: "Nothing to do" means that no library changes were needed to implement this change.

.. [#note-P0202] P0202: The missing bits in P0202 are in ``copy`` and ``copy_backwards`` (and the ones that call them: ``copy_n``, ``set_union``, ``set_difference``, and ``set_symmetric_difference``). This is because the first two algorithms have specializations that call ``memmove`` which is not constexpr. See `Bug 25165 <https://bugs.llvm.org/show_bug.cgi?id=25165>`__
|
|
.. [#note-P0600] P0600: The missing bits in P0600 are in |sect|\ [mem.res.class], |sect|\ [mem.poly.allocator.class], and |sect|\ [container.node.overview].
|
|
.. [#note-P0966] P0966: It was previously erroneously marked as complete in version 8.0. See `bug 45368 <https://llvm.org/PR45368>`__.
|
|
|
|
.. [#note-P0619] P0619: Only ``std::allocator`` part is implemented.
