Jonathan Wakely 5e3a1ea3d8 libstdc++: Fix missing members in std::allocator<void> The changes in `75c6a925da` were slightly incorrect, because the converting constructor should be noexcept, and the POCMA and is_always_equal traits should still be present in C++20. This fixes it, and slightly refactors the preprocessor conditions and order of members. Also add comments explaining things. The non-standard construct and destroy members added for PR 78052 can be private if allocator_traits<allocator<void>> is made a friend. libstdc++-v3/ChangeLog: * include/bits/allocator.h (allocator<void>) [C++20]: Add missing noexcept to constructor. Restore missing POCMA and is_always_equal_traits. [C++17]: Make construct and destroy members private and declare allocator_traits as a friend. * include/bits/memoryfwd.h (allocator_traits): Declare. * include/ext/malloc_allocator.h (malloc_allocator::allocate): Add nodiscard attribute. Add static assertion for LWG 3307. * include/ext/new_allocator.h (new_allocator::allocate): Add static assertion for LWG 3307. * testsuite/20_util/allocator/void.cc: Check that converting constructor is noexcept. Check for propagation traits and size_type and difference_type. Check that pointer and const_pointer are gone in C++20.		2021-05-11 16:11:01 +01:00

README

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the files whose
names start with COPYING for copying permission.  The manuals, and
some of the runtime libraries, are under different terms; see the
individual source files for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.

See http://gcc.gnu.org/bugs/ for how to report bugs usefully.

Copyright years on GCC source files may be listed using range
notation, e.g., 1987-2012, indicating that every year in the range,
inclusive, is a copyrightable year that could otherwise be listed
individually.
