Jonathan Wakely ef45724acd P0646R1 Improving the Return Value of Erase-Like Algorithms I
In C++2a the remove, remove_if and unique members of std::list and
std::forward_list have been changed to return the number of elements
removed. This is an ABI change for the remove members and the
non-template unique members, so an abi-tag is used to give those symbols
new mangled names in C++2a mode. For the function templates the return
type is part of the mangled name so no abi-tag is needed.

	* include/bits/forward_list.h (__cpp_lib_list_remove_return_type):
	Define.
	(forward_list::__remove_return_type): Define typedef as size_type or
	void, according to __cplusplus value.
	(_GLIBCXX_FWDLIST_REMOVE_RETURN_TYPE_TAG): Define macro as abi-tag or
	empty, according to __cplusplus value.
	(forward_list::remove, forward_list::unique): Use typedef and macro
	to change return type and add abi-tag for C++2a.
	(forward_list::remove_if<Pred>, forward_list::unique<BinPred>): Use
	typedef to change return type for C++2a.
	* include/bits/forward_list.tcc (_GLIBCXX20_ONLY): Define macro.
	(forward_list::remove, forward_list::remove_if<Pred>)
	(forward_list::unique<BinPred>): Return number of removed elements
	for C++2a.
	* include/bits/list.tcc (_GLIBCXX20_ONLY): Define macro.
	(list::remove, list::unique, list::remove_if<Predicate>)
	(list::unique<BinaryPredicate>): Return number of removed elements
	for C++2a.
	* include/bits/stl_list.h (__cpp_lib_list_remove_return_type): Define.
	(list::__remove_return_type): Define typedef as size_type or
	void, according to __cplusplus value.
	(_GLIBCXX_LIST_REMOVE_RETURN_TYPE_TAG): Define macro as abi-tag or
	empty, according to __cplusplus value.
	(list::remove, list::unique): Use typedef and macro to change return
	type and add abi-tag for C++2a.
	(list::remove_if<Predicate>, list::unique<BinaryPredicate>): Use
	typedef to change return type for C++2a.
	* include/std/version (__cpp_lib_list_remove_return_type): Define.
	* testsuite/23_containers/forward_list/operations/
	remove_cxx20_return.cc: New.
	* testsuite/23_containers/forward_list/operations/
	unique_cxx20_return.cc: New.

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.
