std::wstring_convert and std::wbuffer_convert types are not copyable or movable, and store a plain pointer without a deleter. That means a much simpler type that just uses delete in its destructor can be used instead of std::unique_ptr. That avoids including and parsing all of <bits/unique_ptr.h> in every header that includes <locale>. It also avoids instantiating unique_ptr<C> and std::tuple<C*, default_delete<C>> when the conversion utilities are used. Signed-off-by: Jonathan Wakely <jwakely@redhat.com> libstdc++-v3/ChangeLog: * include/bits/locale_conv.h (__detail::_Scoped_ptr): Define new RAII class template. (wstring_convert, wbuffer_convert): Use __detail::_Scoped_ptr instead of unique_ptr. |

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.
