In C++1z drafts up to N4606 the constexpr keyword was missing from the detailed description of this function, despite being shown in the class synopsis. That was fixed editorially for N4618, but our implementation was not corrected to match. * include/std/optional (optional::value_or(U&&) &&): Add missing constexpr specifier. * testsuite/20_util/optional/constexpr/observers/4.cc: Check value_or for disengaged optionals and rvalue optionals. * testsuite/20_util/optional/observers/4.cc: Likewise.

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.
