This patch adds std::shift_left and std::shift_right as per P0769R2. Alhough these are STL-style algos, this patch places them in <bits/ranges_algo.h> because they make use of some functions in the ranges namespace that are more easily reachable from <bits/ranges_algo.h> than from <bits/stl_algo.h>, namely ranges::next. In order to place these algos in <bits/stl_algo.h>, we would need to include <bits/range_access.h> from <bits/stl_algo.h> which would undesirably increase the size of <bits/stl_algo.h>. libstdc++-v3/ChangeLog: P0769R2 Add shift to <algorithm> * include/bits/ranges_algo.h (shift_left, shift_right): New. * testsuite/25_algorithms/shift_left/1.cc: New test. * testsuite/25_algorithms/shift_right/1.cc: New test. |

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.
