This removes the use of std::ref that meant that __remove_if used an indirection through the reference, which might be a pessimization. Users can always use std::ref to pass expensive predicates into erase_if, but we shouldn't do it unconditionally. We can std::move the predicate so that if it's not cheap to copy and the user didn't use std::ref, then we try to use a cheaper move instead of a copy. There's no reason that std::erase shouldn't just be implemented by forwarding to std::erase_if. I probably should have done that in r12-4083-gacf3a21cbc26b3 when std::erase started to call __remove_if directly. libstdc++-v3/ChangeLog: * include/std/deque (erase_if): Move predicate instead of wrapping with std::ref. (erase): Forward to erase_if. * include/std/inplace_vector (erase_if, erase): Likewise. * include/std/string (erase_if, erase): Likewise. * include/std/vector (erase_if, erase): 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.
