--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:f1e87aee5b7023fb4f5791c6869db705e18c2705 commit r14-3901-gf1e87aee5b7023fb4f5791c6869db705e18c2705 Author: Patrick Palka <ppa...@redhat.com> Date: Tue Sep 12 11:23:08 2023 -0400 libstdc++: Remove std::bind_front specialization for no bound args The specialization used by std::bind_front when there are no bound args (added by r13-4214-gcbd05ca5ab1231) seems to be mostly obsoleted by r13-5033-ge2eab3c4edb6aa which added [[no_unique_address]] to the main template's data members. What's left to consider is the compile time advantage of the specialization, which doesn't seem huge since it just avoids using tuple<> (which is an explicit specialization anyway) and expanding some pack expansions with an empty argument pack. So this patch removes this specialization; this means we have one less spot to fix the PR libstdc++/111327 perfect forwarding bug. libstdc++-v3/ChangeLog: * include/std/functional (_Bind_front0): Remove. (_Bind_front_t): Adjust.
