--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:995a740cb01a0671a2082cb1ae13d0c356d4b568 commit r11-7689-g995a740cb01a0671a2082cb1ae13d0c356d4b568 Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri Mar 12 11:47:20 2021 +0000 libstdc++: Remove symbols for new std::call_once implementation [PR 99341] This removes the new symbols added for the new futex-based std::call_once implementation. These symbols were new on trunk, so not in any released version. However, they are already present in some beta distro releases (Fedora Linux 34) and in Fedora Linux rawhide. This change can be locally reverted by distros that need to keep the symbols present until affected packages have been rebuilt. libstdc++-v3/ChangeLog: PR libstdc++/99341 * config/abi/post/aarch64-linux-gnu/baseline_symbols.txt: Remove std::once_flag symbols. * config/abi/post/ia64-linux-gnu/baseline_symbols.txt: Likewise. * config/abi/post/m68k-linux-gnu/baseline_symbols.txt: Likewise. * config/abi/post/riscv64-linux-gnu/baseline_symbols.txt: Likewise. * config/abi/pre/gnu.ver: Likewise. * src/c++11/mutex.cc [_GLIBCXX_HAVE_LINUX_FUTEX] (struct __once_flag_compat): Remove.
