--- Comment #24 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:acf3a21cbc26b39b73c0006300f35ff017ddd6cb commit r12-4083-gacf3a21cbc26b39b73c0006300f35ff017ddd6cb Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri Oct 1 20:37:02 2021 +0100 libstdc++: Reduce header dependencies for C++20 std::erase [PR92546] This reduces the preprocessed size of <deque>, <string> and <vector> by not including <bits/stl_algo.h> for std::remove and std::remove_if. Also unwrap iterators using __niter_base, to avoid redundant debug mode checks. PR libstdc++/92546 * include/bits/erase_if.h (__erase_nodes_if): Use __niter_base to unwrap debug iterators. * include/bits/refwrap.h: Do not error if included in C++03. * include/bits/stl_algo.h (__remove_if): Move to ... * include/bits/stl_algobase.h (__remove_if): ... here. * include/std/deque (erase, erase_if): Use __remove_if instead of remove and remove_if. * include/std/string (erase, erase_if): Likewise. * include/std/vector (erase, erase_if): Likewise.
