--- Comment #28 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:ac73c944eac88f37db2767aa4acc7ff6f4983f21 commit r12-7699-gac73c944eac88f37db2767aa4acc7ff6f4983f21 Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Mar 17 16:45:43 2022 +0000 libstdc++: Reduce header dependencies from PSTL headers [PR92546] This avoids including the whole of <functional> in <algorithm>, as the <pstl/glue_algorithm_defs.h> header only actually needs std::pair. This also avoids including <iterator> in <pstl/utils.h>, which only needs <type_traits>, std::bad_alloc, and std::terminate (which can be repalced with std::__terminate). This matters less, because <pstl/utils.h> is only included by the <pstl/*_impl.h> headers and they all use <iterator> anyway, and are only included by <execution>. libstdc++-v3/ChangeLog: PR libstdc++/92546 * include/pstl/glue_algorithm_defs.h: Replace <functional> with <bits/stl_pair.h>. * include/pstl/utils.h: Replace <iterator> with <type_traits>.
