--- Comment #20 from GCC 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:5f10547e021db3a4a34382cd067668f9ef97fdeb commit r15-1551-g5f10547e021db3a4a34382cd067668f9ef97fdeb Author: Jonathan Wakely <jwak...@redhat.com> Date: Wed Jun 19 17:21:16 2024 +0100 libstdc++: Stop using std::__is_pointer in <deque> and <algorithm> [PR115497] This replaces all uses of the std::__is_pointer type trait with uses of the new __is_pointer built-in. Since the class template was only used to enable some performance optimizations for algorithms, we can use the built-in when __has_builtin(__is_pointer) is true (which is the case for GCC trunk and for current versions of Clang) and just forego the optimization otherwise. Removing the uses of std::__is_pointer means it can be removed from <bits/cpp_type_traits.h>, which is another step towards fixing PR 115497. libstdc++-v3/ChangeLog: PR libstdc++/115497 * include/bits/deque.tcc (__lex_cmp_dit): Replace __is_pointer class template with __is_pointer(T) built-in. (__lexicographical_compare_aux1): Likewise. * include/bits/stl_algobase.h (__equal_aux1): Likewise. (__lexicographical_compare_aux1): Likewise.
