--- Comment #5 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Tomasz Kaminski <tkami...@gcc.gnu.org>: https://gcc.gnu.org/g:f59cb28d53b62aa080da60617109440b303ceb2b commit r16-2424-gf59cb28d53b62aa080da60617109440b303ceb2b Author: Tomasz KamiÅski <tkami...@redhat.com> Date: Tue Jul 22 09:44:24 2025 +0200 libstdc++: Make testsuite_iterators constexpr and expand inplace_vector tests [PR119137] All functions in testsuite_iterators.h are now marked constexpr, targeting the earliest possible standard. Most functions use C++14 due to multi-statement bodies, with exceptions: * BoundsContainer and some constructors are C++11 compatible. * OutputContainer is C++20 due to operator new/delete usage. Before C++23, each constexpr templated function requires a constexpr -suitable instantiation. Functions delegating to _GLIBCXX14_CONSTEXPR must also be _GLIBCXX14_CONSTEXPR; e.g., forward_iterator_wrapper's constructor calling input_iterator_wrapper's constructor, or operator-> calling operator*. For classes defined C++20 or later (e.g., test_range), constexpr is applied unconditionally. PR libstdc++/119137 libstdc++-v3/ChangeLog: * testsuite/23_containers/inplace_vector/cons/from_range.cc: Run iterators and range test at compile-time. * testsuite/23_containers/inplace_vector/modifiers/assign.cc: Likewise. * testsuite/23_containers/inplace_vector/modifiers/multi_insert.cc: Likewise. * testsuite/util/testsuite_iterators.h (__gnu_test::BoundsContainer) (__gnu_test::OutputContainer, __gnu_test::WritableObject) (__gnu_test::output_iterator_wrapper, __gnu_test::input_iterator_wrapper) (__gnu_test::forward_iterator_wrapper) (__gnu_test::bidirectional_iterator_wrapper) (__gnu_test::random_access_iterator_wrapper) (__gnu_test::test_container): Add appropriate _GLIBCXXNN_CONSTEXPR macros to member functions.
