--- Comment #5 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:3ec1d76a359542ed4c8370390efa9ee9e25e757f commit r14-1645-g3ec1d76a359542ed4c8370390efa9ee9e25e757f Author: Jonathan Wakely <jwak...@redhat.com> Date: Thu Jun 8 12:19:26 2023 +0100 libstdc++: Improve tests for emplace member of sequence containers Our existing tests for std::deque::emplace, std::list::emplace and std::vector::emplace are poor. We only have compile tests for PR 52799 and the equivalent for a const_iterator as the insertion point. This fails to check that the value is actually inserted correctly and the right iterator is returned. Add new tests that cover the existing 52799.cc and const_iterator.cc compile-only tests, as well as verifying the effects are correct. libstdc++-v3/ChangeLog: * testsuite/23_containers/deque/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/deque/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/list/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/list/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/vector/modifiers/emplace/52799.cc: Removed. * testsuite/23_containers/vector/modifiers/emplace/const_iterator.cc: Removed. * testsuite/23_containers/deque/modifiers/emplace/1.cc: New test. * testsuite/23_containers/list/modifiers/emplace/1.cc: New test. * testsuite/23_containers/vector/modifiers/emplace/1.cc: New test.
