4283 (basic_string::basic_string(const basic_string&, const _Alloc&)):
4285 (basic_string::basic_string(basic_string&&, const _Alloc&)):
4287 * include/bits/fs_path.h [!_GLIBCXX_USE_CXX11_ABI]: Remove special
4288 cases for old basic_string.
4289 * testsuite/21_strings/basic_string/cons/char/8.cc: Test
4290 allocator-extended constructors unconditionally. Add extra members to
4291 allocator type when using old string ABI.
4292 * testsuite/21_strings/basic_string/allocator/71964.cc: Enable test
4294 * testsuite/21_strings/basic_string/cons/wchar_t/8.cc: Likewise.

4297 -fno-inline added to test flags.
4299 * testsuite/21_strings/basic_string/requirements/
4300 explicit_instantiation/debug.cc: Remove XFAIL for old ABI.

4303 assertion failures with old std::string ABI.
4305 * include/bits/fs_path.h (path::_List::erase): Replace both overloads
4307 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
4308 functions that will only erase elements at the end.
4309 * src/filesystem/std-path.cc (path::_List::_Impl::pop_back()): Define.
4310 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
4311 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
4313 (path::_List::pop_back()): Define.
4314 (path::_List::_M_erase_from(const_iterator)): Define.
4315 (path::operator/=(const path&)): Use pop_back to remove last component
4316 and _M_erase_from to remove multiple components.
4317 (path::_M_append(basic_string_view<value_type>)): Likewise.
4318 (path::operator+=(const path&)): Likewise.
4319 (path::_M_concat(basic_string_view<value_type>)): Likewise.
4320 (path::remove_filename()): Likewise.
4321 (path::lexically_normal()): Use _List::_Impl iterators instead of
4322 path::iterator. Use pop_back to remove components from the end. Clear
4323 trailing filename, instead of using erase(const_iterator) to remove
4324 a non-final component.
4325 * testsuite/27_io/filesystem/path/generation/normal.cc: Test
4327 * testsuite/27_io/filesystem/path/generation/normal2.cc: New test.
4329 * src/filesystem/std-path.cc (path::operator+=(const path&)): Fix
4330 incorrect treatment of empty filename after trailing slash.
4331 * testsuite/27_io/filesystem/path/concat/path.cc: Test problem case.
4333 * testsuite/21_strings/basic_string/modifiers/assign/char/
4334 move_assign_optim.cc: Avoid spurious failure when -fno-inline added
4336 * testsuite/21_strings/basic_string/modifiers/assign/wchar_t/
4337 move_assign_optim.cc: Likewise.
