7f77ca07 3387 * testsuite/27_io/filesystem/filesystem_error/copy.cc: Fix static
3388 assertion failures with old std::string ABI.

9346fb0e 3390 * include/bits/fs_path.h (path::_List::erase): Replace both overloads
3391 with ...
3392 (path::pop_back(), path::_M_erase_from(const_iterator)): New member
3393 functions that will only erase elements at the end.
3394 * src/filesystem/std-path.cc (path::_List::_Impl::pop_back()): Define.
3395 (path::_List::_Impl::_M_erase_from(const_iterator)): Define.
3396 (path::_List::operator=(const _List&)): Use _M_erase_from(p) instead
3397 of erase(p, end()).
3398 (path::_List::pop_back()): Define.
3399 (path::_List::_M_erase_from(const_iterator)): Define.
3400 (path::operator/=(const path&)): Use pop_back to remove last component
3401 and _M_erase_from to remove multiple components.
3402 (path::_M_append(basic_string_view<value_type>)): Likewise.
3403 (path::operator+=(const path&)): Likewise.
3404 (path::_M_concat(basic_string_view<value_type>)): Likewise.
3405 (path::remove_filename()): Likewise.
3406 (path::lexically_normal()): Use _List::_Impl iterators instead of
3407 path::iterator. Use pop_back to remove components from the end. Clear
3408 trailing filename, instead of using erase(const_iterator) to remove
3409 a non-final component.
3410 * testsuite/27_io/filesystem/path/generation/normal.cc: Test
3411 additional cases.

3417
6b4a77f2 3418 * testsuite/21_strings/basic_string/modifiers/assign/char/
3419 move_assign_optim.cc: Avoid spurious failure when -fno-inline added
3420 to test flags.
