637f32c42159973f881522f5ff85dccc2675507c Overload std::distance and std::advance for path::iterator
Although filesystem::path::iterator is only a bidirectional iterator,
the underlying sequence has random access iterators (specifically, raw
pointers). This means std::distance and std::advance can be implemented
more efficiently than the generic versions which apply ++ and --
repeatedly.
PR libstdc++/71044 (partial)
* include/bits/fs_path.h (__path_iter_distance, __path_iter_advance):
New friend functions to implement std::distance and std::advance more
efficiently.
(distance, advance): Add overloads for path::iterator.
* testsuite/27_io/filesystem/path/itr/components.cc: Test new
overload.
