| H A D | rbtree_augmented.h | 9f973cb3 Tue Jul 16 18:27:45 CDT 2019 Michel Lespinasse <walken@google.com> lib/rbtree: avoid generating code twice for the cached versions
As was already noted in rbtree.h, the logic to cache rb_first (or
rb_last) can easily be implemented externally to the core rbtree api.
Change the implementation to do just that. Previously the update of
rb_leftmost was wired deeper into the implmentation, but there were some
disadvantages to that - mostly, lib/rbtree.c had separate instantiations
for rb_insert_color() vs rb_insert_color_cached(), as well as rb_erase()
vs rb_erase_cached(), which were doing exactly the same thing save for
the rb_leftmost update at the start of either function.
