Update.
2000-10-24 Ulrich Drepper <drepper@redhat.com>
Complete revamp of the reference counter handling.
* include/link.h (struct link_map): Add l_idx field.
* elf/dl-close.c: Handle decrementing of reference counters more
correctly. If necessary decrement reference counters of dependencies
of dependencies.
* elf/dl-lookup.c (add_dependency): Only increment reference counter
of the object itself and not also its dependencies.
* elf/dl-open.c: Increment reference counters here.
* elf/dl-deps.c: Remove reference counter handling here.
* elf/dl-load.c: Likewise.
* elf/rtld.c: Adjust for _dl_map_deps not handling reference counters.
* elf/loadtest.c: Print loaded objects at the beginning.
