Update.
2000-03-30  Ulrich Drepper  <drepper@redhat.com>

	Implement dynamic determination of constructor/destructor order in
	the dynamic linker.
	* elf/Versions [ld.so] (GLIBC_2.0): Remove _dl_init_next.
	(GLIBC_2.2): Add _dl_init.
	* elf/dl-close.c: Also call all destructors in FINI_ARRAY.
	r_duplist is not anymore allocated separately.  l_initfini is and
	therefore free it if necessary.
	* elf/dl-deps.c: If a searchlist has to be allocated, put all in one
	malloc block.  Otherwise allocate l_initfini list only.
	Put dependencies for the object in l_initfini list.
	Sort dependencies for the object to be loaded topologically.
	* elf/dl-fini.c: Before running the destructors sort the topologically.
	* elf/dl-init.c (_dl_init): Renamed from _dl_init_next.  Rewrite to
	call constructors instead of iterating over the pointers.  Get list of
	objects for which to run constructors from l_initfini element. Accept
	argc, argv, and env as parameters and pass them to the constructors.
	* elf/ld-load.c (_dl_map_object_from_fd): Initialize l_ldnum member
	with size of dynamic section.
	* elf/dl-open.c (dl_open_worker): Only call _dl_init instead of
	_dl_init_next and calling constructors ourself.
	* elf/dl-preinit.c (_dl_preinit): Renamed from _dl_preinit_next.
	Take argc, argv, and env as parameters and pass them to the
	constructors.  Rewrite to call all constructors and not iterate over
	the pointers.
	* elf/dynamic-link.h: Don't relocate DT_FINI_ARRAY entry.  Don't
	precompute l_initcount and l_preinitcount.
	* elf/link.h (struct link_map): Add l_ldnum member.
	Make l_phdr_allocated part of the bitfield.  Remove l_runcount,
	l_initcount, and l_preinitcount.  Add l_initfini.
	* sysdeps/generic/ldsodefs.h: Replace _dl_init_next prototype with
	one for _dl_init.
	* sysdeps/i386/dl-machine (RTLD_START): Rewrite to match new init
	function interface.
	* sysdeps/unix/sysv/linux/init-first.h: Removed.
	* sysdeps/unix/sysv/linux/Dist: Delete file here as well.
	* sysdeps/unix/sysv/linux/init-first.c [PIC]: Don't use
	SYSDEP_CALL_INIT.  Make _init a strong alias of init.  The calling
	conventions now match.

	* sysdeps/generic/libc-start.c: Calling __libc_init_first has no
	effect for shared objects.  Don't emit message and call only for
	static library.
