	bytes below result and add tcb_offset to memsz.
	* sysdeps/ia64/dl-tls.h (__tls_get_addr): New prototype.
	* sysdeps/ia64/dl-machine.h: Include tls.h.
	(elf_machine_type_class): Return ELF_RTYPE_CLASS_PLT for TLS relocs

2003-01-12  Ulrich Drepper  <drepper@redhat.com>

	* elf/dl-close.c (_dl_close): Add several asserts.  Correct and
	simplify test for unloading.  If loader of a DSO is unloaded do not
	use its scope anymore.  Fall back to own scope and adjust opencounts.
	Fix several comments.
	* elf/dl-deps.c (_dl_map_object_deps): Always allocate memory for
	the l_searchlist, not only for l_initfini.

	* elf/dl-lookup.c (add_dependencies): Avoid creating relocation
	dependencies if objects cannot be removed.  Remove object with the
	definition as not unloadable if necessary.

	* elf/reldep6.c: Create relocation dependency before closing the first
	module.
