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

	* string/tester.c (test_strcpy): Disable last added strcpy until
	it is fixed.

	[__ia64__] (TLS_LE, TLS_IE): Fix typos.  Add ;; at start of asm if
	gp is used early.

	* elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so):
	Ensure libc.so in DT_NEEDED.
	* sysdeps/alpha/dl-machine.h (elf_machine_rela): Move
	CHECK_STATIC_TLS before l_tls_offset use.

	* sysdeps/generic/libc-tls.c (__libc_setup_tls): If
	TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS
	segment has been found.  If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE
	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

	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.
