Ulrich Drepper adc12574e5 Update.
2003-07-30  Jakub Jelinek  <jakub@redhat.com>

	* elf/dl-reloc.c (_dl_allocate_static_tls): Don't return any value,
	call dl_signal_error directly.  If already relocated, call
	GL(dl_init_static_tls) directly, otherwise queue it for later.
	(CHECK_STATIC_TLS): Undo 2003-07-24 change.
	* elf/rtld.c (dl_main): Initialize GL(dl_init_static_tls).
	* elf/dl-open.c (dl_open_worker): Call GL_dl_init_static_tls
	for all static TLS initializations delayed in _dl_allocate_static_tls.
	* elf/dl-support.c (_dl_init_static_tls): New variable.
	* include/link.h (struct link_map): Add l_need_tls_init.
	* sysdeps/generic/ldsodefs.h (_rtld_global): Add _dl_init_static_tls.
	(_dl_nothread_init_static_tls): New prototype.
	(_dl_allocate_static_tls): Adjust prototype.

	* elf/tls-macros.h (VAR_INT_DEF): Add alignment directive.

	elf_machine_rela_relative): Adjust.
	(CHECK_STATIC_TLS): _dl_allocate_static_tls can fail now.
