	* sysdeps/generic/ldsodefs.h (DL_DT_INIT_ADDRESS): Defined if
	ELF_FUNCTION_PTR_IS_SPECIAL is not defined.
	(DL_DT_FINI_ADDRESS): Likewise.

	* sysdeps/ia64/dl-lookupcfg.h (_dl_lookup_address): Set the
	return type to ElfW(Addr).
	(_dl_function_address): New prototype.
	(DL_FUNCTION_ADDRESS): Defined.
	(DL_DT_INIT_ADDRESS): Defined as DL_FUNCTION_ADDRESS.
	(DL_DT_FINI_ADDRESS): Likewise.

	* sysdeps/ia64/Versions (GLIBC_2.2): Add _dl_function_address.

	* sysdeps/ia64/dl-machine.h (_dl_start_address): Removed.
	(ELF_MACHINE_START_ADDRESS): Changed to DL_FUNCTION_ADDRESS.

	* sysdeps/ia64/dl-symaddr.c (_dl_start_address): Renamed to ...
	(_dl_function_address): This.

	* elf/dl-fini.c (_dl_fini): Use DL_DT_FINI_ADDRESS to get the
	function pointer for DT_FINI.
	* elf/dl-close.c (_dl_close): Likewise.

	* elf/dl-init.c (_dl_init): Use DL_DT_INIT_ADDRESS to get the
	function pointer for DT_INIT.
