	* sysdeps/ia64/fpu/libm_support.h (__libm_error_support): Add
	libc_hidden_proto.  Define to __GI___libm_error_support for
	assembly going into libc.so.
	* sysdeps/ia64/fpu/libc_libm_error.c (__libm_error_support): Add
	libc_hidden_def.

	* include/libc-symbols.h (HIDDEN_BUILTIN_JUMPTARGET): Define.
	* sysdeps/ia64/bcopy.S (bcopy): Use it for jump to memmove.

	* sysdeps/unix/sysv/linux/ia64/sysdep.S (__syscall_error): Access
