Update.

1999-08-02  Jakub Jelinek  <jj@ultra.linux.cz>

	* sysdeps/unix/sysv/linux/sparc/sparc64/sigaction.c (__sigaction):
	Only allow rt signal frames. No SA_SIGINFO signals will have the
	siginfo_t just not filled out with SI_NOINFO code.
	* sysdeps/unix/sysv/linux/sparc/sparc64/register-dump.h
	(register_dump): Take the above change into account.
	* sysdeps/unix/sysv/linux/sparc/sparc64/sigcontextinfo.h
	(rt_signal_frame): Likewise.

	* sysdeps/unix/sysv/linux/sparc/getsysstats.c: New file.
