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.
