Update.
2003-08-30 Jakub Jelinek <jakub@redhat.com> * sysdeps/generic/sysdep.h (cfi_window_save, CFI_WINDOW_SAVE): Define. * sysdeps/unix/sysv/linux/sparc/bits/setjmp.h: Allow file to be included multiple times. * sysdeps/unix/sysv/linux/sparc/sparc32/clone.S (__clone): Pass ptid, tls, ctid arguments to the kernel. * sysdeps/unix/sysv/linux/sparc/sparc32/getpagesize.c (__getpagesize): Use INTERNAL_SYSCALL instead of __syscall_getpagesize. * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (__libc_sigaction): Use INLINE_SYSCALL instead of __syscall_rt_sigaction. * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list (__syscall_getgroups, __syscall_getpagesize, __syscall__llseek, __syscall_setfsgid, __syscall_setfsuid, __syscall_setgid, __syscall_setgroups, __syscall_setregid, __syscall_setreuid, __syscall_ipc, __syscall_setuid, __syscall_rt_sigaction, __syscall_rt_sigpending, __syscall_rt_sigprocmask, __syscall_rt_sigqueueinfo, __syscall_rt_sigsuspend, __syscall_rt_sigtimedwait): Remove unneeded syscall stubs. * sysdeps/unix/sysv/linux/sparc/sparc32/Makefile (sysdep_routines): Remove rt_sigsuspend, rt_sigprocmask, rt_sigtimedwait, rt_sigqueueinfo, rt_sigaction and rt_sigpending. * sysdeps/unix/sysv/linux/sparc/sparc32/sysdep.h (__CLONE_SYSCALL_STRING): Define. * sysdeps/unix/sysv/linux/sparc/sparc32/socket.S (__socket): Add CFI directives. * sysdeps/unix/sysv/linux/sparc/sparc64/sysdep.h (__CLONE_SYSCALL_STRING): Define. * sysdeps/unix/sysv/linux/sparc/sysdep.h (INLINE_CLONE_SYSCALL): Define. * sysdeps/unix/sysv/linux/sparc/system.c: New file. * sunrpc/rpc/clnt.h: Remove a few __THROW. * sunrpc/Makefile (CFLAGS-auth_unix.c): Add -fexceptions.
