Update.
1998-06-16 David S. Miller <davem@dm.cobaltmicro.com> * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_fixup_plt): During rtld bootstrap, always perform flushes as the kernel will emulate it when the underlying cpu does not implement flush. * sysdeps/unix/sysv/linux/sparc/sys/kernel_termios.h: Move... * sysdeps/unix/sysv/linux/sparc/kernel_termios.h: ...to here. * sysdeps/unix/sysv/linux/sparc/sparc32/__sigtrampoline.S: Remove. * sysdeps/unix/sysv/linux/sparc/sparc32/Makefile: No longer build trampoline code. * sysdeps/unix/sysv/linux/sparc/sparc32/clone.S (__clone): Branch to label .Lerror not __clone_syscall_error. (.Lerror): Fixup EINVAL setting. * sysdeps/unix/sysv/linux/sparc/sparc32/getgroups.c: New file. * sysdeps/unix/sysv/linux/sparc/sparc32/setgroups.c: New file. * sysdeps/unix/sysv/linux/sparc/sparc32/syscalls.list (__syscall_getgroups, __syscall_setgroups): Add. * sysdeps/unix/sysv/linux/sparc/sparc32/sigaction.c (__sigaction): Member name is k_sa_handler. Use memcpy to copy around sa_mask data. * math/math.h: Include bits/nan.h when compiling for ISO C 9x.
