Update.
1999-02-03 Jakub Jelinek <jj@ultra.linux.cz> * sysdeps/unix/sysv/linux/sparc/sparc64/pipe.S: Set branch prediction correctly. * sysdeps/unix/sysv/linux/sparc/sparc32/profil-counter.h: Signal takes a pointer to __sigcontext_t. * sysdeps/unix/sysv/linux/sparc/sparc64/syscall.S: Do a nop after retl. * sysdeps/unix/sysv/linux/sparc/sparc32/Dist: Remove fork.S.
