Update.
2002-05-30 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/sysv/linux/Makefile [$(subdir)==misc] (sysdep_routines): Add readahead. * sysdeps/unix/sysv/linux/readahead.c: New file. * sysdeps/unix/sysv/linux/syscalls.list: Add sendfile64 syscall. * sysdeps/unix/sysv/linux/Versions: Export readahead and sendfile64. * sysdeps/unix/sysv/linux/alpha/syscalls.list: Add readahead syscall. Add sendfile64 alias to sendfile syscall. * sysdeps/unix/sysv/linux/ia64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/x86_64/syscalls.list: Likewise. * sysdeps/unix/sysv/linux/powerpc/syscalls.list: Add s_readahead syscall. * sysdeps/unix/sysv/linux/i386/sysdep.h: Use __i686.get_pc_thunk.XX special section for PIC register loading. * sysdeps/unix/sysv/linux/i386/i686/sysdep.h: Likewise. * config.h.in: Define HAVE_HIDDEN. * configure.in: Also define HAVE_HIDDEN if HAVE_PROTECTED is defined. * elf/elf.h: Correct Alpha TLS relocations according to last spec.
