Update.
2004-04-23 Jakub Jelinek <jakub@redhat.com> * sysdeps/ia64/fpu/libm_support.h (__libm_error_support): Add libc_hidden_proto. Define to __GI___libm_error_support for assembly going into libc.so. * sysdeps/ia64/fpu/libc_libm_error.c (__libm_error_support): Add libc_hidden_def. * include/libc-symbols.h (HIDDEN_BUILTIN_JUMPTARGET): Define. * sysdeps/ia64/bcopy.S (bcopy): Use it for jump to memmove. * sysdeps/unix/sysv/linux/ia64/sysdep.S (__syscall_error): Access gprel errno if RTLD_PRIVATE_ERRNO or __thread __libc_errno/errno if USE___THREAD.
