From 27b0258934adb212b760ead998d51f8005224abc Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 3 May 2004 22:40:52 +0000 Subject: Update. 2004-04-23 Jakub Jelinek * 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. --- nptl/ChangeLog | 6 ++ nptl/sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h | 121 ++++++++++++---------- 2 files changed, 73 insertions(+), 54 deletions(-) (limited to 'nptl') diff --git a/nptl/ChangeLog b/nptl/ChangeLog index 3432b1a..078b481 100644 --- a/nptl/ChangeLog +++ b/nptl/ChangeLog @@ -1,3 +1,9 @@ +2004-04-23 Jakub Jelinek + + * sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h (SYSDEP_CANCEL_ERRNO, + SYSDEP_CANCEL_ERROR): Define. + (PSEUDO): Use it. + 2004-05-01 Jakub Jelinek * Versions (libpthread): Remove __pthread_cleanup_upto@@GLIBC_PRIVATE. diff --git a/nptl/sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h b/nptl/sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h index 2fe1c6a..a360c68 100644 --- a/nptl/sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h +++ b/nptl/sysdeps/unix/sysv/linux/ia64/sysdep-cancel.h @@ -1,4 +1,4 @@ -/* Copyright (C) 2002, 2003 Free Software Foundation, Inc. +/* Copyright (C) 2002, 2003, 2004 Free Software Foundation, Inc.
