From ecdd1a316035312a0565a64011520819ff36ae11 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Fri, 3 Apr 1998 12:07:01 +0000 Subject: Update. 1998-04-03 16:29 Philip Blundell Based on patch from Pat Beirne: * sysdeps/unix/sysv/linux/arm/sysdep.S (__syscall_error): Same for PIC and non-PIC now. Correctly negate error number. (errno): Use `%' not `@' in .type directives. 1998-04-03 Ulrich Drepper * sysdeps/i386/strtok.S: Change to use single exit point. * sysdeps/i386/i686/strtok.S: Likewise. --- ChangeLog | 12 ++++++++++++ sysdeps/i386/i686/strtok.S | 16 ++-------------- sysdeps/i386/strtok.S | 18 +++--------------- sysdeps/unix/sysv/linux/arm/sysdep.S | 22 +++++++--------------- 4 files changed, 24 insertions(+), 44 deletions(-) diff --git a/ChangeLog b/ChangeLog index f77a0603a5..3351a173ba 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,15 @@ +1998-04-03 16:29 Philip Blundell + + Based on patch from Pat Beirne: + * sysdeps/unix/sysv/linux/arm/sysdep.S (__syscall_error): Same for + PIC and non-PIC now.
