From db0a052cecb5b8d5850d199b695323ab58522857 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 14 Jan 2003 01:20:41 +0000 Subject: Update. 2003-01-13 Martin Schwidefsky * sysdeps/unix/sysv/linux/s390/s390-32/pt-initfini.c: Avoid unterminated string literals. * sysdeps/unix/sysv/linux/s390/s390-64/pt-initfini.c: Likewise. 2003-01-13 Martin Schwidefsky * sysdeps/unix/sysv/linux/s390/s390-32/sysdep-cancel.h (PSEUDO): Code reordering. Move CENABLE and CDISABLE literals from PSEUDO_END to PSEUDO. (PSEUDO_END): Remove. (SINGLE_THREAD_P): Save an instruction. * sysdeps/unix/sysv/linux/s390/s390-32/vfork.S (__vfork): Add missing parameter to SINGLE_THREAD_P call. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep-cancel.h (PSEUDO): Code reordering. --- sysdeps/s390/s390-32/sysdep.h | 29 +++--- sysdeps/s390/s390-64/initfini.c | 192 ++++++++++++++++++++-------------------- sysdeps/s390/s390-64/sysdep.h | 18 ++-- 3 files changed, 116 insertions(+), 123 deletions(-) (limited to 'sysdeps/s390') diff --git a/sysdeps/s390/s390-32/sysdep.h b/sysdeps/s390/s390-32/sysdep.h index 316fc4c848..a9dac44307 100644 --- a/sysdeps/s390/s390-32/sysdep.h +++ b/sysdeps/s390/s390-32/sysdep.h @@ -82,13 +82,16 @@ #define mcount _mcount #endif -#define PSEUDO(name, syscall_name, args) \ -lose: SYSCALL_PIC_SETUP \ - JUMPTARGET(syscall_error) \ - .globl syscall_error;
