From 3116126871400c8737a9df0145f66534f097c06c Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 18 Mar 1998 14:42:25 +0000 Subject: Update. 1998-03-18 14:25 Ulrich Drepper * string/bits/string2.h: Add optimization for strdup. Always define __strsep and __strtok_r and make real names available when feature select macros are defined. 1998-03-18 Andreas Jaeger * manual/install.texi (Installation): Use i486-linux as example instead of the unsupported sunos4. (Reporting Bugs): Mention glibcbug script. (Tools for Installation): gcc 2.8.1/egcs 1.0.2 is required. 1998-03-16 Andreas Schwab * posix/wordexp-tst.sh: Make portable. Add more tests. * posix/Makefile (do-globtest do-wordexp-test): New targets. 1998-03-18 13:38 Ulrich Drepper * sysdeps/unix/sysv/linux/libc-start.c: Moved to ... * sysdeps/generic/libc-start.c: ...here, replacing former content. * sysdeps/unix/sysv/linux/Dist: Add netash/ash.h and netpacket/packet.h. * sysdeps/unix/sysv/linux/bits/socket.h: Pretty print. 1998-03-17 Andreas Schwab * sysdeps/unix/sysv/linux/bits/resource.h: Remove trailing comma in enumerator for strict standard compliance. * sysdeps/generic/bits/resource.h: Likewise. 1998-03-18 10:04 Philip Blundell * sysdeps/arm/sysdep.h (__ARM_USES_FP): Deleted. (PLTJMP): New macro. * sysdeps/arm/fpu/__longjmp.S: New file, implementation of longjmp() when floating point enabled. * sysdeps/arm/fpu/setjmp.S: Likewise for setjmp(). * sysdeps/arm/__longjmp.S: Remove floating point code. * sysdeps/arm/setjmp.S: Likewise. * sysdeps/arm/bsd-setjmp.S: Call __sigsetjmp by correct name. * sysdeps/arm/bsd-_setjmp.S: Likewise. * sysdeps/arm/memset.S: New file; optimised ARM implementation of memset(). * sysdeps/generic/setsockopt.c (setsockopt): Keep in step with prototype. 1998-03-17 16:16 Philip Blundell Based on patches from Pat Beirne and Scott Bambrough: * sysdeps/arm/__longjmp.S: Use ip, not r2, as temporary. * sysdeps/arm/bits/fenv.h: New file. * sysdeps/arm/dl-machine.h: New file. Add ELF support. * sysdeps/arm/elf/setjmp.S: Likewise. * sysdeps/arm/elf/start.S: Likewise. * sysdeps/arm/init-first.c: Likewise. * sysdeps/arm/setjmp.S: Call __sigjmp_save through PLT * sysdeps/arm/sysdep.h: Change format of .type directive. Correct comment about floating point to reflect current reality. * sysdeps/unix/arm/brk.S: Support PIC. * sysdeps/unix/arm/sysdep.S (syscall_error): Support PIC and re-entrant code. * sysdeps/unix/sysv/linux/arm/socket.S: Check correctly for error return; call syscall_error through PLT. * sysdeps/unix/sysv/linux/arm/sysdep.h (ENTRY): Correct error jump. 1998-03-04 12:01 Philip Blundell * sysdeps/unix/sysv/linux/netpacket/packet.h: New file. * sysdeps/unix/sysv/linux/netash/ash.h: Likewise. * sysdeps/unix/sysv/linux/Makefile (sysdep_headers): Install them. --- sysdeps/unix/arm/brk.S | 19 ++++++++++++++++--- sysdeps/unix/arm/sysdep.S | 36 +++++++++++++++++++++++++++++++++--- 2 files changed, 49 insertions(+), 6 deletions(-) (limited to 'sysdeps/unix/arm') diff --git a/sysdeps/unix/arm/brk.S b/sysdeps/unix/arm/brk.S index 0150bcd..b3924a3 100644 --- a/sysdeps/unix/arm/brk.S +++ b/sysdeps/unix/arm/brk.S @@ -1,4 +1,4 @@ -/* Copyright (C) 1991, 1992, 1993, 1995, 1997 Free Software Foundation, Inc. +/* Copyright (C) 1991, 92, 93, 95, 97, 98 Free Software Foundation, Inc.
