From 39b1226c044a3089346cf6a969b41a2adbc1dc9e Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Fri, 23 Apr 2004 21:39:34 +0000 Subject: It turns out that asm/reg.h is missing from the 2.6.x kernel headers, which prevents libthread_db (used by gdb) from compiling. Include a copy within include/sys/user.h for mips, per what was done in glibc. --- libc/sysdeps/linux/mips/sys/user.h | 169 ++++++++++++++++++++++++++++++++++++- 1 file changed, 167 insertions(+), 2 deletions(-) (limited to 'libc/sysdeps/linux') diff --git a/libc/sysdeps/linux/mips/sys/user.h b/libc/sysdeps/linux/mips/sys/user.h index 21f7b28ca..8b21ff278 100644 --- a/libc/sysdeps/linux/mips/sys/user.h +++ b/libc/sysdeps/linux/mips/sys/user.h @@ -1,4 +1,4 @@ -/* Copyright (C) 2002 Free Software Foundation, Inc. +/* Copyright (C) 2002, 2003 Free Software Foundation, Inc.
