From 23bb649090ff588e8642f0c581cfe7ce2d29c757 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 16 Dec 2017 21:01:39 +0100 Subject: m68k: add NPTL/TLS support Port over NPTL/TLS support from GNU C Library. In the first step only the slower syscall is used for TLS access. The uClibc-ng testsuite shows 79 errors, so their is room for bugfixes and improvements. --- libc/sysdeps/linux/m68k/sys/reg.h | 101 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 101 insertions(+) create mode 100644 libc/sysdeps/linux/m68k/sys/reg.h (limited to 'libc/sysdeps/linux/m68k/sys/reg.h') diff --git a/libc/sysdeps/linux/m68k/sys/reg.h b/libc/sysdeps/linux/m68k/sys/reg.h new file mode 100644 index 000000000..133c862b4 --- /dev/null +++ b/libc/sysdeps/linux/m68k/sys/reg.h @@ -0,0 +1,101 @@ +/* Copyright (C) 1998-2017 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
