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. --- ldso/ldso/m68k/m68k_read_tp.S | 48 +++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 48 insertions(+) create mode 100644 ldso/ldso/m68k/m68k_read_tp.S (limited to 'ldso/ldso/m68k/m68k_read_tp.S') diff --git a/ldso/ldso/m68k/m68k_read_tp.S b/ldso/ldso/m68k/m68k_read_tp.S new file mode 100644 index 000000000..cb5280e67 --- /dev/null +++ b/ldso/ldso/m68k/m68k_read_tp.S @@ -0,0 +1,48 @@ +/* Copyright (C) 2010-2017 Free Software Foundation, Inc. + Contributed by Maxim Kuvyrkov , 2010. + + 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. + + In addition to the permissions in the GNU Lesser General Public + License, the Free Software Foundation gives you unlimited + permission to link the compiled version of this file with other + programs, and to distribute those programs without any restriction + coming from the use of this file.
