From 3ac3d4e61a1de0c2d0e0d2bebf0d1b111f153f12 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Tue, 31 May 2016 20:51:29 +0200 Subject: arm: add non-assembly versions of pthread_spin_lock/pthread_spin_trylock Sync pthread_spin_lock/pthread_spin_trylock with GNU libc as it avoids any usage of deprecated SWP instruction. This allows to build uClibc-ng for ARMv8 Cortex-A53 CPU in 32 Bit mode. --- libpthread/nptl/sysdeps/arm/pthread_spin_lock.S | 30 ------------------------- 1 file changed, 30 deletions(-) delete mode 100644 libpthread/nptl/sysdeps/arm/pthread_spin_lock.S (limited to 'libpthread/nptl/sysdeps/arm/pthread_spin_lock.S') diff --git a/libpthread/nptl/sysdeps/arm/pthread_spin_lock.S b/libpthread/nptl/sysdeps/arm/pthread_spin_lock.S deleted file mode 100644 index a9c07c87d..000000000 --- a/libpthread/nptl/sysdeps/arm/pthread_spin_lock.S +++ /dev/null @@ -1,30 +0,0 @@ -/* Copyright (C) 2005 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.
