From 1f52d89f2b4b5ca8dde7aa1be02bb1c658e0aa13 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20Bie=C3=9Fmann?= Date: Wed, 1 Dec 2010 00:58:35 +0100 Subject: [PATCH 1/1] arm: fixloop(): do not use r8 for relocation MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit r8 is used for global_data and should therefore be left alone! For C code the compiler flag --fixed-r8 does the job, but in assembler we need to be aware of that fact.
