Message-ID: <511A7F2B.20308@reliableembeddedsystems.com> Date: Tue, 12 Feb 2013 19:43:07 +0200 From: Robert Berger <gmane@...iableembeddedsystems.com> To: linux-kernel <linux-kernel@...r.kernel.org>, linux-arm@...r.kernel.org Subject: gcov/lkm/arm-eabi/gcc 4.7.2 issue Hi, There seems to be an issue with gcov on kernel modules if you have an arm-eabi gcc on Linux 3.8-rc6 and previous versions. ./arm-linux-gnueabi-gcc --version arm-linux-gnueabi-gcc (GCC) 4.7.2 I followed these instructions [1], but without much success. In case I compile an out of tree kernel module with gcov enabled it can not be loaded and issues the following error: "unknown relocation: 38" I tried this patch [2] as well without success. It loads now, but still nothing useful in /sys/kernel/debug/gcov Please advise, Regards, Robert [1] http://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=blob;f=Documentation/gcov.txt;h=e7ca6478cd93d4e6422d1ae92455b347dbdf7ccb;hb=HEAD [2] http://us.generation-nt.com/answer/add-gcov-support-arm-help-207630451.html My public pgp key is available,at: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x90320BF1 ..."C treats you like a consenting adult.
