Subject: gcov on beagle-xm with kernel module
Date: Thu, 07 Feb 2013 19:57:03 +0200	[thread overview]
Message-ID: <kf0pth$hu9$1@ger.gmane.org> (raw)

Hi,

I still try to use gcov on the beagle-xm on a kernel module and I'm not
sure this is the right mailing list to ask.

I just build it with the following modification to the makefile:

GCOV_PROFILE_debugfs.o := y

and it builds;)

... but as soon as I try and insmod I get the following:

insmod debugfs.ko
Error: could not insert module debugfs.ko: Invalid module format

and dmesg says:
[ 1628.759552] debugfs: unknown relocation: 38

Did anyone see something like this before here?

Apparently I'm not the only one having this kind of problem:

Does this look like a compiler bug?
