I am trying to learn about IPSec layer in Linux kernel using Trace 32 ICD. For that I am trying to trace packet flow from user land to Ethernet driver. Problem I'm facing is that Trace32 is not able to display inline functions in stackframe output and therefore are jumps in my flow.

enter image description here

I am just wondering if :

a) there is a way to disable inline feature for kernel function (or in any program) in GCC.

b) there is a way to add support for inline functions in Trace32 ICD tool.

In case answer for both a & b is no then I would like to know if there exits a workaround to my problem.

My linux version: Linux (bts) 3.0.1-rt11-svn9237 #2 PREEMPT RT Fri Dec 21 09:58:42 IST 2012 armv7l GNU/Linux

My GCC version: arm-none-linux-gnueabi-gcc-4.3.3

Yes I can rebuild my kernel. I have codesourcery toolchain installed on my machine. – Satpal Parmar Jan 10 '13 at 13:04

Try to rebuild at `-O2` or lower and with `-fno-inline` option. – osgx Jan 10 '13 at 15:07
Yeah I got same info from http://gcc.gnu.org/onlinedocs/libstdc++/manual/debug.html. Will try this tomorrow. – Satpal Parmar Jan 10 '13 at 15:53
Here is long dicussion on topic but no conclusion. And they are discussing older GCC version I am note what's situation with new version : http://elinux.org/Extern_Vs_Static_Inline – Satpal Parmar Jan 10 '13 at 16:37
