[Lse-tech] Help needed: GCOV - not getting HOW TO!!!

[prashanth M D <pra...@in...>]

Hello,

I got your id from google..
I have just started working on kernel code coverage project...

I have patched my kernel and i have configured the gcov kernel module suppo=
rt.
I compilied my module and i run insmod and i got my module executed.
But i am not getting the .da file in /proc/gcov/kernel for my module...
my sample module looks somthing like this,

#include<linux/module.h>
#include<linux/kernel.h>
#include<linux/config.h>

MODULE_LICENSE("GPL");

int init_module (void){


         printk("HELLO WORLD");
         return 0;
}

void cleanup_module (void){

         printk ("In cleanup module NTPL \n");

}

the commands are as follows...

1.  gcc  -D__KERNEL__ -DMODULE -DLINUX -O2 -Wall -Wstrict-prototypes=20
-fno-strict-aliasing -fno-strict-aliasing
     -c -o test.o -fprofile-arcs -ftest-coverage  test.c

2.  insmod gcov-proc.o

3.  insmod test.o

         This must generate a test.da file in /proc/gcov/kernel/=20=20
according to a manual i have but i am not
         getting this file generated...

I am using :
               kernel version linux-2.4.18
               gcc compiler version 3.0.4


Please tell me where i am going wrong.

Please help me out...

Thanking you,
