[Frama-c-discuss] Newbie question on frama-c

Hi,

I am in need of some static code analyzer.  I need a tool which can 
track variables def/use accross function
boundary.

Following is a description of my problem:

I have a function A in which one of the incoming argument is declared as 
(uint8_t *).   Function A will assign values to this incoming argument:

int A (uint_8 *i) {   *i = 255 };

now I need to change it to (uint32_t *)

Obviously I will need to track down all places which invoke function A, 
and make changes to those
local variables, and recursively if a function B calls function A and 
pass into A B's incoming argument I will
need to track down all invocation of B as well.  Example below:



int B () {


unint_8  j;    // NEED TO CATCH THIS

A(&j);

k = *j;

}


int C (unint_8 *k)

A(k);    // NEED TO CATCH THIS

}


So the question is can I use frama-c to accomplish this?


Thanks much,


Luong
