[Frama-c-discuss] One question about how to use Frama-c



Hi Frama-c developers and users,

I'm trying to use Frama-c to prove some programs but I'm stuck at how to
use "assigns"  to express that all the cells of a 3-d array will be changed.


Take a simple example:

int a[2][2][2];

int foo() {

  a[1][1][1] = 0;

  return 0;

}

How should I add an annotation of "assigns" the whole array ?

I've tried using "assigns \forall integer i,j,k ;..." or just "assigns a",
but none of them works because "assigns" is expecting a left value.

Regards,

Ziqing Luo
