Using this code after the construction of the data dependance :


      datarefs = VEC_alloc (data_reference_p, heap, 10);
      dependence_relations = VEC_alloc (ddr_p, heap, 10 * 10);
      compute_data_dependences_for_loop (loop_nest, true, &datarefs,
                                         &dependence_relations);

      static int cnt = 0;
      char s[128];
      sprintf(s,"output%d",cnt++);
      FILE *f = fopen(s,"w");
      dump_data_references(f,datarefs);
      fclose(f);

With this program :

#include <stdio.h>

int fct(int *t);

int main()
{
    int tab[10];
    int i;

    printf("Hello World %d\n",tab[5]);

    printf("Sum is : %d\n",fct(tab));

    return 0;
}

int fct(int *t)
{
    int i=9;
    int res=0;
    int j,a,b;


    for(i=0;i<10;i++)
           for(j=i+1;j<10;j++)
              {
              a = t[j];
              b = t[i-1];
              res += b - a;
              }
    return res;
}


I got :


For the main :

(Data Ref:
  stmt:
  ref:
  base_object:
)

For fct :

(Data Ref:
  stmt: a_16 = *D.2144_15;
  ref: *D.2144_15;
  base_object:
  Access function 0: {0B, +, 1B}_2
)
