is there the data reference for it in the datarefs array?
Zdenek
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
)
