Unable to vectorize stream_cluster distance code

Hello,

i am unable to vectorize the stream cluster distance code through llvm. the code is as follows:

typedef struct {
float weight;
float coord;
long assign; /
number of point where this one is assigned /
float cost; /
cost of that assignment, weight*distance */
} Point;

int main()
{

clock_t begin, end; double time_spent;

float coordr[100000], coordri[100000];

for (int j=0;j<100000;j++)
{coordr[j]=j+1;
coordri[j]=2*j+1;
}
Point p1, p2;
p1.weight=2.0;
p1.coord=coordr;
p1.assign=5.0;
p1.cost=10.0;

p2.weight=5.0;
p2.coord=coordri;
p2.assign=8.0;
p2.cost=20.0;

int dim=100000;
int i;
float result=0.0;
begin = clock();
for (i=0;i<dim;i++)
result += (p1.coord[i] - p2.coord[i])*(p1.coord[i] - p2.coord[i]);

end = clock();
time_spent = (double)(end - begin) / CLOCKS_PER_SEC;

printf(“time spent in daxpy is %f \n”, time_spent);
return 0;
}

Is this llvm bug? or what is my mistake?

please help.

Thank You
