[Bug middle-end/35360] New: Static (base/offset/size rule) should be extended to handle array elements

// David Li
the two references in the loop are not aliased. Not optimized by gcc

struct A{
 int a;
 int b;
};

struct A aa[100];


void foo(int n, int i, int j)
{
  int k = 0;
  for (k = 0; k < n; k++)
  {
      aa[i].a += aa[j].b;
  }
}
