[Bug rtl-optimization/42617] TARGET_MEM_REF and plain INDIRECT_REFs are not handled by the RTL oracle

[rguenth at gcc dot gnu dot org]

------- Comment #7 from rguenth at gcc dot gnu dot org  2010-01-22 15:24 -------
With these patches I get for

void foo(int * __restrict__ a, int * __restrict__ b, int * __restrict__ c,
         int N)
{
  int i;
  for (i = 0; i < N; ++i)
    a[i] = b[i] + c[i];
}

and -O2 -funroll-all-loops all stores scheduled to the bottom of the loop
and all adds to the top of the loop.
