This is RTL infrastructure problem, not target specific.

--- Comment #2 from vries at gcc dot gnu.org ---
Before parallelization, we have:
...
  doubleD.32 dataD.1837[1000];
  doubleD.32 resultsD.1836[1000];

  ...

  # VUSE <.MEM_19>
  _6 = dataD.1837[idx_18];
  _7 = _6 * 1.2199999999999999289457264239899814128875732421875e+1;
  # .MEM_8 = VDEF <.MEM_19>
  resultsD.1836[idx_18] = _7;
...

We could annotate these memory references with dependence clique information.
