--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Well, then SRA didn't work.  The aggregate copy should have been elided and
the local 'l' should have been removed:

Released 11 names, 183.33%, removed 11 holes
foo (struct S * p)
{
  int l$i;
  int _3;

  <bb 2>:
  l$i_4 = MEM[(struct S *)p_2(D)];
  _3 = l$i_4 + 1;
  MEM[(struct S *)p_2(D)] = _3;
  return;

}

(from x86_64)

Maybe some cost oddity on arm prevents this?
