Tree-ssa alias analysis does not take information about structure
fields into account.  Consequently head->using_obstack and bitmap_free
accesses in the following testcase are believed to alias, which prevents
further optimizations (load motion, unswitching) on tree level.

typedef struct bitmap_element_def
{
  unsigned int indx;
} bitmap_element;

typedef struct bitmap_head_def {
  bitmap_element *first;
  int using_obstack;
} bitmap_head;
typedef struct bitmap_head_def *bitmap;

bitmap_element *bitmap_free;

void foo (bitmap head, bitmap_element *elt)
{
  while (1)
    {
      if (head->using_obstack)
        bitmap_free = elt;
    }
}

------- Comment #4 from pinskia at gcc dot gnu dot org  2006-02-16 21:40 -------
We get:
  # bitmap_free_7 = PHI <bitmap_free_1(4), bitmap_free_6(5)>;
<L0>:;

  # bitmap_free_1 = PHI <bitmap_free_7(3), bitmap_free_2(2)>;
<L4>:;
  #   VUSE <bitmap_free_1>;
  D.1534_4 = head_3->using_obstack;
  if (D.1534_4 != 0) goto <L1>; else goto <L0>;

<L1>:;
  #   bitmap_free_6 = V_MUST_DEF <bitmap_free_1>;
  bitmap_free = elt_5;
  goto <bb 3> (<L0>);

I cannot figure out why Daniel's recent patches did not fix this one.
