[Bug target/14532] New: s390x internal compiler error: output_operand: Cannot decompose address.

["jakub at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

/* { dg-do compile } */
/* { dg-options "-O2 -fpic" } */

struct I
{
  void *i;
  int j;
};
struct S
{
  struct S *m;
} **a;
extern char b[];
int d, e;

void bar (void *, void *, char *, int, int);
void baz (void *, int);

void
foo (void *x, struct I *y, char *z)
{
  struct S *f;
  int k = 1, l;

again:
  for (f = *a; f != (struct S *) a; f = f->m)
    {
      l = z - b;
      if (e && y)
        bar (&y->i, x, b, l, y->j);
      if (d)
        baz (x, l);
      z++;
    }
  if (k)
    {
      k = 0;
      goto again;
    }
}

Reproduceable on s390x on gcc-3_4-branch and trunk, works on 3.3 and earlier.
