/* { 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.

This looks like generic reload bug to me.
find_reloads_subreg_address is called on (subreg:SI (reg:DI 52) 4) where
reg_equiv_mem[regno] is
(mem/u:DI (plus:DI (reg:DI 12 %r12)
        (const:DI (unspec:DI [
                    (symbol_ref:DI ("b") [flags 0x40] <var_decl 0x2a97d11680 b>)
                ] 111))) [0 S8 A8])

This calls find_reloads_address on
(plus:DI (reg:DI 12 %r12)
    (const:DI (plus:DI (unspec:DI [
                    (symbol_ref:DI ("b") [flags 0x40] <var_decl 0x2a97d11680 b>)
                ] 111)
            (const_int 4 [0x4]))))
which is not valid on s390 (that MEM without the offset is not offsetable even,
but find_reloads_subreg_address tried anyway).
This later calls find_reloads_address_1 on that
(plus:DI (reg:DI 12 %r12)
    (const:DI (plus:DI (unspec:DI [
                    (symbol_ref:DI ("b") [flags 0x40] <var_decl 0x2a97d11680 b>)
                ] 111)
            (const_int 4 [0x4]))))
which sees the second PLUS operand is a CONST and find_reloads_address_1's just
the first PLUS operand and not the second.
5321            else if (code1 == CONST_INT || code1 == CONST
5322                     || code1 == SYMBOL_REF || code1 == LABEL_REF)
5323              find_reloads_address_1 (mode, orig_op0, 0, &XEXP (x, 0), opnum,
5324                                      type, ind_levels, insn);
That doesn't change anything (of course, REG %r12 is valid, the CONST is not)
and keeps this invalid MEM in the insn stream.
I wonder if find_reloads_address_1 shouldn't be called also on the CONSTs.

S390 is not a primary platform; moving target to 3.4.2.
