[Bug target/40971] New: [4.4 Regression] ICE in memory_address

[jakub at gcc dot gnu dot org]

extern void bar (char *);

void
foo (int f, long a)
{
  {
    char d[32768];
    bar (d);
  }
  double b = f;
  while (a)
    {
      char c[8];
      __builtin_memcpy (c, &b, sizeof (c));
      if (*(double *) c != 2.0)
break;
    }
}

ICEs on powerpc-linux when compiled with -O -m32 -fstack-protector.
(plus:SI (reg:SI 150)
    (const_int 32764 [0x7ffc]))
is not valid memory_address_p for DFmode, because that address offsetted by 4
isn't a valid offset.
