[Bug middle-end/27942] New: packed union doesn't make the unaligned magic on sh64-*

[kkojima at gcc dot gnu dot org]

union unaligned
{
  void *ptr;
} __attribute__((__packed__));

void *foo (void *p)
{
  return (((union unaligned *) p)->ptr);
}

is compiled to an aligned word access on sh64-*.  It was compiled
to an unaligned access before the patch
