static inline int
foo (int len, void *indata, void *outdata)
{
  if (len < 0 || (len & 7) != 0)
    return 0;
  if (len != 0 && indata != outdata)
    __builtin_memcpy (outdata, indata, len);
  return len;
}

static inline int
bar (int len, void *indata, void *outdata)
{
  if (len < 0 || (len & 1) != 0)
    return 0;
  if (len != 0 && indata != outdata)
    __builtin_memcpy (outdata, indata, len);
  return len;
}

int (*volatile p1) (int, void *, void *) = foo;
int (*volatile p2) (int, void *, void *) = bar;

__attribute__((noipa)) int
baz (int len, void *indata, void *outdata)
{
  if ((len & 6) != 0)
    bar (len, indata, outdata);
  else
    foo (len, indata, outdata);
}

int
main ()
{
  char buf[13] = "abcdefghijkl";
  p2 (6, buf, buf + 6);
  if (__builtin_strcmp (buf, "abcdefabcdef"))
    __builtin_abort ();
}

Reproduces the wrong range in bar, but still doesn't crash nor abort.  So I
probably need some different size of the copying.
