It's invalid, but:

$ cat /tmp/tmp6bcpvo3j.i
typedef long long a __attribute__ ((__vector_size__ (16)));
a b, c;
a
d ()
{
  return __builtin_ia32_aesenc128 (b, c);
}

$  gcc /dev/null -maes -mno-sse2 /tmp/tmp6bcpvo3j.i
/tmp/tmp6bcpvo3j.i: In function ‘d’:
/tmp/tmp6bcpvo3j.i:6:10: internal compiler error: in copy_to_mode_reg, at
explow.c:612
   return __builtin_ia32_aesenc128 (b, c);
