Using the word backend results in different AIG output than the SAW backend. This is related, I believe, to different assumptions regarding bit-order; the word backend operates least-significant-bit-first, but the SAW backend conforms to the Cryptol 2 semantics, which is most-significant-bit-first.
There may be other related issues where bit-ordering assumptions affect the results; these should also be teased out.
