Excellent, thanks!
So, I mentioned in my last post that I was unsatisifed with the way I
was loading plaintext candidates. I've attached a new patch that uses
SSE4.1 (if available) for more efficient loading. I am much more
satisfied with this, and it's good for another ~ 1 MH/s. I also did some
minor cleanup, and removed the __GNUC__ check per Solar's guidance.
