Hi Alex,
In this case, the new optimizer actually is strictly better. Mostly because
it uses shorter instruction encodings. For example, it uses inc rbx whereas
old factor used add rbx, 1. But the old factor had a compiler pass called
"height normalization" which in some situations made it emit su
Hello, Björn! Thanks for the explanation! I've already lost hope of seeing a reply to that, but you appeared out of nowhere and saved the day. Thank you! Are you saying there was a different (better?) optimizer in the previous Factor releases? What happened to it? 17.01.2018, 22:25, "Björn Lindqvis

to stop as quickly as possible. It can't just halt anywhere but must
continue to execute until it comes to a point where it is safe to halt -- a
