* Review comments.Gravatar David Benjamin2018-03-09
| | | | | | | Major change is porting everything to Z and using Z.div_mod_to_quot_rem which is a handy sledgehammer. Z is also a nice simplification. Dealing with subtraction is tidier, though I do have 0 <= x goals everywhere as a result.

* Prove another Barrett reduction variant.Gravatar David Benjamin2018-03-09
| | | | | | | | | | This variant comes from http://www.ridiculousfish.com/blog/posts/labor-of-division-episode-i.html. It was useful for https://boringssl-review.googlesource.com/#/c/boringssl/+/25887. TODO - Talk to Andres to figure out all the ways this could be done more cleanly. It was originally a standalone file.

* Move chained_carries' (now chained_carries_reduce)Gravatar Jason Gross2017-11-07
| | | | | | | | | | It now lives in Arithmetic.Core.B.Positional, where it belongs, rather than in Specific/.../HelperTactics. Andres notes that we probably don't need this at all, and could instead make chained_carries reduce after every index (and the spurious reductions should be no-ops). I didn't want to bother verifying this, at the moment, so I left it as-is.
