* Fix computation of INTX_MINGravatar Jason Gross2019-01-15
| | | | The minimum is -2^(bitwidth-1), not -2^bitwidth. Oops.
* Don't cast signed to unsigned before shiftingGravatar Jason Gross2019-01-15
| | | | | | | | | | | Unfortunately, signed->unsigned casts do not commute with shifts. We take care to only extend the range when it needs extending, now. This was previously causing issues with subborrow. We should really get proofs about casts in C semantics at some point soon. Fixes #489
* Autocompute s and c in WBW MontgomeryGravatar Jason Gross2019-01-14
This allows us to support primes which are not a power of 2. We also add p484 as an example. To support this, I added a small parser combinator library which can parse arithmetic expressions involving `()^*/+-` and decimal digits.
