Bignum: implement integerPowMod (#18427)

2020-10-02T17:52:38+00:00

Incidentally fix powModInteger which was crashing in integer-gmp for
negative exponents when the modular multiplicative inverse for the base
didn't exist. Now we compute it explicitly with integerRecipMod so that
every backend returns the same result without crashing.

Bignum: implement integerRecipMod (#18427)

Bignum: add bigNatFromWordArray

2020-09-26T09:37:23+00:00

Reimplementation of integer-gmp's byteArrayToBigNat#

Bignum: implement extended GCD (#18427)

Bignum: add missing compat import/export functions

2020-09-02T19:56:48+00:00

Bignum: add BigNat compat functions (#18613)

2020-09-01T03:06:28+00:00

Bignum: add more BigNat compat functions in integer-gmp

2020-08-05T07:59:27+00:00

Bignum: add backward compat integer-gmp functions

2020-08-05T07:59:27+00:00

Also enhance bigNatCheck# and isValidNatural test

BigNum: rename BigNat types

2020-07-07T17:56:11+00:00

Before this patch BigNat names were confusing because we had:

* GHC.Num.BigNat.BigNat: unlifted type used everywhere else
* GHC.Num.BigNat.BigNatW: lifted type only used to share static constants
* GHC.Natural.BigNat: lifted type only used for backward compatibility

After this patch we have:

* GHC.Num.BigNat.BigNat#: unlifted type
* GHC.Num.BigNat.BigNat: lifted type (reexported from GHC.Natural)

Thanks to @RyanGlScott for spotting this.

Add integer-gmp's ghc.mk and GNUmakefile to .gitignore
