ghc-bignum library
ghc-bignum is a newer package that aims to replace the legacy
integer-simple and integer-gmp packages.
* it supports several backends. In particular GMP is still supported and
most of the code from integer-gmp has been merged in the "gmp"
backend.
* the pure Haskell "native" backend is new and is much faster than the
previous pure Haskell implementation provided by integer-simple
* new backends are easier to write because they only have to provide a
few well defined functions. All the other code is common to all
backends. In particular they all share the efficient small/big number
distinction previously used only in integer-gmp.
* backends can all be tested against the "native" backend with a simple
Cabal flag. Backends are only allowed to differ in performance, their
results should be the same.
* Add `integer-gmp` compat package: provide some pattern synonyms and
function aliases for those in `ghc-bignum`. It is intended to avoid
breaking packages that depend on `integer-gmp` internals.
