Bignum: fix bogus rewrite rule (#19345) (!4980) · Merge requests · Glasgow Haskell Compiler / GHC · GitLab

Due to a large amount of spam we do not allow new users to create repositories, they are "external" users. If you are a new user and want to create a repository, for example for forking GHC, open a new issue on ghc/ghc using the "get-verified" issue template

Sylvain Henry requested to merge hsyl20/ghc:hsyl20/bignum19345 into master Feb 11, 2021

Fix the following rule:

  "fromIntegral/Int->Natural" fromIntegral = naturalFromWord . fromIntegral

Its type wasn't constrained to Int hence #19345 (closed).
