Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: bc36268a by Wolfgang Jeltsch at 2025-12-21T16:23:24-05:00 Remove unused known keys and names for type representations This removes the known-key and corresponding name variables for `TrName`, `TrNameD`, `TypeRep`, `KindRepTypeLitD`, `TypeLitSort`, and `mkTrType`, as they are apparently nowhere used in GHC’s source code. -
