#11597: Optimize cmpTypeX -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: task | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler | Version: 7.10.3 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Simon and I observed that we could skip the kind-check in `cmpTypeX` if the type has no casts, which is the vastly common case. I will collect this information while checking the type and omit the kind check if possible. Putting on "highest" priority basically because this is so easy to do. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11597 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
