#12442: Pure unifier usually doesn't need to unify kinds -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2433 Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Status (see Phab:D2433 comment): Richard says: Please don't merge yet. When I validated, there were some hiccups, including around performance. IIRC, there were actually three performance improvements along with one regression, but I have to investigate properly. (A performance improvement is certainly not unexpected with this patch.) When I saw these problems, I prioritized other tasks, but will return to this eventually. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12442#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
