#11375: Type aliases twice as slow to compile as closed type families. -------------------------------------+------------------------------------- Reporter: danilo2 | Owner: (none) Type: bug | Status: infoneeded Priority: high | Milestone: Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: TypeFamilies Operating System: MacOS X | Architecture: aarch64 Type of failure: Compile-time | Test Case: performance bug | Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by danilo2): @bgmari, I'm sorry, due to completely lack of time while moving to new back-end architecture, we didn't hunted it down and it stopped slowing us down. Let's close this issue, as fast as it appears again, I'll prepare minimal example. I'm really sorry I did not cut it down that time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11375#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
