#12364: Demand analysis for sum types -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): Yes, we implemented it with @jmct and it worked fine in our tests. Only problem is: We don't have a recursive type check, so for lists etc. it takes really long time (because it iterates 20 times as that's the hard- coded hard-limit for demand analysis iterations, specified in DmdAnal.hs). We also implemented CPR if you need that... -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12364#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
