osa1, perhaps you would care to say a few words about the status of
#14259: Worker/Wrapper for sum return -------------------------------------+------------------------------------- Reporter: jheek | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: UnboxedSums Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #12364 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by osa1): these? Sure. CPR and worker/wrapper are easy to implement and I even have patches for these. (all of which should be up on phabricator) Demand analysis on the other hand is not that easy to extend (conceptually) and implement. We had some work on this too but we couldn't finish it (after several weeks of work) and these days I unfortunately don't have time & energy to work on this ;-( -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14259#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
