#13227: Loss of full laziness in mapFB -------------------------------------+------------------------------------- Reporter: simonpj | Owner: nomeata Type: bug | 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): Phab:D3067 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): I gave it a shot, but something is clearly still wrong, I get huge regressions in performance tests. I will try counting only the length of the `OneShot` prefix of `occ_one_shots` (which seems to make more sense to me). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13227#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
