#9356: scanl does not participate in stream fusion -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: bug | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: Runtime | Blocked By: performance bug | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by dfeuer): * status: new => patch Comment: Effects are generally small, but it seems to do a bit of good. The weakness is the `let`, of course. I'm still not sure we're gaining anything by trying to make this a good producer. Certainly making it a good consumer is good. I'm going to do a bit more hacking and testing. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9356#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
