#9356: scanl does not participate in list fusion -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: bug | Status: infoneeded 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 nomeata): * status: patch => infoneeded Comment: Can you extend the patch with a bit more comments? In particular, why do you need this `tailScanl`, when with other functions, the `fooList` rule writes it back to the direct code? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9356#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
