#3698: Bad code generated for zip/filter/filter loop --------------------------------------------+------------------------------ Reporter: rl | Owner: Type: bug | Status: closed Priority: low | Milestone: 7.6.2 Component: Compiler | Version: 6.13 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime performance bug | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: --------------------------------------------+------------------------------ Changes (by nomeata): * status: new => closed * difficulty: => Unknown * resolution: => fixed Comment: The new callarity analysis successfully eta-expands the monomorphic code. For the polymorphic code, there is nothing we can do, as guest mentions in comment:1. So I guess this can be closed. (I did not create a test case for this because these things are hard to test, and it is a standard application fo the callarity analysis, nothing tricky going on here.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3698#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
