#4470: Loop optimization: identical counters -------------------------------------+------------------------------------- Reporter: choenerzs | Owner: Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: Component: Compiler | Keywords: loop optimization Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: Runtime | Related Tickets: performance bug | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by choenerzs): It is (afaik) more than just slightly related. However, the (wanted) solutions are different. Flow fusion works within the limited context of repa by using a different intermediate system. Here, I'd like a more general solution -- since we can't express everything in terms of repa or even vector. On the other hand, I think it will be more complicated to get this done on the GHC side -- though the solution might be very worthwhile given the comments above. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4470#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
