#6084: Add stg_ap_pnnv and related call patterns ---------------------------------+------------------------------------------ Reporter: SimonMeier | Owner: simonmar Type: feature request | Status: infoneeded Priority: normal | Milestone: 7.8.1 Component: Runtime System | Version: 7.4.1 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Changes (by simonmar): * status: new => infoneeded Comment: The attached patch implements the idea I mentioned above. It makes zero difference on nofib as far as I can tell. If someone could try it on the bytestring Builder or something else that needs this optimisation and let me know the results, that would be great. I want to be sure it's a win before putting it in. Note that it only takes effect with -O2. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/6084#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
