#14827: Recognize when inlining would create a join point -------------------------------------+------------------------------------- Reporter: ersetzen | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: JoinPoints Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): I'm too swamped to follow up why `f` doesn't get inlined on the branch, but I know that Joachim is planning to get back to loopification.
Side note: Neither the loopification branch and ghc head run faster with ghci.
The Description says that ghci is 20x faster (in 8.2.2). So in HEAD do we have the 20x fast performance in both cases (ie good), or do we have the 1x performance in both cases (ie bad)? I still don't understand why GHCi wins so big in any version. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14827#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
