#10918: Float once-used let binding into a recursive function -------------------------------------+------------------------------------- Reporter: nomeata | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): -------------------------------------+------------------------------------- Comment (by simonpj): Well, currently `-flate-dmd-anal` is an `-O2` thing, which also seems appropriate here. It's also possible (measure!) that a late run of arity analysis might be able to exploit information that was not available early; that might have performance benefits all by itself. That was the reason we introduced `-flate-dmd-anal`, for example. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10918#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
