#14461: Reuse free variable lists through nested closures -------------------------------------+------------------------------------- Reporter: tdammers | Owner: alexbiehl Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: 7258 | Differential Rev(s): Wiki Page: NestedClosures | -------------------------------------+------------------------------------- Comment (by alexbiehl): Ok, compiling with optimizations somewhat reduces the amount of updatable thunks. Possibly because of demand analysis. We must be careful to not share updatable thunks. I have to measure the impact but I suspect this will greatly reduce the effect of this transformation and we should think about a different scheme. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14461#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
