#7994: Make foldl into a good consumer -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by nomeata): Despite my initial worries, this analysis is actually quite cheap: A 1.8% increase in compile time (with unchanged libraries), according to nofib (is that the best way to measure it)? Is it worth improving that at the expense of more code in GHC? E.g replace the simplifier pass after CallArity by custom one that just does eta- expansion, and only gently simplifies the expression therein? Or should I just leave it like this? -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7994#comment:17> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

That is not true anymore with the latest code (but almost so), there are a few allocation improvemts, up to `-1.3%` (in `anna`, stemming from `take 30 [... | ...]`) – not a surprise, `take` is defined with a continuation passing `takeFB :: (a -> b -> b) -> b -> a -> (Int# -> b) -> Int# -> b`. -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/7994#comment:16> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler

I guess my original testing was correct after all: At least in current Fedora the patch seems to fix the problem on i686 but not x86_64! Very weird. This at least explains the above inconsistency in my test results. Just by chance yesterday I was testing #7629 on 32bit and so by chance found this discrepancy - I normally use 64bit. I can't think of anything in the toolchain that should make a difference on 64bit to 32bit though. Anyone have any ideas? The temporary test builds are: i686: http://koji.fedoraproject.org/koji/taskinfo?taskID=6470995 x86_64: http://koji.fedoraproject.org/koji/taskinfo?taskID=6470819 (they will be garbage collected in a week). -- Ticket URL: <http://ghc.haskell.org/trac/ghc/ticket/703#comment:32> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler
