#13227: Loss of full laziness in mapFB -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3067 Wiki Page: | -------------------------------------+------------------------------------- Changes (by nomeata): * status: patch => new * owner: nomeata => Comment:
According to perf.haskell.org (which does run nofib!), the only significant changes are time improvements of 3.5% for cacheprof and k-nucleotid.
Indeed, these improvements (with -2.7% resp. -4.16% for the final commit) seem to be genuine, and not just flaky measurements. :-)
Will you pursue comment:9?
Will give it a shot. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13227#comment:12 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
