#9476: Implement late lambda-lifting -------------------------------------+------------------------------------- Reporter: simonpj | Owner: sgraf Type: feature request | Status: closed Priority: normal | Milestone: 8.8.1 Component: Compiler | Version: 7.8.2 Resolution: fixed | Keywords: LateLamLift Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #8763 #13286 | Differential Rev(s): Phab:D5224 Wiki Page: LateLamLift | -------------------------------------+------------------------------------- Comment (by sgraf): I'd like to give bibliographical profiling a try, but enabling profiling seems to get rid of the effects: No difference in residency anymore. If completely disable closure growth checks (not just for the particular hot loop), residency worsens. Runtime also is consistently worse. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9476#comment:62 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
