#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): If I omit `-prof`, the RTS yells at me when doing anything other than `-hT` or `-h` (what's the difference between these two anyway?). The output of `-hT` is not particularly revealing: https://pp.ipd.kit.edu/~sgraf/hs/. It's climbing to 80MB for `:` and another 100MB for `C`. Interestingly, the maximum residency is higher than the baseline, so it seems it's not possible to observe the effects we are seeing without `-hT`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9476#comment:64 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
