#13344: Core string literal patch regresses compiler performance considerably -------------------------------------+------------------------------------- Reporter: bgamari | Owner: bgamari Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): Ahh, indeed I should have looked at the interface files sooner. There are indeed more bindings here. e.g., previously in `Prelude` we had (in `--show-iface` output), {{{#!hs $trModule :: Module {- HasNoCafRefs, Strictness: m, Unfolding: (Module $trModule2 $trModule1) -} }}} Now we have, {{{#!hs $trModule1 :: TrName {- HasNoCafRefs, Strictness: m1, Unfolding: (TrNameS $trModule2) -} $trModule2 :: Addr# {- HasNoCafRefs, Unfolding: ("Prelude"#) -} }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13344#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
