#7258: Compiling DynFlags is jolly slow -------------------------------------+------------------------------------- Reporter: simonpj | Owner: simonpj Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.1 Resolution: | Keywords: deriving-perf 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 tdammers): More data! https://ghc.haskell.org/trac/ghc/attachment/ticket/7258/ghc- large-record-types-cmm-size.png shows C-- code size growth as the number of fields grows for the same generated examples as in the other graphs. getline and getline-appl generate the exact same C--, so there's no point including both in the graph; they are the only ones that grow linearly among the "interesting" examples. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7258#comment:62 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
