#14594: 2 modules / 2500LOC takes nearly 3 minutes to build -------------------------------------+------------------------------------- Reporter: schyler | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 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 mpickering): I think the resulting program after you expand the deriving clauses to source code will be many times bigger than 2500 lines. Is there something concrete you have identified as being unexpectedly slow? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14594#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
