#13270: Make Core Lint faster -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 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: -------------------------------------+------------------------------------- Not using `-dcore-lint` makes the validate build 25% faster overall. See https://perf.haskell.org/ghc/#compare/639e702b6129f501c539b158b982ed8489e3d0.... We should at least profile it and check for anything egregiously inefficient. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13270 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
#13270: Make Core Lint faster -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 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 simonpj): That ''is'' a bit of a surprise. I suppose it could be that Lint forces some thunks that would otherwise do un-forced. So it could perhaps not be Lint itself.
