#14683: Slow compile times for Happy-generated source -------------------------------------+------------------------------------- Reporter: harpocrates | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 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 bernie): I believe this issue is causing a massive slow down in the compilation of the language-python library (https://github.com/bjpop/language-python). It used to take a couple of minutes to compile the library, now it takes 7 hours with ghc 8.2.1. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14683#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
