#12367: Commit adding instances to GHC.Generics regression compiler performance -------------------------------------+------------------------------------- Reporter: bgamari | Owner: bgamari Type: bug | Status: patch Priority: normal | Milestone: 8.0.2 Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Generics Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2411 Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): One thing I also noticed while debugging this is that the `relevantBindings` logic in `TcErrors` appears to pull in `GHC.Generics` when generating an error, even when no relevant bindings are shown in the resulting message (and even with `-fmax-relevant-binds=0`). Judging from the comments surrounding `relevantBindings`, it sounds like this is expected behavior but I thought I'd mention it anyways. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12367#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
