#9628: Add Annotations to the AST to simplify source to source conversions -------------------------------------+------------------------------------- Reporter: alanz | Owner: alanz Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by alanz): Once the parameter is added to the hsSyn structures, there are two ways to work it forward. 1. Work it in as a parameter throughout all the compiler passes 2. Hard code it to SrcSpan for renamer onwards Option 1 allows tool writers to add annotations and then submit for further processing, but sprinkles the parameter variable throughout the code base. Option 2 provided the most value for tool developers. Which road? I am leaning towards working it all the way through. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9628#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
