#11970: Simplify Parent for patten synonyms -------------------------------------+------------------------------------- Reporter: simonpj | Owner: mpickering Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Replying to [comment:3 mpickering]:
I have looked a bit at this. The problem from last time is that when renaming exports we need to reject data constructors if they are exported with a type constructor which is not their parent.
As I mention above, I think this would best be done in `tcExports`, which is where you reject pattern synonyms that are exported with a type constructor that is not their parent. Would that solve it? I think it might make the `rnExport` code quite a bit simpler. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11970#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
