#12415: Fancy BinIface encoding for tuples is broken for constraint tuples -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: #12357 Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- We have a special way of encoding tuple-related names in the interface file symbol table. See `Note [Symbol table representation of names]`. However, it was broken for constraint tuples by ffc21506894c7887d3620423aaf86bc6113a1071. The problem is very similar to the one which prevented us from encoding tuple type representations in #12357 (see ticket:12357#comment:31). By unwiring constraint tuples it becomes harder to identify them for special handling during serialization. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/12415 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
