#10083: ghc: panic! (the 'impossible' happened) -------------------------------------+------------------------------------- Reporter: hedayaty | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.4 Resolution: | Keywords: hs-boot Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple crash | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ezyang): Simon and I agreed on our call that we should pursue inserting `noinline f` for any references to `f` from an `hs-boot` file. The `noinline` gets removed during `CorePrep` and as a result we won't infinitely try to unfold when we compile the module. How do we know when to insert these `noinline`s? It should happen in the typechecker or renamer, and the idea will be to mark `Id`s which come from a boot file as "boot identities"; then we know to insert `noinline`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10083#comment:27 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
