#9370: unfolding info as seen when building a module depends on flags in a previously-compiled module -------------------------------------+------------------------------------- Reporter: carter | Owner: richardfung Type: bug | Status: new Priority: high | Milestone: 8.2.1 Component: Compiler | Version: 7.8.3 Resolution: | Keywords: newcomer, | Inlining Operating System: Unknown/Multiple | Architecture: Type of failure: Compile-time | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #8635 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by richardfung): Not really sadly.. I've been just trying to understand all the code. I started looking from where --make starts, trying to go down to where the ModInfo is actually generated. I see that mkIface_ generates the [IfaceDecl] that gets passed to addFingerprints which eventually returns the ModIface which we save and I believe reuse, but that's the farthest I've gotten; I still don't know where IfaceIdInfo is set to NoInfo. At least.. I think that's what's happening? Given the fact I haven't even started looking at the second part of this problem, checking when to inline, I'm beginning to wonder if I'm in over my head! Any advice would certainly be appreciated. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9370#comment:26 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
