I think the only solution is to have a way (e.g. a new GHC flag) to run dependency analysis on a single file, without transitive exploration of all its dependencies.
That sounds reasonable. It would certainly be more robust than the strategy I describe. It won't help if you have deeply nested CPP includes (you'd still rescan them each time), but I suspect that's negligible for GHC. As you say, if that flag can take multiple files at once, you could batch it, which would be a good performance improvement. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16253#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
