#14001: Inlining does not work between modules -------------------------------------+------------------------------------- Reporter: danilo2 | Owner: (none) Type: bug | Status: new Priority: high | Milestone: Component: Compiler | Version: 8.0.2 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): I'm confused. In Matthew's repro case, * Function `(.)` is defined in module `A` and not exported. * So far as I can see, it is inlined at all its call sites in `A`. * The comment says that adding a bang to one of `(.)`'s arguments makes a big perf difference. That does not sound like a bug to me. Can someone explain what the problem is? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14001#comment:7 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
