#10346: Cross-module SpecConstr -------------------------------------+------------------------------------- Reporter: simonpj | Owner: ak3n Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 7.10.1 Resolution: | Keywords: SpecConstr, | newcomer Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #13016 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by ak3n): I am sorry, but what is the desired behaviour? I made a simple test with modules. The first module contains the drop function, while the second one calls it. At the current moment, both versions (ghc with the patch (D3566) and ghc 8.2.1) with enabled -O2 flag optimize the function with SpecConstr pass in the first module, and substitute the call to the optimized version into the second module. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10346#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
