#13873: Adding a SPECIALIZE at a callsite in Main.hs is causing a regression -------------------------------------+------------------------------------- Reporter: jberryman | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1-rc2 Resolution: | Keywords: Specialise Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime | Unknown/Multiple performance bug | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by jberryman): Thanks so much for looking into this. I maybe wasn't clear in the body that the reason I filed the ticket was I assumed that GHC would try to choose the best specialization from those in scope (since my intuition was specialize pragmas behave sort of like type classes in the way they leak via `import` statements) and from whatever specializations it might perform in context. But maybe this is expected behavior, and a manual specialization will always take precedence? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13873#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
