[GHC] #10721: GHC INLINE pragma behavior does not match docs
#10721: GHC INLINE pragma behavior does not match docs -------------------------------------+------------------------------------- Reporter: wyager | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: MacOS X specialize, inline, inlinable, | pragma | Architecture: x86_64 | Type of failure: Incorrect (amd64) | warning at compile-time Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Per https://downloads.haskell.org/~ghc/7.8.4/docs/html/users_guide/pragmas.html #specialize-pragma , I should be able to SPECIALIZE an imported function if the function is marked as INLINABLE at the definition site. While trying to debug a related issue (#10720), I tried making the original function `(••)` INLINABLE and then SPECIALIZing it at the call site. However, GHC tells me "`Warning: SPECIALISE pragma on INLINE function probably won't fire: ‘••’`". -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10721 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
