#13084: 'foreign import prim' are marked PlaySafe by the parser -------------------------------------+------------------------------------- Reporter: jberryman | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Experimenting with a {{{foreign import prim}}} in my code I noticed the generated core produces {{{__pkg_ccall_GC}}} which concerned me since I thought perhaps we were experiencing the overhead of a "safe" ccall. Reid Barton reccommended filing a report, commenting: it looks like prim imports are marked PlaySafe by the parser, which is presumably mostly ignored, and definitely ignored during code generation. But wherever it's not ignored there could be a bug see: http://stackoverflow.com/questions/41528208/why-is-there-no-foreign- import-prim-unsafe -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13084 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
