#9694: Template Haskell: support other FFI calling conventions -------------------------------------+------------------------------------- Reporter: mtolly | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Template Haskell | Version: 7.8.3 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Unknown | Type of failure: Blocked By: | None/Unknown Related Tickets: | Test Case: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- In the Template Haskell syntax representations, an [https://hackage.haskell.org/package/template-haskell-2.9.0.0/docs /Language-Haskell-TH-Syntax.html#t:Callconv FFI calling convention] can currently only be CCall or StdCall. I'd like to generate code with [http://weblog.luite.com/wordpress/?p=14 GHCJS JavaScript imports], which use a "javascript" calling convention. The [http://www.haskell.org/onlinereport/haskell2010/haskellch8.html#x15-1550008.... FFI section of the Report] mentions other potential conventions, and specifically says that implementations can create new ones as appropriate, so perhaps a new constructor could be added which takes an arbitrary string? Something like: {{{ data Callconv = CCall | StdCall | Callconv String deriving( Show, Eq, Data, Typeable ) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9694 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
