#7933: JavaScript Cmm backend ---------------------------------+------------------------------------------ Reporter: bosu | Owner: bosu Type: feature request | Status: patch Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: | ---------------------------------+------------------------------------------ Comment(by luite): (sorry for messing up the formatting in the previous message) Our GHC patch so far does the following: * Add a JavaScript platform * Add a Custom Way, allowing you to generate multiple versions of the code side by side (In GHCJS we use this to build one version for the JavaScript platform, one for the native platform, for Template Haskell and native executables. * Add an override for GHC.Prim (so we can build for the 32 bit JavaScript platform on 64 bit hosts) * Add 'foreign import javascript' FFI calling convention, and a JavaScriptFFI extension that enables it, this gives us the UHC/Fay-like import patterns [https://github.com/ghcjs/ghcjs- jquery/blob/master/JavaScript/JQuery/Internal.hs example] * Add a special JSRef type (from the ghcjs-prim package) that can be passed to FFI For us, this is enough to make a working standalone compiler, and since we can have an easily updatable/cabal installable package that works on both 32 and 64 bit systems this way, we prefer this approach for at least the near future. Would you be interested in helping extend the patch for Josh, so it can be developed as a standalone compiler using the GHC API, and perhaps merge it when it has proven itself (for example by passing the relevant part of the GHC testsuite and demonstrating good performance/memory behaviour)? Feel free to contact me, or hop into #ghcjs on irc.freenode.net to discuss.
