Hi all, I'm one of the developer of Hedgewars, an open source video game all written with FreePascal. Please see the full site at http://www.hedgewars.org/ One of the Hedgewars project is to make a WebGL/Javascript version of the game so that it can run in a browser. To do that we are using a tool named 'emscripten' which takes LLVM bytecode and generates Javascript, without affecting performance too much. Yes, we had to write a horribly hacked converter that took the small subset of Pascal used by Hedgewars and convert it to C (on a side node, the converter is written in Haskell) and reimplement the RTL. So, this got the job done (if you are using an old browser the demo might still work http://hedgewars.org/hwjs/hwjs.html ) but all this process is *highly* unmaintainable and very prone to breakage. So the right way (tm) to achieve this result would be to directly integrate LLVM bytecode generation inside Freepascal. I think we could make this work thanks to the Google Summer of Code! This program (*if* they announce it) basically introduces students to the world of FOSS development by having them work on projects for an open source organization during the summer. I don't know if Freepascal wants to participate on its own, but if not, if there is one or more developer willing to act as mentor for the students, Hedgewars (*if* selected) would happily allocate some of its students to work on this task and act as a "umbrella" for this project targeting Freepascal sources. Of course the students would still have to write a sensible project proposal for being accepted. What do you think of this idea?
Jonas already did some work on a LLVM code generator. You can find it in SVN: http://svn.freepascal.org/svn/fpc/branches/llvm/ So I'm sure we'll be happy to cooperate on this.
