Doesn't targeting LLVM get you this kind of flexibility "for free"?

• exDM69 12y ago
  Yes and no. It can help with different target backends (including JavaScript, not sure about JVM or .NET) but you still have to do work to make sure that the calling conventions of your language and the target's match.

    Sure, but AFAIK many/most of the "supports Javascript" languages out there rely on emscripten, so LLVM is involved anyway. By its nature, LLVM gives you more flexibility in the long term than VMs that were intended as a final destination.
