So the current toolchain involves using emscripten to generate asm.js and then using binaryen to convert asm.js to WebAssembly. Unfortunately emscripten depends on a fork of LLVM (FastComp), with no plans for a proper LLVM asm.js backend.<p>Are there plans for a properly WebAssembly LLVM backend that does not depend on forking LLVM (like emscripten)?
