  * **asm2wasm**: An asm.js-to-WebAssembly compiler, built on Emscripten's asm optimizer infrastructure. This is used by Emscripten in Binaryen mode when it uses Emscripten's fastcomp asm.js backend.
  * **wasm2asm**: A WebAssembly-to-asm.js compiler, the reverse of `asm2wasm`. This is a work in progress.
  * **s2wasm**: A compiler from the `.s` format emitted by the new WebAssembly backend being developed in LLVM. This is used by Emscripten in Binaryen mode when it integrates with the new LLVM backend.
- * **wasm.js**: A WebAssembly-to-JavaScript bridge. wasm.js contains Binaryen components compiled to JavaScript, including the interpreter, `asm2wasm`, the S-Expression parser, etc., which allow you to load WebAssembly and execute it even if the browser doesn't have native support yet. Having `asm2wasm` also gives the option to take an asm.js build and execute it as WebAssembly, which is useful for testing.

-Update your emscripten configuration file, setting the `BINARYEN_ROOT` variable to point to the directory containing binaryen.
-
-Run Emscripten's `emcc` command, passing it an additional flag:
-
-```
-emcc -s BINARYEN=1 [whatever other emcc flags you want]
-```
-
-The `BINARYEN` flag tells it to emit code using `wasm.js`, and the `BINARYEN_ROOT` config variable tells where to find `wasm.js` itself. The output `*.js` file will then contain the entire polyfill (`asm2wasm` translator + `wasm.js` interpreter). The asm.js code will be in `*.asm.js`.

 ### C/C++ Source ⇒ asm2wasm ⇒ WebAssembly
 
 When using `emcc` with the `BINARYEN` option, it will use Binaryen to build to WebAssembly. See the [emscripten wiki](https://github.com/kripken/emscripten/wiki/WebAssembly) for more details.
