# make-llvm-bitcode-for-javascript

helper script that compiles llvm tools (llvm-as, llvm-dis, opt, etc.) to llvm Bitcode for later transformation into JavaScript by emscripten

## Why?

This enables you to use llvm in the browser!

## Prerequisites

You need to have emscripten installed.

## Usage

1. download or clone an llvm source tree.

        git clone [email protected]:kripken/emscripten-fastcomp.git kripken-fastcomp

   

2. run ./make-bitcode-for-javascript and provide the path to the llvm source tree

        ./make-bitcode-for-javascript.sh ../kripken-fastcomp

    

3. Wait!

4. Find .bc files in ./bitcode-for-js

```
