| * This is similar to the lang-ml.js in JavaScript Prettify. |
| * |
| * All comments are adapted from the JavaScript Prettify. |
| * |
| * <p> Registers a language handler for LLVM. From |
| * https://gist.github.com/ndabas/2850418 |
| * |
| * |
| * To use, include prettify.js and this file in your HTML page. Then put your |
| * code in an HTML tag like <pre class="prettyprint lang-llvm">(my LLVM code)</pre> |
| * |
| * |
| * The regular expressions were adapted from: |
| * https://github.com/hansstimer/llvm.tmbundle/blob/76fedd8f50fd6108b1780c51d79fbe3223de5f34/Syntaxes/LLVM.tmLanguage |
| * |
| * http://llvm.org/docs/LangRef.html#constants describes the language grammar. |
