Building Intermediate Representation Optimizations for Bril ========================================================= John Wu wrote some code optimizations for Bril, a toy programming language to build intermediate code optimization. To see the implementations I built, take a look at the `bril-ocaml/` folder. Bril: A Compiler Intermediate Representation for Learning ========================================================= Bril (the Big Red Intermediate Language) is a compiler IR made for teaching [CS 6120][cs6120], a grad compilers course. It is an extremely simple instruction-based IR that is meant to be extended. Its canonical representation is JSON, which makes it easy to build tools from scratch to manipulate it. This repository contains the [documentation][docs], including the [language reference document][langref], and some infrastructure for Bril. There are some quick-start instructions below for some of the main tools, but check out the docs for more details about what's available. [docs]: https://capra.cs.cornell.edu/bril/ [langref]: https://capra.cs.cornell.edu/bril/lang/index.html [brilts]: https://github.com/sampsyo/bril/blob/master/bril-ts/bril.ts Install the Tools ----------------- ### TypeScript Compiler & IR Interpreter To install the TypeScript compiler and IR interpreter, you will need [Node][] and [Yarn][]. Go to the `bril-ts` directory and do this: $ yarn $ yarn build $ yarn link The last thing will install symlinks to the two utility programs, but they may not be in a standard location. To find where these tools were installed, run `yarn global bin`. You probably want to [add this to your `$PATH`][path]. The tools are `brili`, an interpreter, which takes a Bril program as JSON on stdin, and `ts2bril`, which compiles a TypeScript file given on the command line to Bril. [node]: https://nodejs.org/en/ [yarn]: https://yarnpkg.com/en/ [path]: https://unix.stackexchange.com/a/26059/61192 ### Text Format The parser & pretty printer for the human-editable text form of Bril are written for Python 3. To install them, you need [Flit][], so run this: $ pip install --user flit Then, go to the `bril-txt` directory and use Flit to install symlinks to the tools: $ flit install --symlink --user The tools are called `bril2json` and `bril2txt`. They also take input on stdin and produce output on stdout. [flit]: https://flit.readthedocs.io/ Tests ----- There are some tests in the `test/` directory. They use [Turnt][], which lets us write the expected output for individual commands. Install it with [pip][]: $ pip install --user turnt Then run all the tests by typing `make test`.
