A remix of the Quaker Oat Compiler

oatmilk -- A remix of the Quaker Oat Compiler written in Rust

A toy compiler for the Oat language from University of Pennsylvania's course CIS 341: Compilers. The original Oat compiler is written in OCaml. This is a rewrite in Rust.

The compiler uses a subset of LLVM IR, referred to as "LLVMLite".

Compilation phases

oatmilk's Issues

Constant folding

Implement constant folding

Document the syntax of the language

Change parser input type to generate spans

Change the input type to the parser to generate spans. Eg use nom_locate

Frontend

Add compiler front-end oat2llvmlite.

Dead code elimination

Implement dead code elimination

x86 AST

Implement a base x86 AST for generating x86 code

Add compilation phases chart

Add a chart to the README explaining the process of the compiler and it's current optimizations

Add CI

Add a CI setup to this repository

x86lite AST

Implementation of x86 AST necessary in order to generate an x86 backend

Add the Nom Parser

Create the Nom parser

Change Ids to use symbols

Use a symbol system instead of strings to speed up the compiler.
