This is the course project for Principles of Compilers.
A compiler for the decaf language is developed in Rust.
You need a nightly rust compiler. It is tested on rustc 1.38.0-nightly, there is no guarantee about any older version (I believe that a newer version won't break the code).
Run:
cargo run --bin test # for testing your implemetation using the testcase folder
# or
cargo run --bin decaf # for a command line app
The command line app (with name decaf) support the following arguments:
<input> # required, the input decaf file path
--target=<target> # required, <target> can be pa1a, pa1b, pa2, pa3, pa4, pa5
--output=<output> # optional, the output path; if not specified, it prints to stdout
