MLIR RUST TOY

Motivation

The content of this repo is a humble attempt to implement Toy tutorial using Rust.

Fortunately, MLIR framework provides a decent C API and the current project uses the MLIR C API to build a Rust wrapper around it to be able to implement the Toy language in Rust. However, some parts still require building C++ project :)

The current state of main branch corresponds to chapter 6. So curious user can play with building AST, MLIR IR as well as executing Toy language sources with and without optimizations. There are a few bugs and some optimizations are missed since they are not yet available in C API. Hopefully, they will be resolved in near future.

Building & playing

1. Make sure that you have LLVM 14.0.0 installed - at this point, this is the only compatible version
2. Build ODS description for Toy

mkdir -p ./cpp/toy/build
cd ./cpp/toy/build
cmake ..
make

3. Build and test

cargo build
cargo test

4. Run the Toy compiler

cargo run --example toy-compiler -- --filename ./testdata/reshape_opt.toy --emit mlir --opt
