Engineering Compiler Construction in Rust

Rust Impl of ECC Lang

The goal of implementing this compiler is to make it emcc compatible so that we can directly compare against LLVM optimized performance.

Getting Started

cargo build --features wasm
source init.sh # Download the wasm binary tools for the 1st time.
source setup.sh # Set up the wasm tools' environment variables.

Try it!

Assuming this is a subrepo of the write-up repo. You can try this compiler by simply typing:

./target/debug/ecc ../tests/function/01-helloworld.ecc
node ./builtins/host.js a.wasm < /dev/null

You can also use a Ctrl-D to manually pass a EOF to JS's listener, if you do not want a null-input redirection.

node ../tests/host.js a.wasm
<Ctrl-D> # Type it after seeing 'Hello world!'
