# WASC

**WASC is a WebAssembly AOT compiler**. The main purpose is to translate the WebAssembly code into machine(x86 and RISC-V) code.

How it works: [./doc/overview_en.md](./doc/overview_en.md)

# Build and test

**Ubuntu 18.04**

```sh

$ apt install llvm-9

$ git clone https://github.com/mohanson/wasc

$ cd wasc

$ ./build.sh

$ ./build_test.sh

```

An example is the best way to show how it works:

```sh

$ ./build/wasc example/echo.wasm

$ ./example/echo Hello World!

# Hello World!

```

You can find more useful examples in the `./example` and `./res/wasi`.

# Credits

- The project mainly inspired by xuejie's [article](https://xuejie.space/2020_03_03_introduction_to_ckb_script_programming_performant_wasm/), and got a lot of help from him.
