| Summary : Compiler infrastructure and toolchain library for WebAssembly
|
Description :
Binaryen is a compiler and toolchain infrastructure library for WebAssembly, written in C++. It aims to make compiling to WebAssembly easy, fast, and effective:
* Easy: Binaryen has a simple C API in a single header. It accepts input in WebAssembly-like form but also accepts a general control flow graph for compilers that prefer that.
* Fast: Binaryen\'s internal IR uses compact data structures and is designed for completely parallel codegen and optimization, using all available CPU cores. Binaryen\'s IR also compiles down to WebAssembly extremely easily and quickly because it is essentially a subset of WebAssembly.
* Effective: Binaryen\'s optimizer has many passes that can improve code very significantly (e.g. local coloring to coalesce local variables; dead code elimination; precomputing expressions when possible at compile time; etc.). These optimizations aim to make Binaryen powerful enough to be used as a compiler backend by itself. One specific area of focus is on WebAssembly-specific optimizations (that general-purpose compilers might not do), which you can think of as wasm minification, similar to minification for JavaScript, CSS, etc., all of which are language-specific (an example of such an optimization is block return value generation in SimplifyLocals).
Compilers built using Binaryen include
* asm2wasm which compiles asm.js
* s2wasm which compiles the LLVM WebAssembly\'s backend .s output format
* mir2wasm which compiles Rust MIR
Those compilers generate Binaryen IR which can then be optimized and emitted as WebAssembly (the first two use the internal C++ API, the last the C API).
Binaryen also provides a set of toolchain utilities that can
* Parse and emit WebAssembly. In particular this lets you load WebAssembly, optimize it using Binaryen, and re-emit it, thus implementing a wasm-to-wasm optimizer.
* Interpret WebAssembly as well as run the WebAssembly spec tests.
* Integrate with Emscripten in order to provide a complete compiler toolchain from C and C++ to WebAssembly.
* Polyfill WebAssembly by running it in the interpreter compiled to JavaScript, if the browser does not yet have native support (useful for testing).
