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, and can also be used from JavaScript. 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 f or 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 su ch an optimization is block return value generation in SimplifyLocals).
