binaryen
A compiler and toolchain infrastructure library for WebAssembly, providing optimization, assembly, disassembly, and conversion utilities.
What is binaryen?
Binaryen is a C++ compiler and toolchain library designed to make compiling to WebAssembly easy, fast, and effective. It provides a foundational infrastructure for WebAssembly toolchains, offering utilities for optimization, transformation, and analysis of WebAssembly modules. The project focuses on WebAssembly-specific optimizations, parallel code generation, and deterministic tool outputs.
Compiler engineers and toolchain developers building or integrating WebAssembly backends for languages like C/C++, Rust, TypeScript, Haskell, and Kotlin. It is also used by projects like Emscripten, wasm-pack, and AssemblyScript that require WebAssembly optimization and transformation.
Developers choose Binaryen for its high-performance, modular infrastructure that prioritizes ease of integration and WebAssembly-specific optimizations. Its unique selling point is providing a robust set of deterministic tools and an intermediate representation close to WebAssembly, enabling efficient transformations and parallel optimization not always available in general-purpose compilers.
