Binaryen is a WebAssembly compiler toolchain and optimizer designed to transform, validate, and shrink binary modules. It provides a comprehensive intermediate representation framework that converts binary code into a single-assignment form to enable advanced program analysis and code transformation.
The project includes a specialized transformation engine that applies iterative optimization passes to increase execution speed and reduce binary size. Additionally, it functions as a transpiler that translates WebAssembly binary modules into executable JavaScript for environments that lack native runtime support.
Its broader capabilities cover binary analysis, including assembly and disassembly, and the structural modification of modules through import minification and dead-code elimination. The toolset also supports quality assurance via random module generation, fuzzer-targeted test cases, and binary testcase reduction to preserve specific execution properties or crashes.
