%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).
