devel/binaryen/pkg-descr

+The aim of Binaryen, a compiler and toolchain infrastructure library for
+WebAssembly, is 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 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).
