There are lots of issues, can take a while to find all the use cases in them (work has been ongoing for some time). But from memory I can recall that https://github.com/johnmccutchan/ecmascript_simd/issues/59 https://github.com/johnmccutchan/ecmascript_simd/issues/59 is interesting here, it mentions, among other things, the major SIMD-using code portion from an important real-world codebase (IMVU). Might also be relevant discussion on the emscripten repo, https://github.com/kripken/emscripten/issues?q=is%3Aopen+is%3Aissue+label%3ASIMD https://github.com/kripken/emscripten/issues?q=is%3Aopen+is%... as some debate happened there while implementing code generation that emits SIMD.js.
