I've built parts of LLVM itself, http://kripken.github.com/llvm.js/demo.html http://kripken.github.com/llvm.js/demo.html Which translates LLVM IR into LLVM bitcode, and then emscripten can translate to JS, all in the browser. No reason clang couldn't be compiled too, I imagine someone someday will do it when there's a need.
