1. Yes, if you just use clang, then it can emit DWARF, and that will be valid, if you don't yourself manually run another tool after clang.
2. However, as of last night there *is* support for DWARF in binaryen, so using emscripten will work, at least in debug builds (binaryen will update the DWARF in every optimization it performs). Only in a tip of tree build for now (emsdk install tot).
