Thanks for sharing this! I'm generally wondering in what shape the LLVM backend is at this stage. We've so far used Binaryen, but it seems that new WebAssembly features (SIMD, bulk mem ops) are coming to LLVM first. Would you still consider the LLVM-based wasm backend to be experimental? Also, how does it stack up in terms of performance (of the emitted WebAssembly "binary") when compared with Binaryen?
