It's great all this additions on Cranelift for supporting multi-value returns. We will update Wasmer soon to support it as well. Here's the multivalue return proposal (Phase 3 in the WebAssembly proposals): https://github.com/WebAssembly/multi-value Quick question: Is multivalue return supported in LLVM? Or said in other way ...code compiled from Rust or C/C++ will output Wasm with multivalue returns? Or only written-by-hand WebAssembly can take advantage of this at the moment? EDIT: after reading the article more thoroughly: LLVM doesn't support multivalue returns in Wasm yet. They are using Walrus to do wasm to wasm transformation from the return metadata info they have in wasm-bindgen (Rust).
