            Are you sure you want to change the base?
            Some commits from the old base branch may be removed from the timeline,
            and old review comments may become outdated.

    Wasmtime only supports these instructions. We should eventually use instead of the legacy instructions, but they are not allowed by default in node.

To generate Wasm code that makes use of the Stack Switching proposal, you first need to install the development version of Binaryen (or version 124 once it is released).
Then, you need to run
wasm_of_ocamlwith the--enable wasiflag:This produces some Wasm code that can be directly executed by the Wizard engine:
Note that we keep the same output convention, at least for now: a JavaScript file
foo.jsand a directoryfoo.assetscontaining the Wasm code. The JavaScript file should be useful to run the tests withnodeonce it supports this extension. It is used at the moment in #1831 to test the WASI runtime.
