I wanted to play a little with it, debug the wasm bytecode and what not, so i set up gdb according to the docs and this is what i got:

It shows me the source code, which is fine, but what I want instead is that I want to inspect the wasm execution environment like see the wasm stack (if it has one), see the wasm bytecode instructions, etc, etc. Is this possible and if so how?
Alex Crichton (Nov 23 2023 at 06:22):I don't think we have the dwarf right now to perform debugging like that unfortunately
Ralph (Nov 23 2023 at 09:03):We're working on a dwarf wasm debugger extension here: https://marketplace.visualstudio.com/items?itemName=ms-vscode.wasm-dwarf-debugging. But we note in the repo that Rust does not yet produce the proper dwarf due to https://github.com/rustwasm/wasm-bindgen/issues/2389 where I notice that this bug has been fixed!! ooooo I'll give that a try.
Ralph (Nov 23 2023 at 09:10):this may not yet drop into the bytecode, but it will....
tabun dareka (Nov 23 2023 at 10:15):I see, thanks!
Ralph (Nov 23 2023 at 10:46):if you try that, and it doesn't do what you'd like, let us know. tag me in the repo: @squillace.
