side-table
Found this project through the Youtube video "[OOPSLA] A Fast In-Place Interpreter for WebAssembly" and just realized that the idea of the side-table is pretty much the same as what I have implemented in my wasm in-place interpreter project back in 2022 (https://github.com/mbbill/Silverfir/blob/main/docs/Interpreter.md) I wrote it mostly for embedded projects because an in-place interpreter is critical for memory usage. Would love to discuss more if you don't mind. Sorry for posting here since it's not actually an issue.
No worries. Looks like we had very similar ideas. One complication is the handling of branching to labels with that have values, which is why Wizard's side table has a popcount and a valcount in each entry. Those are needed for brs but not for if and else. Currently Wizard only uses the side-table for control, but there are good reasons to use it for some other instructions as well.
