`not implemented` when translating wasm -> luau

[ssynical]

Hi,

I've built ffmpeg.wasm and tried to run it through a build of wasm2luau.exe.

Now, when I try to actually do that; it spits out the wasm2luau runtime and errors with

thread 'main' panicked at wasm-ast\src\factory.rs:617:18:
not implemented

Wondering if this is a wasm problem, or something i've done wrong. Respective lines in factory.rs (from this repo) are:

                let data = Statement::MemoryCopy(MemoryCopy {
                    destination,
                    source,
                    size,
                });

Thanks.

It appears you might be using a different version than either the latest release or the main branch. I don't see otherwise why that line would be panicking, since it doesn't call any of the panic macros.

Built again from source on a different device, now getting the runtime and this error:

thread 'main' panicked at wasm-ast\src\factory.rs:646:18:
Unsupported instruction: I32x4Splat

This is currently the latest release. Thank you.

I'm not trying to be facetious, but what would you need ffmpeg in luau for? I don't even think the features compile to luau exist let alone are implemented in Wasynth, can't you just use the wasm version of it or just the binary?

Not an issue to be curious. I wanted to make a box parser in Luau, and seeing how the source would read data (in terms of the buffer library) would have helped me a lot at the time of commenting. At present, I'm already finished with it.
