wasi-sdk About target *wasm32-wasip2-module*

I noticed an interesting concept in the slide of Wasm CG June 2024.

It said that add two targets in Preview 2, --target=wasm32-wasip2-component and --target=wasm32-wasip2-module. The latter is

easy to add to existing core wasm engines

I hope to get more details about that topic. Please give me a link or something else.

Hi @lum1n0us I think the idea was briefly discussed in this ticket: https://github.com/WebAssembly/WASI/issues/595 So basically the *-module is a foundational part for building the adapter, and the target in the linked discussion was called wasit2.

The primary difference between *-component and *-module in the context of the wasi-sdk IIUC is the linker (wasm-component-ld should be used to generate components, and wasm-ld for core modules). I'm not sure if those two should be a completely separate targets or one parametrized target (but I guess that's more an implementation detail).
