Summary [Wasm-GC] Add extern.internalize/externalize
Asumu Takikawa
Reported 2023-01-23 14:15:48 PST
The extern.internalize/externalize instructions are used to explicitly convert between the externref type and values in the anyref hierarchy. https://github.com/WebAssembly/gc/blob/main/proposals/gc/MVP.md#external-conversion Currently this isn't implemented, so no anyref values can be exported externally. The conversions done by these instructions will also be implicitly used at the Wasm-JS boundary, whenever a conversion is needed by the JS API (e.g., for function calls between the languages).
