Support pass to reference type arguments using the EXTERNREF #152

Open brew0722 opened 2 years ago

Closes: #151

wasm cannot easily reference external memory regions, since each instance is guaranteed to be a sandboxed region of memory. To solve this limitation, there is a feature spec that supports reference types. I am particularly interested in the EXTERNREF keyword.

But now, it seems that most of them have been introduced in a limited way only in the web environment. find the methods using in our VM.

Before this issue, the bulk_memory related issue must be resolved first. https://github.com/line/cosmwasm/issues/154
