Description

I try,
wasm-opt -O2 --asyncify --pass-arg=asyncify-imports@env.func1 in.wasm -o out.wasm
In out.wasm, 4 asyncify function(asyncify_start_unwind, asyncify_stop_unwind, asyncify_start_rewind, asyncify_stop_rewind) were generated, but asyncify_get_state was not generated.
How to generated asyncify_get_state by wasm-opt?

Research direction

Reproduce the reported wasm-opt command with --asyncify and --pass-arg=asyncify-imports@env.func1, comparing the generated asyncify functions in out.wasm. Trace the asyncify pass entry point and its handling of the import argument to determine whether asyncify_get_state is conditional; done means establishing the supported way to generate it or confirming a missing behavior.
