What about using references as function parameters, but not using them anywhere? This would skip them.

The error is reported during regalloc, not during the verifier pass.

@bjorn3 as you said, this check happens in regalloc, not verifier. So should I add an Error variant for it? https://github.com/bytecodealliance/wasmtime/blob/master/cranelift/codegen/src/result.rs#L10

bytecodealliance/wasmtime

Standalone JIT-style runtime for WebAssembly, using Cranelift - bytecodealliance/wasmtime

I don't think that is necessary. Maybe move the error to the verifier though, as this is the kind of error emitted by the verifier.

Good point! I think a few tests actually need to be added:

for function parameters

for EBB params

for value types in signature refs

Can you add the code and tests for this, please? Thanks!

There should be an error annotation in this test, so it'd check that the verifier asserts because a ref type is used yet ref types aren't enabled, right?
