Bug 277637 – [WASM] Unify error messages between typed funcrefs and GC proposals

• Status: RESOLVED
• Resolution: FIXED
• Component: WebAssembly

[David Degazio]

Some of our test expectations currently assume pretty specific error messages for when we pass a JSValue to a typed function reference with an incorrect type, such as "Funcref must be an exported wasm function" if we try to pass a reference to a function that is not a WASM function, or a null to a non-nullable function reference. With the GC proposal, all these reference typing rules are unified, and we generally report a fairly generic error message like "Argument value did not match the reference type" in these cases. I think we should unify these error messages so our tests don't expect different behavior based on if WASM GC is enabled or not, adopting something like the latter "Argument value did not match the reference type" message in all cases.
