            Bug ID: 260820
           Summary: [Wasm-GC] call_indirect should take subtyping into
                    account
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebAssembly
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: asumu at igalia.com

Currently the call_indirect signature check only succeeds if the function indices are an exact match.

Since the GC proposal introduces subtyping, this should also succeed when the target index is a supertype of the actual function being called.
