            Bug ID: 254694
           Summary: [Wasm-GC] Implement br_on_cast and br_on_cast_fail
           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 JSC implements the cast operations ref.cast and ref.test, but does not implement the control versions br_on_cast and br_on_cast_fail.

Note: the validation for these instructions is going to change slightly in the near future I believe (https://github.com/WebAssembly/gc/pull/359/)
