            Bug ID: 163126
           Summary: B3 should allow Patchpoints to return more than one
                    thing.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: keith_miller at apple.com

We will likely need this for WASM in the future when WASM functions can return more than one value. One reason to do it now is that it makes a general solution to pinning registers cleaner. Each pinned value is passed to the call Patchpoint and its new value is returned afterwords.
