            Bug ID: 181439
           Summary: WebAssembly exported functions are named incorrectly
           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: littledan at chromium.org

The WebAssembly JS API specifies that the `name` property of exported function objects is the index where they are initially defined. For host functions, this is the index where they were imported. In running a test [1] in JSC, it seems that ordinary WebAssembly functions are given the name "" and functions which are based on a host function are given the name of that host function. On the other hand, V8 and SpiderMonkey both use index-based names.
