Description Daniel Ehrenberg 2018-01-09 09:57:11 PST 
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.
