Dominators with depth 1 seemingly doesn't demangle names

[alexcrichton]

Using twiggy-opt 0.3.0 on a wasm file as twiggy dominators -d 1 foo.wasm (trying to get all the roots of large sizes) prints out a lot of entries as func [xx]. I found this somewhat confusing because the wasm binary had the function names subsection, but it turns out that I needed to path -d 2 because it looks like in the dominator tree there's a function node which dominates the node with the function's name. Using twiggy dominators -d 2 did indeed print out the function names.

Would it be possible to have the function names come up at depth 1 as well?

I think the real fix is to get info from the name section for both the Code[n] element and the Func[n] element.

I'll start looking into this now 🐱

Taking another swing at this now, it's looking good so far 🙂
