Our LLDB patch (which we hopefully upstream soon), as well as the libunwindstack implementation actually takes care of all kind of PE/Coff modules, and is able to use runtime function as well, as DWARF information.

Yes, in my case I'm mostly only interested in the case with DWARF debug info in PE files. The applications I'm working with usually don't have debug information anyway and I'm trying to get stack traces and tooling support for Wine code specifically.
