For me, the one spot where Ghidra is lacking is support for vtables (or COM objects). You can't simply feed it a C++ header file that defines the COM object.
Is there an issue requesting that behavior? My guess is it'll be some onoz trying to ship a C++ parser but "you don't ask, you don't get" and asking on HN is not what I meant :-D
Actually, having written that out: is there vtable support and just not C++ header parsing support, or both facets are missing?
Reading the issues [0] there is a 'prototype' script "RecoverClassesFromRTTIScript.java" to rebuild vtable's, testing on a project it does indeed resolve further.
