Research direction

Start with the attached simple C++ program and binaries for i386, x86-64, ARM, MIPS, and PPC, then examine how Binary Ninja detects vtables in read-only data and instantiates their structs. Done means users can recognize the generated C++ structures and create or view their fields through the Types window or another documented interface.

Description

Component: Core Effort: High Impact: High

When reversing C++, BinaryNinja detects the use of virtual function tables (vtables) in the read-only data section (.rodata or .data.rel.ro or whatever) and instantiates an instance of the vtable struct. However, I can't figure out how to create fields within this struct, as the type doesn't show up in the Types window, and I'm not sure of another way to add fields. I'm attaching a simple C++ program along with binaries for i386, x86-64, arm, mips, and ppc.
