There are a lot that creates pseudo C code from asm, because there is less information that is lost.
Ok, usally a C code is also a C++ code, but this is not what we want.
We know that the sofware has been written in C++, so we would like to get back the extra information that is in the source code.

There are some key points (vptr, dynamic_cast, static initialization...) that makes it possible to discover some of the original C++ structures.

I haven't heard about a tool that tries this.

Just an example for a code that works differently in an old version of C and in C++ :
