The C++ ABI From the Ground Up
summary
Explains the Itanium C++ ABI details that matter: name mangling, calling conventions, class and vtable layout, RTTI and exception wiring, and how tiny source changes change binary contracts. Demonstrates concrete breaks: adding or reordering Point members, defaulting pair destructors that switch register vs stack passing, and header-only/static ODR pitfalls. Shows controls: -fvisibility=hidden, visibility attributes, inline namespaces and key-function tricks to pin vtables, and diagnostics with nm and c++filt and abidiff (libabigail).
