#include "util/exception.hpp"

// This function exists to 'anchor' the class, and stop the compiler from

// copying vtable and RTTI info into every object file that includes

// this header. (Caught by -Wweak-vtables under Clang.)

// More information from the LLVM Coding Standards:

// If a class is defined in a header file and has a vtable (either it has

// virtual methods or it derives from classes with virtual methods), it must

// always have at least one out-of-line virtual method in the class. Without

// this, the compiler will copy the vtable and RTTI into every .o file that

// #includes the header, bloating .o file sizes and increasing link times.
