Example text

On most machines, aggregate structures have an alignment constraint so that they can be efficiently loaded from and stored to memory. On my correspondent's machine, alignment of an aggregate is on a 4-byte boundary. So class Y (and Z) requires 3 bytes of padding. The result is a final size of 8. The empty virtual base class has become a common idiom of OO design under C++ (it provides a virtual interface without defining any data). In response, some recent compilers provide special handling of the empty virtual base class (see [SUN94a]).

Each implementation's support of virtual inheritance involves the need to make each virtual base class subobject's location within the derived class object available at runtime. Maintaining the integrity of this location is the compiler's responsibility. Bitwise copy semantics could result in a corruption of this location, so the compiler must intercede with its own synthesized copy constructor. For example, in the following declaration, ZooAnimal is derived as a virtual base class of Raccoon: class Raccoon : public virtual ZooAnimal { public: Raccoon() { /* private data initialization */ } Raccoon( int val ) { /* private data initialization */ } // ...

The truth of assertion 1, however, depends on the definition of class X. The truth of assertion 2, although partly dependent on the definition of class X, primarily depends on the degree of aggressive optimization provided by your C++ compiler. To turn things on their heads, one might even assert that in a high-quality C++ implementation, both assertions are always false for nontrivial definitions of class X. The rest of this subsection explains why. Explicit Initialization Given the definition X x0; the following three definitions each explicitly initialize its class object with x0: void foo_bar() { X x1( x0 ); X x2 = x0; X x3 = x( x0 ); // ...
