|
|
* When using global scope static initialization for simple types with virtual
|
|
* member functions, GCC creates static initializer functions. In order to
|
|
* avoid this from happening, cycle collection participants are defined as
|
|
* function tables.
|
|
*
|
|
* The Traverse function may require calling another function from the cycle
|
|
* collection participant function table, so a pointer to the function table
|
|
* is given to it. Using member function pointers would be less awkward, but
|
|
* in MSVC, the size of such a member function pointer depends on the class
|
|
* the function is member of. This makes it hard to make them compatible with
|
|
* a generic function table. Moreover, static initialization of the function
|
|
* table then uses a static initializer function.
|
|
*
|
|
* Finally, it is not possible to use an initializer list for non-aggregate
|
|
* types. Separate types are thus required for static initialization. For
|
|
* convenience and to avoid repetitions that could lead to discrepancies,
|
|
* function table members for sub-types are declared independently, and
|
|
* different aggregate types are defined for static initialization.
