// NOTE: Itanium ABI for C++ requires Clang to generate 2 constructors types to support polymorphism:
|
|
// - C1 - Complete object constructor - constructs the complete object, including virtual base classes.
|
|
// - C2 - Base object constructor - creates the object itself and initializes data members and non-virtual base classes.
|
|
// The constructors are distinquished by C1/C2 designators in their mangled name.
