c++ - 自动生成的类成员？

Question

在创建类时，我知道有 3 个构造函数/析构函数，如果您不指定它们，它们会自动生成。 operator= 也是自动创建的。

operator== 或任何其他比较运算符是自动生成的吗？是否创建了任何其他成员或成员函数？ this 指针呢？

根据latest spec我可以找到，第 12.1 节指出:

12 Special member functions [special] 1 The default constructor (12.1), copy constructor and copy assignment operator (12.8), move constructor and move assignment operator (12.8), and destructor (12.4) are special member functions. [ Note: The implementation will implicitly declare these member functions for some class types when the program does not explicitly declare them. The implementation will implicitly define them if they are odr-used (3.2). ... ]
