[dcl.fct.def.default] p1 just states:
A function that is explicitly defaulted shall
- be a special member function or a comparison operator function ([over.binary]), and
- not have default arguments.
If I don't omit some other rules, there are no more restrictions on what the comparison operator function shall satisfy.
Consider this example:
enum E{};
bool operator==(E,E) = default;
This example directly causes GCC to crash while Clang reports some diagnoses for which I cannot find the corresponding wording in the standard.
