Except that the two major ABIs (Microsoft's and the IA-64 one) don't operate like that: they operate like I described. > Meaning 'not generated there currently' or 'not > generated there even if A::~A() = default; would be written there' as this > was not meant as how it works now but what I've proposed. If you'd written A::~A() = default; there, you'd get a compilation error. > I always expected that that's the point where compiler prepares the > destructor is the point where it finds it in the code.
