[PATCH] D68185: [Diagnostics] Warn when class implements a copy constructor/copy assignment operator, but missing the copy assignment operator/copy constructor

[Nico Weber via Phabricator via cfe-commits]

Since https://en.cppreference.com/w/cpp/language/rule_of_three says "almost always" (note "almost") I'd say this probably belongs more in clang-tidy territory – I'm guessing false positive rate is very high for this. Can you collect some true / false positive statistics on some large open-source project (chromium, firefox, open office, …)?

Since C++11 it's rule of 0/3/5, so this should probably handle the move ctor/assign op too.
