rarutyun marked 4 inline comments as done.
rarutyun added a comment.

Done. I decided to do it for copy-constructor and both `volatile` and non-`volatile` overload of copy-assignment. And the same is done for pointer specialization for all three methods.
================
Comment at: libcxx/include/atomic:1798
+
+ // delete explicitly in the most derived class to explicitly in the most derived class to satisfy
+ // the requirement that atomic (possibly volatile qualified) variables are not copyable

Another way to see this -- if this had been written that way from the start (and a bug report never had to be filed), would this comment be there? I don't believe so. That's sort of the point I'm trying to make.

Ok, I see your point. I also don't have the strong opinion on that. That's basically what I am doing usually for unobvious fix but probably `git blame` is one of the options.
Anyway, comment has been removed
