[PATCH] D148924: [clang] Show error if defaulted comparions operator function is volatile or has ref-qualifier &&.

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added inline comments.


================
Comment at: clang/test/CXX/class/class.compare/class.compare.default/p1.cpp:18
   bool operator<=(const A&) const = default;
-  bool operator==(const A&) const volatile && = default; // surprisingly, OK
+  bool operator==(const A&) const && = default; // expected-error 
{{ref-qualifier '&&' is not allowed on defaulted comparison operators}}
+  bool operator>=(const A&) const volatile = default; // expected-error 
{{defaulted comparison operator function must not be volatile}}
----------------
Can we also have examples with out of line defaulting.
