            Bug ID: 22218
           Summary: Warn when trying to std::move from something that's
                    already an rvalue
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: andersca at icloud.com

    Classification: Unclassified

In WebKit we have our own WTF::move that makes calling std::move on a value
that's already an rvalue. It would be nice if clang warned on this natively
instead.
