             Bug #: 12056
           Summary: shared_ptr comparison to nullptr are not implemented
           Product: libc++
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
        AssignedTo: hhinnant at apple.com
        ReportedBy: dblaikie at gmail.com
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


a simple example:

#include <memory>
int main() { std::shared_ptr<int> i; i == nullptr; }

fails to compile ("invalid operands to binary expression ('shared_ptr<int>' and
'nullptr_t')").

The op== overloads were added to the summary comment in <memory> in r132261,
but the implementations were never written.
