             Bug #: 12539
           Summary: Literal operator templates are never searched
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: llvm-bugs at quasiparticle.net
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified

The following code should compile and run by the standard (13.5.8p5), but clang
rejects it with "error: no matching literal operator for call to 'operator ""
_x' with arguments of types 'const char *' and 'unsigned long'". Adding those
parameters, in violation of the standard, causes clang to reject it because of
that same violation.

template<char... Args>
int operator"" _x()
  return 1;

int main()
  return "asdf"_x;
