             Bug #: 11851
           Summary: clang doesn't instantiate constexpr functions where
                    necessary during overload resolution
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com

                    richard-llvm at metafoo.co.uk
    Classification: Unclassified


Testcase:

template<int x> constexpr int f() { return x; }
template<int i> void ovf(int (&x)[f<i>()]);
void f() { int x[10]; ovf<10>(x); }

As far as I can tell, this is valid C++11.
