            Bug ID: 52512
           Summary: llvm-c++filt unable to demangle void
                    f<decltype(nullptr), (decltype(nullptr))0>()
           Product: tools

          Severity: enhancement
          Priority: P

When attempting to demangle "_Z1fIDnLDn0EEvv" llvm-cxxfilt does not demangle
the input. According to GCC we should see similar to "void f<decltype(nullptr),

This was found by compiling the following:

template<class T, T t> void f() {}
typedef decltype(nullptr) nullptr_t;
template <> void f<nullptr_t, nullptr>() {}
