[cxx-abi-dev] string constant mangling

[Jason Merrill]

...and after adding the proposed mangling to G++, I get a multiply 
defined symbol on

template <typename T> constexpr T f(const T* p) { return p[0]; }
template<int> struct N { };
template <typename T> void g(T, N<f((const T*)"1")>) { }
template <typename T> void g(T, N<f((const T*)"2")>) { }

int main()
{
   g('1', N<'1'>());
   g('2', N<'2'>());
}
