Example code
Please see attached code. When compiling with
$ clang++ -fopenmp -fopenmp-targets=x86_64-unknown-linux-gnu tuple.cpp
tuple.cpp:11:38: warning: Non-trivial type 'std::tuple<double, int>' is mapped,
only trivial types are guaranteed to be mapped correctly [-Wopenmp-target]
printf("%f, %d\n", std::get<0>(m_args), std::get<1>(m_args));
^~~~~~
tuple.cpp:29:5: note: in instantiation of member function 'S<double, int>::f'
requested here
s.f();
^
tuple.cpp:15:38: warning: Non-trivial type 'std::tuple<double, int>' is mapped,

I would also expect for line 20. Strictly speaking, it's not required but I
find it odd that Clang warns for several cases, but not for this one.
