Hello,
in 3.1.1, we use "In the special case where the parameter type has a
non-trivial copy constructor or destructor" to force passing by reference.
It seems that for C++11, this should also include move constructors, for
the same reasons.
Currently, clang and gcc disagree on where to find 'a' in the following:
struct Tuple { int a; Tuple(Tuple&&); };
int f(Tuple t){
return t.a;
}

(I have trouble getting anything but time-outs from llvm's bugzilla)
