Section 3.4, page 21:
"Arguments: [...]
Derived types (structures etc) and non-standard scalar types are passed in a register if and only if their memory- stored image is register-size aligned and fits into a register. [...]
All other arguments are passed by reference. The callee must copy the argument if it writes it or takes its address."
