      Description

      If an inline type is returned, its fields are passed in registers if possible. The first register (rax) either contains a pointer to the InlineKlass to allow buffering in interpreted or C1 compiled callers or an oop if the inline type has already been buffered. Currently, a C2 compiled caller completely ignores the first register.
