<snip>>Could you share why it matters to you if there is a linkage stack entry (whether before or after getting to the "true routine", even if my guess is right about what you think of as the "true routines")?
Performance. </snip> That doesn't provide much insight. What the callable services stub and the service do is generally the business of the stub and the service. For all I know, there is a BAKR on the front end and the target routine relies on being able to extract caller information from the linkage stack. It remains up to a caller to meet the interface requirements.
