Correct. Because most s390x instructions update CC, we gain quite a lot by delaying the computation until there is a user of the CC.


So as "likely quite useful if you're working on the instruction
emulation", is this indicative of a problem that requires attention or
is simply normal processing I can ignore?

This is normal processing.
