I'll disagree with that.  An interrupt condition is *never* recognized
"during generation of [an] address."  An addressing exception or a
protection exception may be recognized subsequently when that
address is used to access storage.  And that is unrelated to whether
a carry out of the high-order bit position occurred.

Address generation and storage access are two different topics.  They
should be discussed separately.

Should I submit an RCF?
