The principle of data-dependent fail-first is that if a Condition Test
fails then VL (Vector Length) is truncated at that point. In the case
of Arithmetic SVP64 Operations the Condition Register Field generated from
-Rc=1 is used, however with CR-based operations that CR result is provided
+Rc=1 is used as the basis for the truncation decision,
+however with CR-based operations that CR result is provided
by the operation itself.
