option exists to include or exclude the failing element.
* Predicate-result: a strategic mode that effectively turns all and any
operations into a type of `cmp`. An `Rc=1 BO test` is performed and if
- failing the result is **not** written to the regfile. The `Rc=1`
- Vector of co-results **is** always written (subject to predication).
+ failing that element result is **not** written to the regfile. The `Rc=1`
+ Vector of co-results **is** always written (subject to usual predication).
Termed "predicate-result" because the combination of producing then
testing a result is as if the test was in a follow-up predicated
copy/mv operation, it reduces regfile pressure and instruction count.
and restoring of LR and SVLR may be deferred until the final decision
as to whether to branch. In this way `sv.bclrl` does not corrupt `LR`.
+Vectorised Branch-Conditional due to its side-effects (e.g. reducing CTR
+or truncating VL) has practical uses even if the Branch is deliberately
+set to the next instruction (CIA+8). For example it may be used to reduce
+CTR by the number of bits set in a GPR, if that GPR is given as the predicate
+mask `sv.bc/pm=r3`.
