Branch operations are augmented slightly to be a little more like FP
Compares (FEQ, FNE etc.), by permitting the cumulation (and storage)
of multiple comparisons into a register (taken indirectly from the predicate
-table). As such, "ffirst" - fail-on-first - condition mode can be enabled.

See ffirst mode in the Predication Table section.
There are two registers for the comparison operation, therefore there
