-TODO: split out (remove) bit 3 as separate so that twin predication can use the same encoding, and split thr table into 2 halves. The bit currently 3 becomes a separate (standalone) field (see [discussion])
+TODO: split out (remove) bit 3 as separate so that twin predication can use the same encoding, and split the table into 2 halves. The bit currently 3 becomes a separate (standalone) field (see [discussion]) that selects *both* src and dest predication as CR based or both as INT based. This saves one bit and makes things less complex.
