13.12.1.7
The example below shows two instructions that add a 64-bit integer contained in R2 and R3 to another 64-bit integer con-
tained in R0 and R1, and place the result in R4 and R5.
13.12.1.8
Multiword values do not have to use consecutive registers. The example below shows instructions that subtract a 96-bit
integer contained in R9, R1, and R11 from another contained in R6, R2, and R8. The example stores the result in R6, R9,
and R2.
