The following shows two instructions that add a 64-bit integer contained in R0 and R1 to
another 64-bit integer contained in R2 and R3, and place the result in R0 and R1.
64-bit addition:
Multiword values do not have to use consecutive registers. The following shows
instructions that subtract a 96-bit integer contained in R1, R2, and R3 from another
contained in R4, R5, and R6. The example stores the result in R4, R5, and R6.
96-bit subtraction:
The following shows the RSBS instruction used to perform a 1's complement of a single
register.
Logical AND, OR, Exclusive OR, and Bit Clear.
