3.5.5 Shift Instructions
Shift 32-bit Integer
Description:
Shifts a 32-bit integer left or right. The shift count is a two’s complement
integer stored in an ARM register; the count is positive for left shifts and
negative for right shifts. This instruction may also be used to copy a 32-bit
integer from one register to another by using a shift value of 0.

Shift 64-bit Integer
Definition:
Shifts a 64-bit integer left or right. The shift count is a two’s complement
integer stored in an ARM register; the count is positive for left shifts and
negative for right shifts. This instruction may also be used to copy a 64-bit
integer from one register to another using a shift value of 0.
