- Is the 64-bit name of the general-purpose base register or stack pointer.
- When "option<0>" is set to 0, is the 32-bit name of the general-purpose index register.
- When "option<0>" is set to 1, is the 64-bit name of the general-purpose index register.

Load Register Signed Word (register) calculates an address from a base register value and an offset register value, loads a word from memory, sign-extends it to form a 64-bit value, and writes it to a register. The offset register value can be shifted left by 0 or 2 bits. For information about memory accesses, see Load/Store addressing modes in the ARMv8-A Architecture Reference Manual.
