Syntax
LDRSW
Xt, [Xn|SP], #simm ; Post-index general registers
LDRSW

LDRSW
Xt, [Xn|SP{, #pimm}] ; Unsigned offset general registers
Where:
simm-
Is the signed immediate byte offset, in the range -256 to 255.
pimm-
Is the optional positive immediate byte offset, a multiple of 4 in the range 0 to 16380, defaulting to 0.
Xt-

Usage
Load Register Signed Word (immediate) calculates an address from a base register value and an immediate offset, loads a word from memory, sign-extends it, and writes it to a register. For information about memory accesses, see Load/Store addressing modes in the ARMv8-A Architecture Reference Manual.
