STUR

Store Register (unscaled).

Syntax

STUR Wt, [Xn|SP{, #simm}] ; 32-bit general registers

STUR Xt, [Xn|SP{, #simm}] ; 64-bit general registers

Where:

Wt

Is the 32-bit name of the general-purpose register to be transferred.

Xt

Is the 64-bit name of the general-purpose register to be transferred.

Xn|SP

Is the 64-bit name of the general-purpose base register or stack pointer.

simm

Is the optional signed immediate byte offset, in the range -256 to 255, defaulting to 0.

Usage

Store Register (unscaled) calculates an address from a base register value and an immediate offset, and stores a 32-bit word or a 64-bit doubleword to the calculated address, from a register. For information about memory accesses, see Load/Store addressing modes in the ARMv8-A Architecture Reference Manual.
