LDRSW (literal) Load register signed word (literal) This instruction calculates an address from the PC value and an immediate offset, loads a word from memory, and writes it to a register. For information about addressing modes, see Load/Store addressing modes. 1 0 0 1 1 0 0 0 LDRSW <Xt>, <label> let t : integer{} = UInt(Rt); let nontemporal : boolean = FALSE; let tagchecked : boolean = FALSE; let offset : bits(64) = SignExtend{}(imm19::'00'); <Xt> Is the 64-bit name of the general-purpose register to be loaded, encoded in the "Rt" field. <label> Is the program label from which the data is to be loaded. Its offset from the address of this instruction, in the range +/-1MB, is encoded as "imm19" times 4. let address : bits(64) = PC64() + offset; let privileged : boolean = PSTATE.EL != EL0; let accdesc : AccessDescriptor = CreateAccDescGPR(MemOp_LOAD, nontemporal, privileged, tagchecked, t); let data : bits(32) = Mem{32}(address, accdesc); X{64}(t) = SignExtend{64}(data); 2026-03-12 12:23:09 2025-09_rel_asl1
