LDRSW (literal) Load Register Signed Word (literal) Load Register Signed Word (literal) 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 memory accesses, see Load/Store addressing modes. If PSTATE.DIT is 1, the timing of this instruction is insensitive to the value of the data being loaded or stored. 1 0 0 1 1 0 0 0 LDRSW <Xt>, <label> integer t = UInt(Rt); MemOp memop = MemOp_LOAD; boolean signed = FALSE; boolean nontemporal = FALSE; integer size; bits(64) offset; case opc of when '00' size = 4; when '01' size = 8; when '10' size = 4; signed = TRUE; when '11' memop = MemOp_PREFETCH; offset = SignExtend(imm19:'00', 64); boolean tagchecked = FALSE; <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. bits(64) address = PC[] + offset; bits(size*8) data; boolean privileged = PSTATE.EL != EL0; AccessDescriptor accdesc = CreateAccDescGPR(memop, nontemporal, privileged, tagchecked); case memop of when MemOp_LOAD data = Mem[address, size, accdesc]; if signed then X[t, 64] = SignExtend(data, 64); else X[t, size*8] = data; when MemOp_PREFETCH Prefetch(address, t<4:0>);
