SDIV Signed divide This instruction divides a signed integer register value by another signed integer register value, and writes the result to the destination register. The condition flags are not affected. 0 0 1 1 0 1 0 1 1 0 0 0 0 0 1 1 0 SDIV <Wd>, <Wn>, <Wm> 1 SDIV <Xd>, <Xn>, <Xm> constant integer d = UInt(Rd); constant integer n = UInt(Rn); constant integer m = UInt(Rm); constant integer datasize = 32 << UInt(sf); <Wd> Is the 32-bit name of the general-purpose destination register, encoded in the "Rd" field. <Wn> Is the 32-bit name of the first general-purpose source register, encoded in the "Rn" field. <Wm> Is the 32-bit name of the second general-purpose source register, encoded in the "Rm" field. <Xd> Is the 64-bit name of the general-purpose destination register, encoded in the "Rd" field. <Xn> Is the 64-bit name of the first general-purpose source register, encoded in the "Rn" field. <Xm> Is the 64-bit name of the second general-purpose source register, encoded in the "Rm" field. constant bits(datasize) operand1 = X[n, datasize]; constant bits(datasize) operand2 = X[m, datasize]; integer result; if IsZero(operand2) then result = 0; else result = RoundTowardsZero(Real(SInt(operand1)) / Real(SInt(operand2))); X[d, datasize] = result<datasize-1:0>;
