Python decodeBitMasks Examples

Example #1

def mov_bmi(binary, N):
    inst = 'MOV '
    rdKey = utilFunc.getRegKeyByStringKey(binary[27:32])
    if (N == 32):
        r = 'w'
    else:
        r = 'x'
    inst += r + str(rdKey)

    immr = binary[10:16]
    imms = binary[16:22]
    immN = binary[9]

    imm, temp = utilFunc.decodeBitMasks(immN, imms, immr, N)
    inst += ', #' + utilFunc.binaryToHexStr(imm)
    result = utilFunc.logical_or('0' * N, imm).zfill(const.REG_SIZE)
    utilFunc.finalize(rdKey, result, inst, '1')
