我想hook sub_9d0这个函数查看输入和输出，hook代码如下，地址也是使用getClock绝对地址-相对地址+9d0 然后运行代码之后没有函数的任何输入和输出，请问是地址原因还是其实原因导致没有输入和输出呢。。。

hook_native_get_clock = '''
Java.perform(function () {
    send('native_hook')
    var nativePointer = Module.getExportByName('libcore.so','Java_com_yxcorp_gifshow_util_CPU_getClock');
    var basePointer = nativePointer.sub(0x1240);
    send('nativePointer:'+nativePointer);
    send('basePointer:'+basePointer);
    var sub_9D0 = basePointer.add(0x9D0);
    Interceptor.attach(sub_9D0,{
        onEnter:function(args){
            send('so hook success!');
            send('args[0]: '+ args[0]);
            send('args[1]: '+ args[1]);
        },
        onLeave:function(res){
            send('res: ' + res);
        }
    });
});
'''

对了 补充一点：是Interceptor.attach下之后就没有任何输入输出了，然后地址应该也是没问题的,因为我试了+1或者不+1不管从导入函数还是so基地取获得地址其实都一样，我想知道是否还有其他原因。。。函数也是调用了的，因为hook导出函getClock数没问题
