原理很容易理解，对于armv7 svc 0对应的00DF二进制 调用号是在r7寄存器中
armv8 svc 0对应的010000D4二进制 调用号是在x8寄存器中，只要在so文件中的.text段中找到相关的二进制字串就可以确定是否有 svc调用，再向前看就可以看出svc的调用号是多少。不同人不同写法，会导致分析调用号多少不一样
 
上图这个svc调用就比较难分析出来
而下图这个就比较简单。
实现原理就是遍历文件夹下的每个so文件读取elf信息找出.text代码范围，然后在这个里面找010000D4字串，然后向前去找X8的值 。
svc 调用可以越过沙箱，libc的hook,在一定程度上进行风控。
