请教大佬一个问题阿。我先用dcc生成jni工程，可以正常编译的。但是开启ollvm混淆的时候编译就报错 ld: error: duplicate symbol: .datadiv_decode 了。查看了对应报错的地方，两个函数名称不一样，参数也不一样，为什么报duplicate symbol阿。请问这种要怎么解决呢。

LOCAL_CFLAGS += -mllvm -sobf -mllvm -fla -mllvm -sub -mllvm -seed=B52822A68FC6C07D65A5044D75F09AEB

首先dcc已经替换了指令
-mllvm -sub指令替换
-mllvm -seed 加种子 这两个回导致指令重排，去掉这两个就可以
