Upload full logcat?

logcat 不太方便发出来,strexeq r0, r0, [ip] 还有别的写法吗,
我这s23上 hook 了一个静态函数,但是 s21 没问题,都是 android 13,多跑了几次就报 ILL_ILLOPC,看上边的日志是不是这行报错的?

也就是说,第一次跑没问题?那我怀疑不是 strexeq 的问题,是这里的内存被不知道谁改掉了。你确定崩溃的时候这里还是 strexeq 指令?我倾向于野指针破坏了这里的内存

我不确定,那段汇编我基本上是写下来就没管过,应该有三年了,调用约定全忘光了……
刚刚翻了一下 art 源码,R4 寄存器在 art 上在调用 jni 方法时被用了存储 “locking register” 和 “hidden argument” ,可能需要测试执行 synchonized 的 jni 方法时触发 SIGQUIT 信号产生 ANR dump 时会不会有问题
我其实觉得 r4 能用就没道理 r0 不能用,而且执行几次后才崩溃不像典型的非法指令,我怀疑可能是指令缓存之类的有问题
公司有一台 Pixel 4 XL 刷了 android 13,有空我去试一下

能提供一下 hook 的是哪个方法吗,我这里没有复现出来
