为了去掉指令地址中的指针标签。因为ARMv7 中的地址分为Thumb Mode 和 Normal Mode,对应的指令地址分别是2字节 和 4字节,arm64下指令地址都是4字节,(按照4字节对齐存储,一条指令必须从4的整数倍地址来取)所以指令地址的最后2 bits 肯定都是0,系统一般会在这后两位中插入一个指针标签,要去掉这个标签的值才是真正的指令地址。而x86_64中指令是可变长度的,所有的bits 都是有意义的。 这个宏的作用就是为了适配x86 和 arm平台的指令处理方式不同。 https://github.com/kstenerud/KSCrash/blob/master/Source/KSCrash/Recording/Tools/KSSymbolicator.c
Sorry, something went wrong.
