我单步到@1时 奇怪的事情发生了 下一步执行到了@2 而不是@3

而我如果不要mov lr,pc 这句 或者在mov lr, pc 后面再加一些指令 则单步到@1后直接跳到@3 请问这是为什么-I single-step into @ 1:00 strange things have taken place in the next step to implement the @ 2 and not 3 and I @ If not mov lr, pc or in this mov lr, pc followed by a number of commands are single-step to one after the @ skip @ 3 I would like to ask why this is
