Calculation of jmp distance of E9: distance = destination address-(current address + 5) (plus 5 is because the JMP command occupies a total of 5 words, actually the destination address minus the end address of the JMP command, that is, the current address + 5If the target address is f1e0b63eThe current address is 8093c6d8.Distance = f1e0b63e-8093c6d8-5 = 714cef61

Jump instructions are divided into three categories:First, unconditional jump: JMP;Second, according to the value of CX, ECX Register jump: JCXZ (CX is 0 jump), JECXZ (ECX for 0 jump);Three, according to the EFLAGS register flag bit jump, this too many.JMP Unconditional Transfer Instructions1, the direct short transfer within the paragraph 2, a direct near-transfer within the paragraph 3, within the paragraph near the transfer of 4, the direct transfe

In assembly, $ is used to obtain the address where $ is located. Therefore, JMP $ is an endless loop. Unless Interrupted, and the interrupted service program will be executed again. However, it should be noted that the returned address is still JMP $, rather than its The next statement. In JMP $ execution, the address of the

① JMP is not responsible for scheduling. It does not save any information, and it does not consider turning back. Skip this step.② Call, save EIP, and so on, so that the program can jump back. RET is the inverse process of call and the process of turning back. This is an inherent CPU command, so we do not need to save the information. Run the command directly.③ Privilege-level transfer within the same task, which is similar to ②, but you need to prepa

1. The difference between JMP is that one is intra-segment call and the other is inter-segment call. 2. The call is very different, because the call will have an impact on the stack:(1) The call's near call will not change the stack used, but the stack content has changed: the next command is pushed into the stack; if there is a parameter, the parameter is pushed into the stack.(2) The Remote Call of call changes the stack used. Because the stack use

Jmp selector: offset. The selector may indicate a segment descriptor or a gate descriptor. The cpu executes this command as follows: The above is my understanding of the jmp selector: offset execution process. In fact, the call selector: offset is similar, but the stack of cs and eip is added at the beginning and end, And the stack is output. (The arrow shown in the figure is a bit eye-catching. I can
