There are many methods to analyze the crash log in Mac OS. Here we do not want to explain how to analyze the crash log, mainly to show the usage of Hopper. The powerful Ida may already be known, but its Mac OS version has brought us back to the DOS era. Fortunately, Mac OS has a small alternative: Hopper, which basically meets the need for disassembly at work, including pseudoCodeAnd control flow graph, which supports arm instruction sets and optimize

When a little accident, or do a more embarrassing thing, you can say "Oops", translated into Chinese words is called "Ah Yo." "Oh, sorry, I'm sorry, I didn't mean to break your cup." Look, that's what oops means.What is oops in the development of Linux kernels? In fact, it does not have t

What is block function blocks in the previous article? Describes the disassembly implementation of block function blocks defined in a function, and I have repeatedly pointed out that __block variables and block function blocks are both stack-based and not entirely suitable for use outside the scope of defining them, including asynchronous callbacks.

This kind of problem is often encountered during the examination or question preparation. The teacher who gives the question is willing to drill the tips on this point, that is, the combined operation of the auto-increment and auto-increment operations. I personally think that, it doesn't make much sense to take such a question, because different compilers have different results, and this is misleading, without the essence of language learning, but we still have to face it ...... Sad. The follow

and other hardware. How to drive these hardware is done by software.
Programming is done on the basis of the operating system through the operation of the Code and then compiled by the compiler to execute.
In Linux we have a disassembly to test how C code is converted into assembly code.
We do this on the lab floor, the C code is a simple three function (a main function and two called functions):
Disassembly
"]" between the value of the left operand, here is put Eax+2*eax into eax.and the sixth Line Assembly is actually the meaning of the value pointed to by the pointer, that is, Intel compiled:MOV Eax,[edx+4*eax]It means taking the value of the memory address edx+4*eax and putting it in the eax. As for what this value is, we do not know, so the book also only wrote a m[...].If you turn the mov of the last instruction into a lea:Lea Eax,[edx+4*eax]It means to put the value of Edx+4*eax in the EAX.W
In response to the phrase "it is more difficult to win the world to keep the world", server maintenance is like "keep the world "! The network is paralyzed by a slight random gain. Maintaining servers requires a thorough understanding of the hardware, operating systems, and application software systems of the servers. It is also a system engineering, hardware System maintenance is the most basic and important part of server maintenance and an endless task.
