As can be seen from the table, the grammar of at-and-T is more obscure, because [Base+index*scale+disp] can see its meaning at a glance, and disp (Base,index,scale) is unlikely to do so.This approach is often used to access a field within a particular element of the data structure array, where base is the starting address of the array, and scale is the s

When reading the Linux kernel source code or performing performance optimizations on the codes, there is often a need to embed a piece of assembler code in the C language, which is called inline assembly in CS terminology.

Becoming a Senior Programmer proficient in Linux programming has always been the goal of many friends. According to statistics from chinacache, the monthly salary of Linux programmers in Beijing is 1.8 times that of Windows programmers, 2.6 times that of Java programmers, and 2.9 times that of Windows programmers. At the same time, the data shows that with the increase of work experience, the income gap bet

I. Advantages and Disadvantages of assembly language:
Since Linux is written in C, C naturally becomes the standard programming language of Linux. Most people ignore the compilation, and it is very difficult to find information on the Internet.
