Assembly language is always indispensable in the source code of any operating system. Therefore, assembly language is an essential basic knowledge for learning the operating system. However, at present, most of the teaching in China is conducted on the Windows platform, therefore, most readers are familiar with Intel's Assembly syntax, but att's assembly is used in Linux kernel code. This section compares the two types of assembly, allowing readers who are familiar with Intel assembly syntax to

Using Jquery to operate HTML elements is very convenient and flexible to search. In fact, CSS can also be used for searching and filtering flexibly and conveniently. Some of the following are some of the useful operations, which will be added later.

Looking at the "Programmer's ego" Recently, I saw the GCC inline assembly, the static link chapter of the sample program is more interesting, so ready to learn the att syntax of the GCC inline assembly. I used to learn the computer principles of the Assembly, now basically returned to the teacher, or review it. First of all, let's introduce the difference between the att syntax and the Intel ASM syntax (and

Various selectors for CSSFirst, the basic selector1. * Universal element Selector, matches any element2. E Tag Selector, matching all elements using e tag3.. info class selector that matches all elements of the class attribute that contain info4. #footer the ID selector to match all elements of the id attribute equal to footerTwo, multi-element combination Selector5. E,f multi-element selector, matching all e elements or F elements, separated by commas between E and F6. E F descendant element se

When designing a website, we sometimes need to make different styles Based on the properties of the page elements. For example, different link icons are displayed for different link types. CSS selector is a very useful technique. Through them, we can easily implement some effects. Today, we will introduce the CSS attribute selector by creating a personalized link style. Let's take a look at the demo: As we can see in, we define different styles for each link: When the href attribute value of l

References: Linux kernel full analysis, new assembly language programming, and Linux C Programming one-stop learning Recently, a key part of the C language algorithm needs to be implemented in assembly language. In Linux, att assembly is basically used for Embedded Assembly. For example

In the Linux kernel, many of the applications that come into contact with the underlying hardware use the assembly language. However, Linux uses not only an assembly language, but also Intel's assembly language, we still use att's assembly language, so we can say that these two are a foundation. Intel's compilation is believed to have been learned by many people studying computers, but att's compilation is not necessarily true, I think their thinking is the same, but the syntax is different, the

I. IntroductionThe code written in assembly language in Linux has two different forms. 1) complete assembly code It means that the entire program is all written in assembly language. Despite the complete compilation code, the compilation tools on the Linux platform also absorb the advantages of the C language, so that programmers can use the # include, # ifdef, and other pre-processing commands, and can simplify the Code through macro definition. 2) Embedded Assembly Code It refers to the assemb
