Selector
Select all the child elements of the E element f
E+F
Adjacent selector
Select the F element that adheres to the E element
E~F
Brother Selector
Select e element all sibling element F
Here are a few things to note:
The child selector can only select the word element, not the grandchild, and the inclusion selector will select all eligible descendants, including the son, grandson, grandson ...
The adjacent selector selects only

are: in the kernel "pure" assembly code, GNU uses syntax different from the usual 386 assembly language, and in snippets of C programs, there are additional language components that instruct the assembler how to allocate the registers and how to combine the variables defined in the C program. These components make the assembly-language fragment embedded in the C program actually become a kind of intermediate language between the 386 assembly and C.

language in Linux has two different forms. The first is complete assembly code, which 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. The second is embedded assembly code, which refers to the assembly code snippe
language standards do not provide relevant provisions on Embedded Assembly Code, all the actually used C compilers have been expanded in this regard, of course, this includes GCC on the Linux platform.
Ii. Linux Assembly syntax format
The vast majority of Linux programmers have previously only been familiar with DOS/Windows assembly languages. These Assembly codes are Intel-style. However, in Unix and Linux systems, the ATT format is mostly used. T
I. att format Linux Assembly syntax format
In att Assembly format, Register names must be prefixed with '%'. In Intel assembly format, Register names do not need to be prefixed. For example:

Currently, many open-source C/C ++ Based on the x86 processor environment, and the assembler included in the objective-C/C ++ compiler uses the att format. Att assembly differs from other processors (such as arm and Blackfin) in x86 instruction sets. It is significantly different from Intel's custom Assembly format. The GCC assembler supports intel syntax. You can refer to my previous blog post to learn how
Differences between att assembly and Intel assembly
(1) In intel format, most uppercase letters are used, while in att format, lowercase letters are used.
(2) In att format, Register names must be prefixed with "%", but not intel format.
(3) In att's 386 assembly language, the order of the source and target operands of commands is the opposite of that in Intel's
