golang underlying implementation language

Golang is a programming language that focuses on efficiency and reliability and is becoming increasingly popular in modern development environments. The underlying implementation language of Golang uses C language. This article will discuss the implementation of Golang's underlying language from the following four aspects: the characteristics of Golang language, the relationship between Golang and C language, the compilation process of Golang language, and the underlying implementation of Golang.

Features of Golang language

Golang language is a programming language launched by Google in 2007. Its design concept is to give full play to the performance of modern computer hardware and improve programming efficiency through other methods. The characteristics of Golang language are mainly reflected in the following aspects:

1. The syntax is simple and easy to read: Golang language draws on the syntax of C language and C language, and optimizes it based on this. Semicolons are used to separate statements in Golang language, but the semicolons can be omitted during use.
2. Memory management optimization: The memory management of the Golang language is implemented through the garbage collector. There is no need to manually allocate and release memory during the programming process, thus reducing the programmer's workload.
3. Concurrency processing: The concurrent processing capability of Golang language is very powerful. It provides two language elements, goroutine and channel, making multi-threaded concurrent operations very simple.
4. Code is clear and easy to maintain: The structured programming method of Golang language makes the code clear and easy to understand, and can be easily maintained.

The relationship between Golang and C language

Golang has many similarities with C language, such as syntax and some data types. This is because the designers of Golang, Rob Pike, Ken Thompson and Robert Griesemer, are all senior programmers of C language and they are very familiar with C language. In the design of the Golang language, many advantages of the C language were borrowed, and new language features were also added, such as coroutines and garbage collection.

Although Golang has many similarities with the C language, there are also some key differences. Golang's memory management is implemented through the garbage collector, while C language requires manual control of memory allocation and release. Golang introduces the concept of coroutines, making concurrent programming simpler and more efficient than C language.

Compilation process of Golang language

The compilation process of Golang language is relatively simple. Golang code needs to be compiled into machine code by a compiler and then run on the operating system. Unlike other programming languages, the Golang compiler supports cross-compilation and can compile Golang code into machine code under various operating systems and platforms. This means that programmers can use Golang language to write applications with cross-platform features, making application development and deployment more flexible and convenient.

The underlying implementation of Golang

The underlying implementation of Golang uses C language. The Golang compiler is based on LLVM technology, and the underlying instructions are generated by LLVM. The execution flow of the Golang program is as follows:

1. Code compilation: The Golang code first needs to be compiled into intermediate code, which is the Go assembly file.
2. Intermediate code conversion: The intermediate code is converted into Go object files.
3. Linking: Go object files are linked into an executable file.
4. Run: The executable file is loaded into memory and executed.

In short, the underlying implementation of Golang uses C language, and the Golang code needs to go through multiple stages of conversion and linking during the compilation process before it can finally become an executable file and be executed.

Conclusion

Golang language is a programming language that focuses on efficiency and reliability. Its underlying implementation uses C language and draws on many syntax and features of C language. Golang's compilation process is relatively simple and supports cross-compilation, making Golang programs cross-platform. The Golang compiler uses LLVM technology, and the underlying instructions are generated by LLVM. Ultimately, Golang programs need to be compiled, linked, and executed.
