What is GCC (GNU Compiler Collection)?

GCC is a compiler for GNU, which is considered a standard for Operating Systems derived from proprietary Operating Systems such as UNIX, Open Source, or Mac OS X.

What is GCC (GNU Compiler Collection)?

GCC History and Features

The first version of it was made in 1987. This was an important advance, the first ANSI C compiler optimization laptop to be released as free software.

Since then, it has become one of the most important tools in the development of free software.

A large compiler review came with the 2.0 series that added the ability to compile C++ in 1992. An experimental compiler branch (SLGE) was created in 1997 to improve C++ optimization and support.

After this work, egcs was considered the new major development line, and these features were made widely available in 2001 in version 3.0.

Over time, it has expanded to support many languages ​​such as Fortran, Ada, Java, and Objective-C.

Its development is guided by the Steering Committee, a group of representatives of the user communities in the industry, research, and academia.

It stands for GNU Compiler Collection. These abbreviations used to be for the GNU C Compiler.


As the name suggests, it is a collection of compilers and supports C, C++, Objective C, Chill, Fortran, Ada, and Java languages.

It is part of the GNU project, which aims to develop the compiler used in GNU systems, including the GNU/Linux variant.

GCC development uses an open development environment and many other tools to encourage the use of the global class compiler optimizer, attract many development teams, make GCC and GNU systems work in different architectures and different environments, expand and develop GCC features, and it supports more.

It requires applications known as Binutils to perform tasks such as copying, translating, or creating lists, linking them, or defining or resizing object files to remove unnecessary symbols.

The compiler is distributed under the GPL (General Public License), which makes it freely available. You may make copies and export or sell as long as the Source Code is included and the license is protected.

There are versions for almost all operating systems. It comes with most GNU/Linux distributions. The DOS version of this compiler is DJGPP.

Hundreds of volunteers from all over the world are involved in the development of this compiler.


The GCC external interface is usually standard for the UNIX system.

Users call a controller program called GCC, which interprets the given arguments, decides which compiler to use for each file, runs the compiler with the resulting code, and then runs the connector to produce a complete program.

Each compiler is a separate program that takes the Source Code as input and generates Assembly code.

They all have a common internal structure, a Front End that processes the language and produces a syntax tree, and a common internal structure that converts these trees into the RTL Language then performs various optimizations and produces the installer using architecture-specific pattern recognition.

This is based on the algorithm of Jack Davidson and Chris Fraser.

Although most of the front end of the island is written on the Island, almost all of the GCC is written in C.
