GNU Assembler (GAS)

GNU Assembler (GAS) is a tool used in computer programming that translates assembly language code, which is a low-level language close to machine code, into binary code that a computer can understand and execute. It is part of the GNU Compiler Collection and supports various computer architectures. Programmers use GAS to write performance-critical code or to interface directly with hardware, making it essential for system programming, embedded systems, and operating systems development. Its flexibility and compatibility make it popular among developers working with open-source projects.
