Can programs written in assembly be used on Linux?

Programs written in assembly can be used in Linux, but they need to follow the following points: 1. Follow the ABI standard of the Linux system to ensure that the program is compatible with the interface of the operating system; 2. You need to use Linux system calls to access operations System functions require the use of specific instructions to trigger system calls; 3. Need to understand the function calling specifications of the C language to correctly use the library functions provided by the Linux operating system to complete some advanced functions; 4. Need to understand the system of the target computer structures and instruction sets, and requires manual management of resources such as registers and memory.

Assembly language is a low-level language that directly operates the computer's hardware. Different computer architectures have different instruction sets and assembly languages, so assembly programs written may not be compatible on different computers.

On the Linux operating system, assembly language programs can run, but you need to pay attention to the following points:

The assembler must follow the ABI (Application Binary Interface) standard of the Linux system to ensure that the program is compatible with Operating system interfaces are compatible. ABI defines specifications for function calls, register usage, parameter passing, etc. to ensure that different programs can run on the same operating system.

The assembler needs to use Linux system calls (System Call) to access operating system functions, such as file operations, process management, etc. In Linux, system calls are implemented through soft interrupts (software interrupts), and the assembler needs to use specific instructions to trigger the system call.

The assembler needs to use the library functions provided by the Linux operating system (such as the C standard library) to complete some advanced functions, such as memory allocation, string operations, etc. The interfaces of these library functions are written in C language, so the assembler needs to understand the function calling specifications of C language to use these library functions correctly.

When writing an assembly program, you need to understand the architecture and instruction set of the target computer, and you need to manually manage resources such as registers and memory. Therefore, writing assembly programs is relatively more complicated and requires a certain understanding of the underlying principles of the computer.

Summary

Assembler can run on the Linux operating system, but it needs to follow the ABI standard of the Linux system, use system calls and library functions, and needs to have a certain understanding of the underlying principles of the computer . For general application development, it is more convenient and efficient to use high-level languages ​​(such as C, C, Python, etc.), while assembly language is more suitable for specific scenarios with extremely high performance requirements, such as drivers, embedded systems, etc.
