FASM is a fast and efficient assembly language compiler that was created by Tomasz Grysztar. It was first released in 1999 and has since become a popular tool among low-level programmers and operating system developers.
The main features of FASM include:
- Self-hosting capability (it can compile itself)
- Support for multiple operating systems (Windows, Linux, DOS)
- Extremely fast compilation speed
- Small executable size
- Simple and clean syntax
FASM is particularly useful for:
- Writing operating system kernels
- Creating device drivers
- Developing low-level system utilities
- Learning assembly language programming
- Writing performance-critical code
Unlike many other assemblers, FASM doesn't require an external linker and can produce executable files directly. It also includes a powerful macro system that helps programmers write more maintainable code.
The program is free and open-source, making it accessible to anyone interested in assembly language programming or system development.
