  • Fasm flat assembler (fasm) is a free multi-pass assembler written by Tomasz Grysztar.

Fasm is written in itself, has a small size and very high compilation speed, and has a rich and powerful macro syntax that allows you to automate many routine tasks.

It supports both object formats and executable file formats. This makes it possible to avoid using a linker in most cases. In other cases, you need to use third-party linkers,

as fasm does not come with one. In addition to the basic set of processor and coprocessor instructions, fasm supports SSE, SSE3, and 3DNow!
