Flat Assembler

Flat Assembler is a powerful tool designed for developers seeking to minimize the size of their compiled machine code through multiple optimization passes. It supports a wide range of processors from 8086 to 80486/Pentium, including modern instruction sets like MMX, SSE, SSE2, SSE3, and 3DNow! extensions. This makes it ideal for performance-critical applications where every byte counts, offering flexibility and precision in assembly programming without sacrificing compatibility.
