FASM: Difference between revisions

The flat assembler (FASM) is a fast and efficient self-assembling 80x86x86 assembler for DOS, Windows and Linux*nix (BSD etc.) operating systems. Currently it supports all 8086-80486x86/Pentiumx64 instructions with MMX, SSE, SSE2, SSE3 and 3DNow!, extensionsSSE andup x86-64to (bothSSE4, AMD64AVX, AVX2 and EM64T)XOP instructionsextensions, can produce output in binary, MZ, PE, COFF or ELF format. It includes thea powerful but easy to use macroinstructionmacro supportlanguage and doescompiles in multiple passes to optimize the instruction codes for size. The flat assembler is self-compilable and the full source code is included.
