fasm-mode

fasm-mode is a major mode for editing FASM x86 assembly programs. It includes syntax highlighting, automatic indentation, and imenu integration. Unlike Emacs' generic asm-mode, it understands FASM-specific syntax. Requires Emacs 24.3 or higher.

The keyword lists are up to date as of FASM 1.73.32.
