NASM是一种80x86和x86-64汇编程序，旨在实现可移植性和模块化。它支持一系列对象文件格式，包括Linux和BSD"a.out"、ELF、Mach-O、16位和32位".obj"（OMF）格式、COFF（包括其Win32和Win64变体）。它还可以输出纯二进制文件、Intel hex和Motorola S-Record格式。它的语法设计简单易懂，与“英特尔软件开发人员手册”中的语法相似，但复杂度最低。它支持所有当前已知的x86体系结构扩展，并且对宏有很强的支持。
The Netwide Assembler, NASM, is an 80x86 and x86-64 assembler
designed for portability and modularity. It supports a range of
object file formats, including Linux and *BSD `a.out', ELF, Mach-O,
16-bit and 32-bit `.obj' (OMF) format, COFF (including its Win32 and
Win64 variants.) It can also output plain binary files, Intel hex
and Motorola S-Record formats. Its syntax is designed to be simple
and easy to understand, similar to the syntax in the Intel Software
Developer Manual with minimal complexity. It supports all currently
known x86 architectural extensions, and has strong support for
macros. (2020-09-03, Asm, 1011KB, 下载0次)
