NASM (the Netwide Assembler) is a portable, cross-platform assembler for the x86 and x86-64 CPU architectures using Intel-like syntax. It supports many output formats and is licensed under the 2-clause BSD license.
Use cases
- assemble x86 assembly code
- write bootloaders or OS kernels in assembly
- compile assembly for x86-64 with Intel syntax
- generate object files in multiple formats like ELF or COFF
- learn x86 assembly programming
When to choose
- you need a mature, portable x86 assembler with Intel syntax
- you target multiple output formats and platforms
- you are writing low-level code such as bootloaders, kernels, or optimized routines
When to avoid
- you prefer AT&T syntax (consider GNU as)
- you need a high-level assembler with macros for other architectures like ARM
