12 <h2>Disassembler Library for x86 and x86-64</h2>
16 <p>udis86 is an easy-to-use minimalistic disassembler
17 library (<i>libudis86</i>) for the x86 and x86-64 class
18 of instruction set architectures. The primary intent of
19 the design and development of udis86 is to aid software
20 development projects that entail binary code analysis.</p>
