OBJ2ASM is an object file disassembler for 16 and 32 bit x86 object files in Intel OMF, Microsoft COFF format, Linux ELF or Mac OS X Mach-O format. It can also disassemble and decompile Windows executables.
Hopper Disassembler is a reverse engineering tool for the Mac, that lets you disassemble, decompile and debug 32/64bits Intel Mac executables. Relyze Desktop is an interactive software reverse engineering tool that lets you disassemble, decompile and diff x86, 圆4, ARM32 and ARM64 software.

As such this wikibook will not consider IDA Pro specifically because the price tag is exclusionary. The downside to IDA Pro is that it costs $515 US for the standard single-user edition. Commercial Windows Disassemblers IDA Pro is a professional disassembler that is expensive, extremely powerful, and has a whole slew of features. The site is currently in beta release but will hopefully only get better with time. You can use "Live View" to see how code is disassembled in real time, one byte at a time, or upload a file. Online Disassemblers ODA is a free, web-based disassembler for a wide variety of architectures. Each disassembler will have different features, so it is up to you as the reader to determine which tools you prefer to use. Notice that there are professional disassemblers (which cost money for a license) and there are freeware/shareware disassemblers. Here we are going to list some commonly available disassembler tools. We will typically not use HLA syntax for code examples, but that may change in the future. Examples in this book will use Intel and AT&T syntax interchangeably. Many disassemblers have the option to output assembly language instructions in Intel, AT&T, or (occasionally) HLA syntax. Of course, disassembly has its own problems and pitfalls, and they are covered later in this chapter. Since most assembly languages have a one-to-one correspondence with underlying machine instructions, the process of disassembly is relatively straight-forward, and a basic disassembler can often be implemented simply by reading in bytes, and performing a table lookup.
Where an assembler converts code written in an assembly language into binary machine code, a disassembler reverses the process and attempts to recreate the assembly code from the binary machine code. In essence, a disassembler is the exact opposite of an assembler.
