2======

4Udis86 is a disassembler for the x86 and x86-64 class of instruction set
5architectures. It consists of a C library called libudis86 which
6provides a clean and simple interface to decode a stream of raw binary
7data, and to inspect the disassembled instructions in a structured
8manner.

21  o Supports all x86 and x86-64 (AMD64) General purpose and
22    System instructions.
23  o Supported ISA extensions:
24    - MMX, FPU (x87), AMD 3DNow
25    - SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES,
26    - AMD-V, INTEL-VMX, SMX
27  o Instructions are defined in an XML document, with opcode
28    tables generated for performance.
29  o Supports output in both INTEL (NASM) as well as AT&T (GNU as) style
30    assembly language syntax.
31  o Supports a variety of input methods: Files, Memory Buffers, and
32    Function Callback hooks.
33  o Re-entrant, no dynamic memory allocation.
34  o Fully documented API

71Documentation
72-------------
73
74The libudis86 api is fully documented. The package distribution contains
75a Texinfo file which can be installed by invoking "make install-info".
76You can also find an online html version of the documentation available
77at http://udis86.sourceforge.net/.

80Autotools Build
81---------------
82
83You need autotools if building from sources cloned form version control
84system, or if you need to regenerate the build system. The wrapper
85script 'autogen.sh' is provided that'll generate the build system.
