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

libudis86
|
|
---------
|
|
|
|
o Supports all x86 and x86-64 (AMD64) General purpose and
|
|
System instructions.
|
|
o Supported ISA extensions:
|
|
- MMX, FPU (x87), AMD 3DNow
|
|
- SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES,
|
|
- AMD-V, INTEL-VMX, SMX
|
|
o Instructions are defined in an XML document, with opcode
|
|
tables generated for performance.
|
|
o Supports output in both INTEL (NASM) as well as AT&T (GNU as) style
|
|
assembly language syntax.
|
|
o Supports a variety of input methods: Files, Memory Buffers, and
|
|
Function Callback hooks.
|
|
o Re-entrant, no dynamic memory allocation.
|
|
o Fully documented API

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

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