Udis86
======
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.
LICENSE
-------
Udis86 is distributed under the terms of the 2-clause "Simplified BSD
License". A copy of the license is included with the source in LICENSE.
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
-- EXAMPLE -----------------------------------------------------------
ud_t u;
ud_init(&u);
ud_set_input_file(&u, stdin);
ud_set_mode(&u, 64);
ud_set_syntax(&u, UD_SYN_INTEL);
while (ud_disassemble(&u)) {
printf("\t%s\n", ud_insn_asm(&ud_obj));
}
----------------------------------------------------------------------
udcli
-----
udcli is a small command-line tool for your quick disassembly needs.
-- EXAMPLE -----------------------------------------------------------
$ echo "65 67 89 87 76 65 54 56 78 89 09 00 90" | udcli -32 -x
0000000080000800 656789877665 mov [gs:bx+0x6576], eax
0000000080000806 54 push esp
0000000080000807 56 push esi
0000000080000808 7889 js 0x80000793
000000008000080a 0900 or [eax], eax
000000008000080c 90 nop
----------------------------------------------------------------------
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.

udis86 Version 1.7.2
Disassembler library written in C, by vivek.mt@gmail.com
2-clause BSD license (see LICENSE)
Documentation: http://udis86.sourceforge.net/
Checked out from https://github.com/vmt/udis86
commit b24baf1e32bdd9ea12cc9f6dc4882b6ba04de0d7
Date: Thu Nov 14 12:28:33 2013 -0800
Various unnecessary parts, like unittests, bootstrapping scripts and a
command-line utility have been stripped out. This is just the bare
library.
In a normal build, libudis86/itab.h libudis86/itab.c are actually
generated from XML tables and a python script, but I've simply checked
in the generated results to keep things smaller and avoid that
bootstrapping step.
I did something similar with config.h, which would normally be
generated through automake/configure. This is probably less OK, but
will do for now.
