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 87" | udcli -32 -x 0000000000000000 656789877665 mov [gs:bx+0x6576], eax 0000000000000000 54 push esp 0000000000000000 56 push esi 0000000000000000 7889 js 0x93 0000000000000000 0900 or [eax], eax ---------------------------------------------------------------------- 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. AUTHOR ------ Udis86 is written and maintained by Vivek Thampi ([email protected]).
