8086 disassembler download 8 3
Major Linux distributions take care of SDCC installation packages themselves and you will find SDCC in their repositories. Unfortunately SDCC packages included in Linux disributions are often outdated. In this case users are encouraged to compile the latest official SDCC release or a recent snapshot build by themselves or download the pre-compiled binaries from Sourceforge download page.
If you're just looking to use a disassembler, then objdump is one choice. The disassembler that comes with the nasm assembler is ndisasm. You can also run "debug.exe" in DOS Box on Linux, provided you get a hold of a copy of the program. It also does disassembly, as well as controlled execution; i.e. simulation of the CPU, itself - which is also important, even when doing disassembly, for reasons I'm about to describe.
This gets to the other sense of your query: "I want to make a disassembler". The source for ndisasm is available, and it handles many of the descendants of 8086, not just 8086, itself (which seriously clutters it, if all you want is an 8086 or even 80386 disassembler), but it is not self-contained and has a heavy dependency on the rest of the distribution.
Its main talking point is that it uses octal digits for the opcodes - which better fits the 80x86 - as I pointed out on the USENET in 1995 in comp.lang.asm ... and (in fact) nasm's creation was a direct response to that. So, it's potentially more transparent and you may want to keep the source handy as a check and comparison, if you're making your own disassembler.
And then you've just disassembled a disassembler that also happens to do CPU emulation, like Fake86 does - but only for the 8086. You'll have to make the absolute addresses relative (using the original relocation table as a guide), to make is re-assemblable. Once you do that, you can work on the source. The opcode table is in clear view (if you display it as text) - both when seen in the packed and unpacked versions of debug.exe.
There's also DosDebug up on GitHub. It handles everything up to "80586" (or Pentium") and "80686": it flags a generation "6" for some instructions.; e.g. the conditional "cmov" operations are handled by it, as well as their "fcmov" floating point versions. DosDebug is in 8086 assembly and is best-suited to compile with jwasm. You might be able to run nasm on it, I don't know. I never tried.
I might port the DAS disassembler to the x86, since items (a)-(f) are already incorporated into DAS's design. I've only ever ported it to the 8051, 6800, 6809 and 8080/8085 (and Z80) up to now; but the transition from 8085 to 8086 is relatively small. To that end, I might hack something out of Fake86. That's mostly abandonware, now, since the author replaced it by XTulator, as Fake86 was written when the programmer was relatively new to C. You might also be able to hack something directly out of DosDebug's opcode tables (their "instr.*" files).
There are two examples given of elf-executables with their disassembly and reassembly. It was originally designed to be able to modify a booting system, consisting of code, interpreted code, data and graphic characters, with such niceties as a transition from real to protected mode. (It succeeded.) The examples demonstrate also the extraction of text from the executables, that is subsequently used for labels. The debian package is intended for Intel Pentium, but plug ins are available for Dec Alpha, 6809, 8086 etc.
Hackman Suite is a multi-module all purpose debugging tool. It includes a hex editor, a disassembler, a template editor, a hex calculator and other everyday useful tools to assist programmers and code testers with the most common tasks.
The DisassemblerHackman Disassembler 9.0 is an ultra fast multi processor disassembler, capable of disassembling code at a rate of 250 Kb/sec (PIII/900 MHz). The opcodes cover all x86 Intel and AMD architecture, starting at 8086 and ending at 3DNow! and Pentium 4 specific instructions. With Hackman Disassembler you have a multi-disassembling suite integrated into one program with a handy interface. Opcode sets are available for Intel 8086/80286/80386/80486 (*), Intel Pentium/Pro/MMX/II/III/P4 (*), AMD 3DNow! (*), 1802 (*), 6502/6510/8500/8502, 65816, 65C02/65SC02, 65CE02, Motorola 6800/6802/6808 (*), Motorola 6801/6803 (*), Motorola 6805/146805 (*), Hitachi 6809/6309, 8085, Zilog Z80, Gameboy CPU, Java Bytecode.

and parameters are passed to these calls on the stack.The comments instruct us to assemble into an object formatof "win32" (not "coff"!) then link with the linker ld.Of course you can use any linker you want, but ld comeswith gcc and you can download a whole Win32 portof gcc for free. We pass thestarting address to the linker, and specify the static librarylibkernel32.a to link with. This static libraryis part of the Win32 gcc distribution, and itcontains the right calls into the system DLLs. 2ff7e9595c
