libdisassemble is a Python library that will disassemble X86.

A disassembler is a computer program which translates machine language into assembly language, performing the inverse operation to that of an assembler. A dissasembler differs from a decompiler, which targets a high level language rather than assembly language. Disassembly, the output of a disassembler, is often formatted for human-readability rather than suitability for input to an assembler, making it principly a reverse-engineering tool.

Assembly language source code generally permits the use of symbolic constants and programmer comments. These are usually removed from the final machine code by the assembler. If so, a disassembler operating on the machine code would produce disassembly lacking these constants and comments; the dissassembled output becomes more difficult for a human to interpret than the original annotated source code.

Some disassemblers can infer useful names and comments; however, interactive disassemblers are able to successfully disassemble more programs than fully-automated disassemblers because human insight applied to the disassembly process parallels human creativity in the code writing process.

There can never be a completely automated disassembly tool which always outputs correct source code because the disassembly process reduces to the impossible-to-solve halting problem.

The flat assembler is a fast and efficient self-assembling 80x86 assembler for DOS, Windows, and Linux operating systems. Currently, it supports all 8086-80486/Pentium instructions with MMX, SSE, SSE2, SSE3, and 3DNow! extensions.
It can produce output in binary, MZ, PE, COFF, or ELF format. Flat Assembler includes the powerful but easy-to-use macroinstruction support, and does multiple passes to optimize the instruction codes for size. The flat assembler is entirely written in assembly language.
Enhancements:
- 32-bit relocations are now allowed in PE64 output format.
- EIP-relative addressing was added.
- The PLT operator was added for the ELF output format.
- SSSE3 (Supplemental SSE3) instructions were added.
- Some Win64 headers and examples were provided in the Windows package.
- The SYSRETQ mnemonic was added, and RDMSRQ/WRMSRQ/SYSEXITQ mnemonics were added for the 64-bit variants of respective instructions.
- R8L-R15L (Intel-style) aliases were added for R8B-R15B registers. Support for the AMD SVM technology instructions was added. Numerous bugs were fixed.

This application is particularly useful for owners of digital DV video cameras and other people who use the Sony DV video format for high quality video production.

DV Assembler allows you to append multiple Sony DV files with nice looking transition effects for both audio and video. Multiple transition effects are supported, like cross-fade, zoom, blur and a flash effect.

I created DV Assembler because there are no user friendly video editing applications for Linux. Yes, Kino is promising, but its user interface is still a mess and development is slow.

DV Assembler only touches the head and tail parts of the original video files that are needed to create the transition effects. The rest of the video is left untouched, which means zero quality loss.

DV Assembler can also be used to generate video editing scripts that can be run without KDE and Kommander.

Rational PIC Assembler is an assembler for the mid-range microcontrollers from Microchip. The project uses Intel style mnemonics and target-first operand ordering. Designed to feel comfortable to PC assembly programmers.
This assembler generates code compatible with Microchips midline microcontrollers but is incompatible with their assembler. It should feel familiar to any PC assembly programmer. The instruction mnemonics and operand order are Intel style ( i.e. right, as opposed to wrong ).
Command Line Syntax
pic-asm [ -c ] [ -l filename ] [ -o filename ] input_file
-c -- console mode
an assembly source is accepted from stdin. binary code is
output on stdout. errors are output to stderr
-l filename -- specify listing file
-o filename -- specify object file
Input
The input is a sequence of line each of which contains one or more of the following fields
label instruction operands ; comment
The label and comment are optional. The operands required depend on the instruction.
The assembler is case sensitive, even for instructions.
Constants
Hex values can be specified with C-style 0x[:xdigit:]+. Binary values can be specified with 0b[01]+. Decimal values require no prefix as decimal is the default base.
Character constants are specified by enclosing a single character or escaped character within single quotes. String constants are specified by enclosing zero or more characters and escaped characters within double quotes. String constants generate one character constant for each character in the string. There is no trailing zero stored. For example:
db "Hello worldn", 0, a, b, r, n, t
Labels
A label is a sequence of alphanumeric characters ( including underbar ) that starts a line. Labels do not have colons. Labels local to the last nonlocal label can be defined by prefixing the name with a dot. For instance
; example from example-1.asm
foo call .1
.1 jmp .2
.2 jmp .1
bar call .1
.1 jmp .2
.2 jmp .1
In this example, the labels defined are foo, foo.1, foo.2, bar, bar.1, and bar.2. The first call branches to foo.1. The second call branches to bar.1. The labels local to foo can not be referenced before foo has been declared nor after bar has been declared.
Directives
Data can be declared. The declarator takes the place of the instruction and is followed by one or more expressions separated by commas. Each expression corresponds to one word in the output code regardless of the declarator type.
db - each operand is AND-ed with 0xff before being stored
dw - full 14 bit word definition
dt - each operand is AND-ed with 0xff and OR-ed with 0x3400 ( the return-with-value opcode ). This allows generation of case tables. You can add the accumulator ( w ) to the offset of the table. The processor will branch to the location in the table and return with an eight bit result
For instance:
db 1,2,3
dw 0x3fff, 0x3ff * 16 + 15, -1
dt 0b001, 0b010, 0b100
Equates are a named sequence of tokens. They can be defined with equ. For instance:
led_1 equ 0x100 | 1
led_2 equ 0x100 | 2
combo equ ( led_1 ) | ( led_2 )
The org position can be changed with org. For instance
org 0x10o
Enhancements:
- This release adds support for sophisticated macros, include files, conditional compilation, and compatibility with Microchip headers.

NASM is an 80x86 assembler designed for portability and modularity. The project supports a range of object file formats including Linux a.out and ELF, COFF, Microsoft 16-bit OBJ and Win32. It will also output plain binary files.
Its syntax is designed to be simple and easy to understand, similar to Intels but less complex. It supports Pentium, P6, MMX, 3DNow! and SSE opcodes, and has macro capability. It includes a disassembler as well.
The Netwide Assembler grew out of an idea on comp.lang.asm.x86 (or possibly alt.lang.asm - I forget which), which was essentially that there didnt seem to be a good free x86-series assembler around, and that maybe someone ought to write one.
- a86 is good, but not free, and in particular you dont get any 32-bit capability until you pay. Its DOS only, too.
- gas is free, and ports over DOS and Unix, but its not very good, since its designed to be a back end to gcc, which always feeds it correct code. So its error checking is minimal. Also, its syntax is horrible, from the point of view of anyone trying to actually write anything in it. Plus you cant write 16-bit code in it (properly).
- as86 is Minix- and Linux-specific, and (my version at least) doesnt seem to have much (or any) documentation.
- MASM isnt very good, and its (was) expensive, and it runs only under DOS.
- TASM is better, but still strives for MASM compatibility, which means millions of directives and tons of red tape. And its syntax is essentially MASMs, with the contradictions and quirks that entails (although it sorts out some of those by means of Ideal mode). Its expensive too. And its DOS-only.
So here, for your coding pleasure, is NASM. At present its still in prototype stage - we dont promise that it can outperform any of these assemblers. But please, please send us bug reports, fixes, helpful information, and anything else you can get your hands on (and thanks to the many people whove done this already! You all know who you are), and well improve it out of all recognition. Again.
Installing NASM under Unix
Once youve obtained the Unix source archive for NASM, nasm-X.XX.tar.gz (where X.XX denotes the version number of NASM contained in the archive), unpack it into a directory such as /usr/local/src. The archive, when unpacked, will create its own subdirectory nasm-X.XX.
NASM is an auto-configuring package: once youve unpacked it, cd to the directory its been unpacked into and type ./configure. This shell script will find the best C compiler to use for building NASM and set up Makefiles accordingly.
Once NASM has auto-configured, you can type make to build the nasm and ndisasm binaries, and then make install to install them in /usr/local/bin and install the man pages nasm.1 and ndisasm.1 in /usr/local/man/man1. Alternatively, you can give options such as --prefix to the configure script (see the file INSTALL for more details), or install the programs yourself.
NASM also comes with a set of utilities for handling the RDOFF custom object-file format, which are in the rdoff subdirectory of the NASM archive. You can build these with make rdf and install them with make rdf_install, if you want them.
If NASM fails to auto-configure, you may still be able to make it compile by using the fall-back Unix makefile Makefile.unx. Copy or rename that file to Makefile and try typing make. There is also a Makefile.unx file in the rdoff subdirectory.
Enhancements:
- adds 64-bit support "-f macho" output format "265th extern" bug in "-f obj" fixed(?)

Free Pascal (aka FPK Pascal) is a 32 or 64 bit (from 1.9.6) pascal compiler. Free Pascal Compiler is available for different processors Intel x86, Amd64/x86 64 (from 1.9.6), PowerPC (from 1.9.2), Sparc (from 1.9.6) and Motorola 680x0 (1.0.x only).
The following operating systems are supported Linux, FreeBSD, NetBSD, MacOSX/Darwin, MacOS classic, DOS, Win32, OS/2, BeOS, SunOS (Solaris), QNX and Classic Amiga.
Main features:
- Very clean language Pascal is a very nice language, your programs will be more readable and maintainable than for example in C, and lets even forget about C++. And you dont need to give up the power, the Pascal language is as powerful as you want it.
- No Makefiles Unlike most programming languages, Pascal does not need Makefiles. You can save huge amounts of time, the compiler just figures out itself which files need to be recompiled.
- Pascal compilers are Fast with a big F and Free Pascal is no exception. Yes, you no longer need to grow roots while compiling your programs, just hit the compile key and its done, even for large programs.
- Each unit has its own identifiers In Pascal you never need to worry about polluting the namespace, like in C where an identifier needs to be unique accross the entire program. No, in Pascal each unit gets its own namespace and thats very relaxed.
- Integrated development environment Free Pascal comes with an IDE which work on several platforms, in which you can write, compile and debug your programs. You will save huge amounts of time using the IDE, the best programming friend you have.
- Great integration with assembler Do you think pascal is for wimps who need to learn programming? WRONG! Its excellent for high tech programming and for the supreme nerds among you we have the integrated assemblers. You can easily mix assembler code and Pascal code, in the language you wish? Prefer Intel styled assembler? No problem, if its needed Free Pascal will convert it to ATT for you. Do you want to convert your program into a source file for Nasm? No problem, and all ATT assembler in your source files is automatically converted.
- Object oriented programming And if you do the serious programming, you are of course very interested in object oriented programming. Use the Turbo Pascal and Object Pascal ways of OOP according to your taste. The FCL and Free Vision and provide you with the powerful object libraries you need. For your database needs we support PostgreSQL, MySQL, Interbase and ODBC.
- Smartlinking Free Pascals smart linker leaves out any variable or code that you do not use. That makes small programs small with a big S, while they are still statically linked, avoiding DLL hell!
- Distribution independence (Linux) As a result of this, software compiled by the Linux version of Free Pascal runs on any Linux distribution, making it much, much, easier to make your software support multiple Linux distributions.
- Available for a lot of platforms on several architectures Free Pascal is available for more platforms than most other Pascal compilers and allows easy cross-compiling, just change the target in the IDE and compile! And there is work going on for even more platforms and processors.
- Compatible Have existing code? Free Pascal is more compatible with it than any other Pascal compiler. We are almost completely compatible with Turbo Pascal and quite well compatible with Delphi source code. If you have code in another language, like C or assembler, just use favorite compiler for it and call it from Free Pascal.
Version restrictions:
- For the intel 80x86 version at least a 386 processor is required, but a 486 is recommended. For the motorola 680x0 version, a 68020 or later processor is recommended. In all cases, a minimum of 8 Megabytes of RAM is recommended, but the compiler is reported to work with 4 Megabytes of RAM.

AsmFile is a small and fast file manager written in assembler.

AsmFile project uses a two pane interface like "mc" and other file managers. AsmFile runs in a console or a terminal window.

Assembly has been ignored by much of the Unix/Linux community and is almost never found in desktop applications. Some of the reasons for this are historical and related to portability. Other reasons include negative images of assembly and lack of tools. Today a small niche exists for assembly on the desktop. This will be explored here along with the supporting tools.

The resources section provides links to more information and places to discuss assembler topics. Of special interest to the author is a section of predictions and history. A email list for programmers interested in Desktop assembly is described in the resources section.

The AsmIDE family of programs are currently underdevelopment and some have reached a useful state.
