Open Source Assembly Code Generators

Open-source, free, multi-platform BASIC compiler, with syntax similar MS-QuickBASIC (including the GFX statements), that adds new features such as pointers, unsigned data types, inline assembly, a pre-processor and many others.

An open source COBOL compiler for the PC x86-32 platform. Generates GNU assembler and requires GCC to produce a binary. Supports Linux, BSD and MinGW 32 bit platforms.

z390 Portable Mainframe Assembler and Emulator

ImpLib SDK combines free programming tools for authoring custom import libraries for Windows DLL (32 and 64 bit). The SDK supports advanced features, like cdecl2stdcall conversion, importing by ordinal, removing original thunk, storing symbols from different DLL files in a single import library. The ImpLib SDK is also useful to overcome any legal restrictions when redistributing the import libraries for certain DLL files, like the Microsoft® C++ runtime. The import libraries for the CRT or STL are part of the Windows SDK. Even though the SDK is available for free, redistributing these files is not allowed according to the current license agreements. An alternative is to generate these import libraries using the ImpLib SDK, as it doesn't restrict redistribution. The ImpLib SDK is free even for commercial use and redistribution of any kind, as long as all copyrights are preserved.

Adebug/Assemble is a pair of Debugger/Assembler for the MC68Xxx family running on Atari and Amiga computers. Years ago commercial product, now GPL.

pyz80 is a z80 cross-assembler written entirely in Python. It accepts text files with the syntax of the Sam Coupe's popular COMET assembler, and outputs a disk image suitable for loading in SimCoupe or transferring to floppy disk for use with a real Sam.

A full development kit, based on XSCompiler. Multi-platform compiler and IDE, many libraries and examples. Uses an innovative programming language, an improved version of the standard and well-known C/C++.

VB62VC6 - Visual Basic 6 sources to Visual C++ 6 converter.

Vincent ES 1.x is a 3D rendering library based on the OpenGL (R) ES 1.1 API specification (Common Lite) for embedded devices. ATTENTION: A new fixed pipeline implementation is being work on here: https://sourceforge.net/projects/oglsc

Compiler for a Forth-like language to make small binaries that use system calls instead of the C library

This project aims to create an ARM processor emulator for Linux/x86, utilising dynamic binary translation techniques for maximum speed.

CSpe is a library allowing partial function application in C (kindof like closures in ML languages) : From a function to be specialized and some of its arguments, it dynamically generates a new function pointer, which can then be called transparently

The easiest way to seamlessly integrate the Lua scripting language into any C/C++ project. CaLua allows you to expose C structures and functions to Lua scripts, and expose Lua functions to C programs, with the use of a few simple C functions.

Utilities that enable software development for the Casio fx-9860G calculator.

A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.

CodeXpand Engine is a Scripting engine written with C++. It work with COMPILED SCRIPT linked at Run Time with Host Applications. The SCRIPT COMPILER generate the CPU bytecode requested from the Host CPU where the application (& the scripts) will run.

Digital Signal Processing Block Diagram Compiler - user extendable to all DSP's, but presently supports only the TI C2000 family. Rich support for fixed point arithmetic, both saturated and unsaturated. Block diagram entry is via TinyCAD (included).

GoldRec is a generic Dynamic Compiler target at emulators in general including 64bit processor support and code optimizations.

‘intelliworm’ is a prototype simulation of a Intelligent Species of a common earth worm,which inherits human like decision making capabilities through Neural Network intelligence representation,all developed by integrating .NET with Lisp and Yacc.

Object Oriented Progamming for Assembly Language - Javalin enables the assembly language programmer to define and create portable object packages using the Javalin object oriented programming model.

Toolchain machinery for compilers, code generators, assemblers, linkers, and emulators.

Introduction: A set of macros to provide C/Pascal -like structures in assembly program: if-else-endif, while-endWhile, repeat-until, switch-EndSwitch, for-EndFor, downFor-EndDownFor, try-catch-finally-EndTry. Objective: Encourage writing of assembly
