Open Source Assembly Compilers for Windows

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.

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.

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.

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.

SoftWire was the precursor to TransGaming's SwiftAsm. SwiftAsm is an optimizing run-time x86 assembler that can be used as a JIT compiler back-end for scripting languages, or for dynamic code generation of efficient processing pipelines.

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.

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

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++.

This is an attempt to add PERL's datatypes and flexibility to C/C++. While it is currently just a library, I intend to create a compiler for the language PERC (PERl + C. Plus I can make lots of caffeine puns, which is always good.).

Roc C++ IDE and Compiler

Steini\\\'s Mini Compiler is a fast DOS 16 bit compiler. Please help to improve the programming language writing new commands. The compiler uses a set of assembly files for the compilation process.

VirtuAL3101 provides a series of tools to develop effects using the AL3101 DSP from Alesis. It includes an assembler/disassembler, a simulator, an application generator with its graphical interface and various effects.

This is a port of Basic to NASM (B2Nasm) for visual basic.net. Basic to NASM is capable of file handling, output to and input from the console, arithmetic, and variable creation. A good starting point for native compiler creators.

Prolog to C compiler with runtime for DOS (with Turbo C), Windows 10 64 bits and Raspbian (Raspberry Pi)

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.

‘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.

Open Source Microsoft VC to Delphi translator is the translation utilities toolset with IDE that support translating Microsoft VC 7.0 projects, libraries, API’s to Delphi 7.0
