Open Source Compilers

SSEPlus is a SIMD function library. It provides optimized emulation for newer SSE instructions. It also provides a rich set of high performance routines for common operations such as arithmetic, bitwise logic, and data packing and unpacking.

The Wittgen programming language consists of just two instructions and one special variable name. Wittgen allows you to assign any text string to a variable of any name. It also allows you to retrieve the text assigned to that variable. Lastly, it has a special variable called “Doing Now”. Every execution step consists of retrieving the contents of Doing Now, removing the first assign found in that content and performing that assign. In the course of performing that assign any retrieve operations indicated in the text are performed before committing the assign. That is all there the system does. The driving motivation for this design is that as far as we know, the human mind supports these two instructions.It may have additional mechanisms that create new assigns, but using the results of these mechanisms requires a system built from these instructions.

Cross-platform C++ library for Reverse Polish Notation calculus. Focuses on providing a reusable set of RPN functionalities such as parsing, variable substitution and computation.

Hipo is a hypothetical computer to facilitate the learning of machine language. The student can use hipo to develop simple programs and understand the internal logic of a computer. There is a plan to implement Donald Knuth's MMIX machine language, also.

**NOTE**: The WALA project is now hosted at https://github.com/wala/WALA; the latest source code and updates are available there. The code here on Sourceforge is highly out of date and unsupported. The T. J. Watson Libraries for Analysis (WALA) provide program analysis capabilities for Java bytecode and related languages. The WALA libraries constitute an open-source release of parts of IBM Research's DOMO analysis infrastructure.

Can emulate old computer on text the code pogram ideal to create kernel for operating system The begin the project the can emulate CPU(8080)and z80.

jpaul is a Java implementation of several algorithms widely used in program analysis. It emphasizes flexibility and ease-of-use and is independent of any specific compiler infrastructure project. BSD Licence.
