Open Source IBM AIX Compilers

"Aubit 4GL" is a project to make GPL, OpenSource, Informix-4GL compatible compiler, and continue to extend functionality needed to write most efficient and productive business related, database oriented applications. See "Home Page" link for more.

MLton is a whole-program optimizing compiler for Standard ML. MLton generates small executables with excellent runtime performance, utilizing untagged and unboxed native integers, reals, and words, unboxed native arrays, fast arbitrary-precision arithmetic based on GnuMP, and multiple code generation and garbage collection strategies. In addition, MLton provides a feature rich Standard ML programming environment, with full support for SML97 as given in The Definition of Standard ML (Revised), a number of useful language extensions, a complete implementation of the Standard ML Basis Library, various useful libraries, a simple and fast C foreign function interface, the ML Basis system for programming with source libraries, and tools such as a lexer generator, a parser generator, and a profiler.

z390 Portable Mainframe Assembler and Emulator

LLVM is a unique compiler infrastructure designed for the optimization of programs from arbitrary programming languages. Compilation in C and C++ programs is supported using a parser based on GCC 3.4. Backends exist for X86, Sparc, PowerPC and "C".

Butterfly programming language. A bytecode compiled scriping language. Bytecode architecture with separate compiler and interpreter/disassembler. Platform-independant bytecode based stackmchine, which has a fine arithmitical/raw-computing performance. B
