MPL Bytecode Compiler

NEWS: The MPL language is now completely defined. No more language changes are to be made. The compiler is complete and should be easy to translate to other languages if you so choose. MPL is a small, simple language based on BCPL, B, C and Jesusonic. The compiler and interpreter are written in portable Pascal. I have successfully compiled MPL for CP/M, DOS, Windows, Atari ST, Amiga and the Tandy Colour Computer. MPL is designed to be tiny in every way, while implementing all the important features of BCPL & B. The result is a compiler written in a high level language (PASCAL) which compiles to under 16K (CP/M). The symbol table, language syntax, and bytecode are all optimized for size. I will write a MPL Reference Manual in time. Contact myself if you want to help get that written.

SUNY Pascal

This Pascal compiler was created by the Computer Science Department of SUNY in Stony Brook back in 1975. The Pascal compiler generates code for the IBM 360 and is written in XPL. This project includes the source code for the Pascal compiler and the XPL compiler. This project also includes an IBM/360 simulator capable of running the output of both the Pascal compiler and the XPL compiler. The simulator is written in C and can run on most machines with a C compiler.

pascal-p2

This was the 2nd version of the Pascal-P compiler created by Niklaus Wirth's group at ETH Zurich, termed Pascal-P2. This was the original portable compiler for Pascal. Niklaus Wirth led an effort to gather and reconcile the different sources for the Pascal-P compiler in existence, which were collectively referred to as Pascal-P1.These were then published as part of a porting kit for the compiler. Pascal-P2 is a "Running history project". It is a historical record, but still runs on modern computers. Pascal-P2 exists mainly for historical reference. It was improved at ETH Zurich to become Pascal-P4, and brought to full ISO 7185 standard status as Pascal-P5. You can find all of the Pascal-P versions here in sourceforge: https://sourceforge.net/projects/pascal-s/ https://sourceforge.net/projects/pascal-p2/ https://sourceforge.net/projects/pascalp4/ https://sourceforge.net/projects/pascalp5/ https://sourceforge.net/projects/pascal-p6/

Tiger

Tiger is a Delphi-hosted compiler infrastructure that lets you generate native x86-64 binaries for Windows and Linux — executables, shared libraries, static libraries, and object files — entirely from code. There is no source language to parse. Instead, you construct programs using a fluent Delphi API: define types, declare functions.

Oz-CocoR-Delphi

Coco/R is a compiler generator, which takes an attributed grammar of a source language and generates a scanner and a parser for this language. The scanner works as a deterministic finite automaton. The parser uses recursive descent. LL(1) conflicts can be resolved by a multi-symbol lookahead or by semantic checks. Thus the class of accepted grammars is LL(k) for an arbitrary k.
