CompilerDirect link to the latest official files: source V0191, executables V0191, manual V046 German.The manual V042 is also available in English. Direct link to the nightly snapshot executables (caution - this may be a non-working development version) and the corresponding nightly snapshot sources. Versions after V0175 do no longer support the MARKER-specials. The corresponding functionallity is moved to a SJC-Annotation-special. If you need the old MARKERs, please use V0175. Versions beginning with V0177 support interface arrays, please adopt your runtime environment. I wrote a small compiler that translates some kind of java-subset into native code, either to run in an ia32 compliant protected mode or an amd64 compliant long mode. Furthermore you can produce code for a virtual machine with an unlimited amount of registers allowing almost write-once semantics for the used registers. Patrick Schmidt worked on an emulator for this machine, and also he helped to set up the backend for Atmel ATmega microcontrollers, thank you very much! Since version 180 there also exists a backend for ARM7 processors like LPC2103. The compiler requires Sun-Java to be compiled, after boot-strapping the compiler is able to compile itself. There are only few special things (namely the pseudo-classes MAGIC and STRUCT) that enable system programming in a typesafe language. The compiler is used to compile PicOS, Rainbow OS, parts of Wissenheim, the code for the ATmega demo board and a few private projects. The design is straight forward and extensible. You are welcome to write a new frontend (perhaps some Pascal style?) or a new backend (perhaps for another ARM processor?). For sure there are several bugs in this piece of software. If you need help doing something with my compiler or if you found a bug, please do not hesitate to contact me. There is a set of slides containing a short overview used at an invited speech on March 17th 2008. There is another set of slides containing a short overview used at an invited speech on October 5th 2010. The compiler is released under the GNU Public License, you can get the source code here. Please note that the copyright still belongs to me (Stefan Frenz) and, for the emulator and the basic ATmega backend, also to Patrick Schmidt, who is mentioned in the header of the regarding class files. If you like to edit the source code with the same Eclipse code style, you can download it here. All executable versions contain a small runtime environment and a README.TXT to get started.
