Pascal-86 hasn't been popular since the 80's when programming on DOS systems, but as work on a master's thesis John Törnblom decided to write a Pascal-86 front-end for LLVM. John's thesis was entitled "Improving Quality of Avionics Software Using Mutation Testing." This compiler front-end to Pascal-86 was written entirely in Python with the code generation then being handled by LLVM. This LLVM front-end supports most of Pascal-86's language constructs, support for several mutation operators, the ability to re-generate Pascal-86 source code, and allowing for mutants to be visualized via a web interface.
John Törnblom wrote into Phoronix to share this work for those that might be interested in toying around with this LLVM-based Pascal-86 work. His thesis can be read at liu.diva-portal.org while his new LLVM front-end is hosted on GitHub.
