I am currently working on a project to migrate over 500,000 lines of
80186 assembler to C. This uses the FermaT transformation system,
http://www.cse.dmu.ac.uk/~mward/fermat.html, to do the (essential)
extensive analysis of the code. A proprietary assembler to WSL
translator translates the assembler source code into WSL (a wide
Spectrum Language which is particularly designed for program analysis
and transformation).


Extensive WSL to WSL transformations are carried out automatically
using the FermaT transformation system (the core of the system and
most of the transformations are freeware, but this project also uses
some proprietary x86-specific transformations). The transformations
include control flow restructuring, dataflow analysis and computing
control dependencies, constant propagation, and copy propagation.


Finally, the restructured WSL code is translated to C via another
proprietary translator.


More details, including a case study paper, will be made available on
completion of the project, but please feel free to email me if you are
interested.
