I am doing research in the area of software protection, including
ofucaation, tamper resistance, and watermarking. I took a compiler
course 10 years ago so I am little rusty. I would like to create a
pre-compiler that that took a source code (C++) input and tranformed
all the function names and constants. For example, a source function
might be GetFirstName(...), and the transformed function name might be
aa(...) where the actual implementation of GetFirstName() and aa() are
identical.The tranformed output of the pre-compiler would then be run
through normal C/C++ compiler.


          Is there any sample compiler source code available that does
anything remotely similar to the above or can anyone give me any
suggestions on a quick proof of concept implementation of my own?


      Cheers
