LLVM based project idea in computer security

Hello,

First, I apologize if this is the wrong list for my inquiry. I am a student at UCSB working in Computer Security and I had an idea that would make heavy use of llvm. The idea is to use llvm as an IR / compiler for dynamic binary instrumentation, along the lines of the VEX IR in the valgrind tool. I was wondering if this idea had been previously discussed or if someone is currently working on it?

My hope is that llvm, given its highly portable nature, will be more conducive to cross platform support. My dream is to have a highly portable tool similar to valgrind, although I am aware that much of the difficulty in porting valgrind does not stem from it's IR representation but rather dealing with system calls specific to the OS (which on windows will probably make writing any type of dynamic binary instrumentation tool the closest thing to working in hades).

Anyway, I am in the process of doing my due diligence, checking for previous work and related topics. I would very much appreciate input on this subject and I thank you for your time :slight_smile:
