Thanks for the feedback thus far! I've updated the header file, and enclosed a complete patch against LLVM. This passes all the regtests, and I'll be doing more thorough testing of LLVM itself with the patch. I've included some basic unit tests, but could probably do more here... Not sure it's worth delaying the initial submission though, as the best testing is to use a hash

Hello folks, TL;DR: This is my proposed hashing interface based on a proposed standard hashing interface. It also is implemented with a much faster and higher quality algorithm than the current one. This is an *early draft* of the code, looking for initial feedback. There has been recent interest in improving the quality and consistency of LLVM's approach to hashing. In particular, getting
