----------------- Hello, I want to do a memory dependence profiling. Is there any freely available implementation of memory dependence profiling implementations in LLVM which I can modify for my own use?

E. g. do you mean accesses to memory locations or object inter-dependencies or ... ?

It uses alias analysis, so maybe you want to have a look on that too.
