...e instruction in the function but in the case where there is none (i.e. the argument is passed on directly to another function), creating a store does not help to get the memory address of the variable which takes me back to my initial question at http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-May/022590.html - isn't there a way to obtain the address of an argument? Because doing a store seems to copy the variable and expose the address of the copy - http://www.llvm.org/docs/LangRef.html#i_store is not very clear on what's going on. You can imagine that if you try to do something like tain...

Nick, Thanks for the quick answer. Dereferencing the pointer does yield the same result in both cases but that's not what I want to do. I want to instrument the program dynamically and keep track of certain memory locations which is a problem if the same variable has different addresses for the static/dynamic code - as far I see this is what it's happening but I have no clue why.
