Can you explain a little bit more about what you mean by "randomize" functions or global variables? What aspect of them do you want to randomize? Their address? Their value? Something else? Reid.

By randomization of functions I mean the manner in whch they are called , so that has to do with address.I wish to randomize the order of calls made to functions when a program is run.

Tanu,
You've seen ? :-
http://www.st.cs.uni-sb.de/~lindig/src/quest/
Don't know whether it is applicable to what you are trying to achieve but I
thought I should point it out in case it is useful to you and you have not seen
it.

I would try that ..Thanks
Another thing that I want to do is to randomize functions within a program (or
file ), whatever is easier to do in llvm .Also please tell me how can I
randomize global variables ?
Thanks

There are two ways to do this:
1. Use the llvm-test harness
2. Use the official spec harness with -Wl,-native-cbe or -Wl,-native flags
to llvm-gcc.
