I have started my work by trying to see if a simple for loop can be paralellised in llvm.. The problem is i want to know how to check if a program is automatically parallelised when compiled with llvm or if explicitly need to do it how can i go about paralellising a for loop using llvm compiler infrsatructure.how do i check for data dependency between iterations using llvm.</div>
