...nvolving at least two multiplications and one addition) hence it actualy should have been moved out of the inner loop. At the very least inside the loop it should have been calculated once , and not twice. Anyway this is just a syptom of a general phenomenon in which it seems my LLVM assumes that getelemenptrs are atomic and it does not try to do any optimization on them. Can someone tell me if there is a known solution /existing code transformation that does the optimization ?

LLVM assumes that the code generator will handle this optimization when the getelementptr's are lowered into integer arithmetic. Many things can only be optimized after lowering in the code generator, and LICM of simpl...
