WebVariables j and t4 decrease by 4 thereby form an example of a pair of induction variables. When there exists two or more induction variables in a loop, it is possible to get rid of all but one. Looking at the inner loop of B3 in [image 5] , we can't remove either j or t4 completely since t4 is used in B3 and j is used in B4 . WebThe compiler often introduces induction variables to help it to implement the loop. When properly transformed, we may be able to eliminate some variables and apply strength reduction to others. A nested loop is a good example of the use of induction variables. Here is a simple nested loop: for (i = 0; i WebFor example, Loop-invariant code is partially redundant and can be eliminated by using a code-motion technique. Another example of a partially redundant code can be: If … cybersecurity markt nederland

WebThis form of strength reduction can be typically applied to induction variables (i.e., to variables whose values are functions of the loop iteration values), and in some cases can lead to the elimination of the induction variable (induction variable elimination) altogether as shown in the example code in Fig. 5.1C.
