Application To Strength Reduction
A common compiler optimization is to recognize the existence of induction variables and replace them with simpler computations; for example, the code above could be rewritten by the compiler as follows, on the assumption that the addition of a constant will be cheaper than a multiplication.
j = -17; for (i = 0; i < 10; ++i) { j = j + 17; }This optimization is a special case of strength reduction.
