Abstract
Apparatus, methods, and computer program products are disclosed for optimizing programs containing single basic block natural loops with a determinable number of iterations. The invention optimizes, for execution speed, such program loops containing statements that are initially variant, but stabilize and become invariant after some number of iterations of the loop. The invention optimizes the loop by unwinding iterations from the loop for which the statements are variant, and by hoisting the stabilized statement from subsequent iterations of the loop.
