Abstract
Loop instructions are analyzed and assigned stage numbers based on dependencies between them and machine resources available. The loop instructions are selectively executed based on their stage numbers, thereby eliminating the need for explicit loop set-up and tear-down instructions. On a Single Instruction, Multiple Data machine, the final instance of each instruction may be executed on a subset of the processing elements or vector elements, dependent on the number of iterations of the original loop.
