Modulo scheduling is an effective instruction scheduling technique for exploiting ILP in modern microprocessors with wide machine resources.

This paper describes an approach to undo the effect of speculation optimization in modulo scheduled loops and thereby improve the quality of reverse engineering ...

Applying Data Speculation in Modulo Scheduled Loops. PACT '00: Proceedings of the 2000 International Conference on Parallel Architectures and Compilation ...

Speculation is used to increase both the overlap of the basic blocks within each iteration and the overlap of successive iterations. We extend modulo variable ...

• Enable data speculation. – Compiler optimistically assumes the memory operations do not alias with each other, and schedules them out of order. – Compiler ...

Under this scheduling framework, control speculation moves a speculative instruction to a dominating basic block. Speculations introduced by other phases, e.g..

In generalized loop execution, 1 bits must be shifted in during the prologue and kernel regions, speculative stage bits must be cleared on an exit condition,.
