Abstract
Code motion and redundancy removal based on an Extended Global Value Numbering technique which performs value numbering beyond basic blocks and extended basic blocks. Full redundancies and partial redundancies are identified and iteratively processed until they are no longer movable or removable in the program. The identification and processing is aided by the use of Value Number Lists and Value Number Sets. Provides improved optimization of redundancy and partial redundancy with reduced compilation time and reduced storage.
