This report presents a new version of Structure Splitting optimization, implemented for compiler for Elbrus and SPARC processors. Structure Splitting tries to improve data locality by splitting arrays of structures into arrays of smaller structures. The optimization was generalised for the case of array of structures nested in another structure and possibility of its reallocation. Execution speed of two tests from SPEC CPU2000 and SPEC CPU2006 increased by 19% and 12%.
In addition, the report presents algorythm for hand application of described optimization.
