A method for transforming access to a structure array, that includes compiling source code, wherein compiling the source code includes identifying the structure array in the source code, performing an object safety analysis to determine whether the structure array is safe for transformation, wherein the object safety analysis includes an inter-procedural alias class analysis, performing a profitability analysis on the structure array when the structure array is safe for transformation, wherein the profitability analysis includes selecting a transformation from a plurality of transformations, wherein the plurality of transformations includes a pointer based fully splitting transformation, a pointer based partially splitting transformation, and an address based fully splitting transformation, and performing the selected transformation on the structure array, and storing the compiled code.
