A method for improving program performance including reordering a global data area of a program and for each load instruction referencing global variables within range of the immediate part of an add immediate instruction from a TOC anchor, replacing the load instruction with an add immediate instruction. The method may further include placing a TOC at the top, or within a predetermined distance from the top, of the global data area. The method may also include placing the global variables after the TOC, wherein more frequently referenced global variable are closer to the TOC than less frequently referenced global variables. Also, the method may further include placing in run-time order, groups of the global variables that frequently follow each other in run-time.
