This report. One use was for a study of how well"C" programs would run on a CPU that did not easily support 32 bit pointers. Each time a pointer wasused, a couple of instructions were needed to form the 32 bit value. If this occurred too frequently, the programswould not run well on this hardware. A second use of these results was for estimating the cost ofmonitoring pointer references in a debugging system. If pointer references occur too frequently, the cost ofmonitoring would be...
