Abstract
A collection of ‘‘C’’ programs was measured for the number of dynamic references to pointers. The number of dynamic references to pointers is presenteded with respect to the total number of instructions a program executes, giving the percentage of pointer references executed in a ‘‘C’’ program. The measurements were done on a VAX 11/780 running the Berkeley UNIX operating system. The measured programs were selected by examining the most commonly run programs on the Computer Sciences Department UNIX machines. The measurement process was performed in two steps: (1) the dynamic counting of pointer references, and (2) the counting of the total number of instructions executed by the program.
