| 25 | Programs the size and complexity of compilers | |
| 26 | are composed of a large number of small routines, | |
| 27 | each implementing an abstraction for the routines | |
| 28 | that call it. | |
| 29 | To be useful, an execution profiler must attribute | |
| 30 | execution time in a way that is meaningful in terms of the | |
| 31 | logical structure of a program | |
| 32 | as well as its decomposition. | |
| 33 | The information must then be displayed to the user | |
| 34 | in a convenient and informative way. | |
| 35 | The \fBgprof\fP profiler described in this paper | |
| 36 | incorporates the running time of called routines | |
| 37 | in the running time of the routines that call them. | |
| 38 | The design and use of this profiler is described. |
