Large complex programs are composed of many small routines
|
|
|
|
|
that implement abstractions for the routines that call them.
|
|
|
|
|
To be useful, an execution profiler must attribute
|
|
|
|
|
execution time in a way that is significant for the
|
|
|
|
|
logical structure of a program
|
|
|
|
|
as well as for its textual decomposition.
|
|
|
|
|
This data must then be displayed to the user
|
|
|
|
|
in a convenient and informative way.
|
|
|
|
|
The \fBgprof\fP profiler
|
|
|
|
|
accounts for the running time of called routines
|
|
|
|
|
in the running time of the routines that call them.
|
|
|
|
|
The design and use of this profiler is described.
