Puma Concepts

Procedure Relationships

Figure 2-1 vanderbilt Procedure Relationships

To Puma, the relationships among procedures are dynamic, reﬂecting

the possibility that sometimes x may call y and later y may call x. Puma

analyzes your program as it is seen at run time; Puma does not base the

analysis on the lexical structure of the program as seen at compile time.

For example, if a procedure calls an error-handling routine, Puma would

report the error-handling routine as a child of the procedure only if,

during the execution of the procedure, control actually branched to the

error-handling routine and a sample was taken during the execution of

the error-handling routine.
