Visualizing Program Slices
Program slicing is an automatic technique for determining which code in a program is relevant to a particular computation. Slicing has been applied in many areas, including program understanding, debugging, and maintenance. However, little attention has been paid to suitable interfaces for exploring program slices. We present an interface for program slicing that allows slicing at the statement...
متن کاملUnion Slices for Program Maintenance
Owing to its relative simplicity and wide range of applications, static slices are specifically proposed for software maintenance and program understanding. Unfortunately, in many cases static slices are overly conservative and therefore too large to supply useful information to the software maintainer. Dynamic slicing methods can produce more precise results, but only for one test case. In thi...
متن کاملUnderstanding Program Dependencies
This paper reports on an experiment in trying to understand anunfamiliar program of some complexity and to record the authors’ under-standing of it. The goal was to simulate a practicing programmer in aprogram maintenance environment using the techniques of program designadapted to program understanding and documentation; that is, given aprogram, a specification and correctn...
متن کاملUnderstanding the Backward Slices of Performance Degrading Instructions Craig
For many applications, branch mispredictions and cache misses limit a processor's performance to a level well below its peak instruction throughput. A small fraction of static instructions, whose behavior cannot be anticipated using current branch predictors and caches, contribute a large fraction of such performance degrading events. This paper analyzes the dynamic instruction stream leading u...
متن کاملAn Efficient Algorithm for Computing all Program Static Slices
Program slicing is the task of finding all statements in a program that directly, or indirectly, influence the value of a variable occurrence. The set of statements that can affect the value of a variable at some point in a program is called a program backward slice. In several software engineering applications, such as program debugging and measuring the program cohesion and parallelism, sever...
