This paper investigates the suitability of components generated using data clustering techniques. The suitability of the approach is based on real case studies from a commercial environment. Successive versions of the software application are used to investigate how the software applications change throughout the maintenance process. Within this paper, the change process as a whole is referred to as the process of software evolution. This paper provides an indication of how applications evolve over time and how clustering techniques are affected by the evolution process.","PeriodicalId":271895,"journal":{"name":"Proceedings.

We present techniques used in the asm2c translator, a SPARC assembly to C translator. The techniques involve data and control flow analyses. The data flow analysis eliminates machine dependencies from the assembly code and recovers high-level language expressions. The control flow analysis recovers control structure statements. Simple data type recovery is also done. The presented techniques are extensions and improvements on previously developed CISC techniques. The choice of intermediate representation allows for both RISC and CISC assembly code to be supported by the analyses. We tested asm2c against SPEC95 SPARC assembly programs generated by a C compiler. Results using both unoptimized and optimized assembly code are presented.","PeriodicalId":271895,"journal":{"name":"Proceedings. International Conference on Software Maintenance (Cat.

Because the questions underlying these problems are undecidable, no system can provide a completely fail safe certification. For example, in checking for memory leaks, a system can only warn of potential problems, but cannot guarantee that no leaks remain. We present an approach to modelling the dynamic memory access properties of a program using amorphous program slicing to create a Dynamic Memory Model (DMM). The slices are constructed from a transformed version of the original program in which heap access has been made explicit using a pseudo variable to denote the top of the heap. The DMM is a simplified version of the original program which is concerned solely with the dynamic memory access behaviour of the original. We illustrate the use of DMMs in problems of comprehension, verification and re-engineering. We introduce a proof-of-concept DMM construction algorithm, showing how slicing simplification power can be dramatically improved using domain-specific transformation rules.","PeriodicalId":271895,"journal":{"name":"Proceedings.

Textual differencing is a new, safe and fairly precise, selective regression testing technique that works by comparing source files from the old and the new version of the program. We have implemented the textual differencing technique in a tool called Pythia. Pythia has been developed primarily through the integration of standard, well known UNIX programs, and is capable of analyzing large software systems written in C. We present results from a case study involving a software system of approximately 11,000 lines of source code written for the European Space Agency. The results provide empirical evidence that textual differencing is very fast and capable of achieving substantial reductions in the size of the regression test suite.","PeriodicalId":271895,"journal":{"name":"Proceedings.

This approach builds new solutions via \"glue code\" using visual languages, which tie together client-based office products, server-based \"BackOffice\" products and web-based services/applications. The resulting collection of distributed object-oriented components are glued together by attaching code snippets written in a visual language to other components and controls, such as a command button on a form. A majority of the code in such an application is pre-generated and self-contained in the individual components being reused and, as a result, is typically difficult to understand and maintain. Our experience shows that, while these approaches actually exacerbate some maintenance problems, such as the introduction of dead code, traditional static analysis techniques may still facilitate common maintenance activities. This work reports on the use of data flow techniques on several medium-sized COTS integrated solutions that have become difficult to maintain. We found that by exploiting semantic information, traditional techniques can be augmented to handle some of the unique maintenance issues of component-based software.","PeriodicalId":271895,"journal":{"name":"Proceedings.

The focus of the effort is on the precise measurement of software development process and product outcomes. Tools and processes for the static measurement of the source code have been installed and made operational in a large embedded software system. Source code measurements have been gathered unobtrusively for each build in the software evolution process. The measurements are synthesized to obtain the fault surrogate. The complexity of sequential builds is compared and a new measure, code churn, is calculated. This paper demonstrates the effectiveness of code complexity churn by validating it against the testing problem reports.","PeriodicalId":271895,"journal":{"name":"Proceedings.

The two measurement programs were implemented in the software maintenance departments of two different organizations. Both programs were set up in roughly the same way. We use standard statistical techniques-principal component analysis and multiple regression analysis-to analyse the datasets. Surprisingly, with one of the datasets we are able to explain a fair amount of variance in the effort, while with the other dataset we can explain much less. From a closer inspection of the different environments we conjecture that the existence of a consistently applied process is an important prerequisite for a successful measurement program. In addition, if the process exists in multiple variants, it is important to know which variant is applied when.","PeriodicalId":271895,"journal":{"name":"Proceedings.
