An investigation into concurrent semantic analysis

V. Seshadri, D. B. Wortman
1991 Software, Practice & Experience  
These solutions are then implemented as part of a concurrent Modula-2+ compiler, running on a shared memory multiprocessor.  ...  This paper investigates the problems involved in designing the semantic analyser for a concurrent compiler for a modern, block-structured language.  ...  A speed-up of 2·3 to 3·1 on five processors was reported when compiling large programs, whereas a speed-up of 1·0 to 2·0 was reported for smaller programs.  ...

1988 Proceedings of the ACM SIGPLAN 1988 conference on Programming Language design and Implementation - PLDI '88  
The authors are currently engaged in a project to devise ways of structuring compilers so that they can take advantage of modem multiprocessor hardware.  ...  This paper is about the most difficult aspect of concurrent compilation: concurrent semantic analysis.  ...  Most of the theoretical work on concurrent compilation has concentrated on parsing.

A lightweight approach for migrating web frameworks

Ahmed E. Hassan, Richard C. Holt
2005 Information and Software Technology  
In the fast paced world of web applications, new frameworks are introduced and old ones are updated frequently. A framework is chosen during the initial phases of the project.  ...  We give an example of using our approach to migrate a web application written using Active Server Pages (ASP) framework to Netscape Server Pages (NSP) framework.  ...  In particular, we would like to thank Wai-Ming Wong from Sun for his assistance in our study of the web applications. We would also like to thank Thomas R. Dean, James R.  ...

Eliminating virtual function calls in C++ programs [chapter]

Gerald Aigner, Urs Hölzle
1996 Lecture Notes in Computer Science  
For more call-intensive versions of the same programs, performance improved by a median of 26% and the number of virtual calls dropped by a factor of 17.5.  ...  over 90,000 lines of code by a median of 18% over the original programs and reduces the number of virtual function calls by a median factor of five.  ...  Bacon, Jeff Dean, and Dave Grove for their comments on earlier versions of this paper.  ...

Pragmatic aspects of reusable program generators

NORMAN RAMSEY
2003 Journal of functional programming  
How should a user control variations? This paper elaborates on these questions by means of case studies of the New Jersey Machine-Code Toolkit, the λ-RTL Translator, and the ASDL program generator.  ...  Most urgently needed are a standard way to support multiple target languages and a simple, clear way to control interfaces to generated code. 1. What does the generated code do? 2.  ...  The comments of JFP's anonymous referees were unusually helpful. In particular, reviewer C suggested a restructuring that improved the paper immeasurably.  ...

A critique of Standard ML

Andrew W. Appel
1993 Journal of functional programming  
There are many aspects of the language that work well.However, nothing is perfect: Standard ML has a few shortcomings.  ...  AbstractStandard ML is an excellent language for many kinds of programming. It is safe, efficient, suitably abstract, and concise.  ...  Acknowledgment I would like to thank Doug McIlroy and an anonymous referee for many valuable comments.  ...

An infrastructure to support interoperability in reverse engineering

Nicholas A. Kraft, Brian A. Malloy, James F. Power
2007 Information and Software Technology  
The three major components of the infrastructure are: (1) a hierarchy of schemas for low-and middle-level program representation graphs, (2) g 4 re, a tool chain for reverse engineering C ++ programs,  ...  The results of two case studies that investigated the space and time costs incurred by the infrastructure are provided.  ...  The fastest parsing times in this case study were for uncompressed GXL encodings of linked instances of the CppInfo schema. For the 12 test cases, these files took just over 2 minutes to parse.  ...

Reflections on standard ML [chapter]

David B. MacQueen
1993 Lecture Notes in Computer Science  
Standard ML is one of a number of new programming languages developed in the 1980s that are seen as suitable vehicles for serious systems and applications programming.  ...  Because of its type and module system, Standard ML manages to combine safety, security, a n d robustness with much of the exibility of dynamically typed languages like Lisp.  ...  A couple of intriguing and potentially useful variations on datatype de nitions have been suggested.  ...
