COMPILING FUNCTIONAL PROGRAMMING CONSTRUCTS to a LOGIC ENGINE by Harvey Abramson and Peter Ludemann Technical Report 86-24 November 1986
COMPILING FUNCTIONAL PROGRAMMING CONSTRUCTS TO A LOGIC ENGINE by Harvey Abramson and Peter Ludemann Technical Report 86-24 November 1986 Compiling Functional Programming Constructs to a Logic Engine Harvey Abramson t and Peter Ltidemann:I: Department of Computer Science University of British Columbia Vancouver, B.C., Canada V6T 1W5 Copyright © 1986 Abstract In this paper we consider how various constructs used in functional programming can be efficiently translated to code for a Prolog engine (designed by Ltidemann) similar in spirit but not identical to the Warren machine. It turns out that this Prolog engine which contains a delay mechanism designed to permit co routining and sound implementation of negation is sufficient to handle all common functional programming constructs; indeed, such a machine has about the same efficiency as a machine designed specifically for a functional programming language. This machine has been fully implemented. t Present address: Department of Computer Science, Bristol University, Bristol, England . f Present address: IBM Canada Ltd., 1 Park Centre, 895 Don Mills Road, North York, Ontario, Canada M3C 1W3 The proposals for combining the two paradigms Compiling Functional Programming have been roughly classified in [BoGi86] as being Constructs to a Logic Engine either functional plus logic or logic plus functional. Harvey Abramson t and Peter Ltidemanni In the former approach, invertibility, nondeterminism Department of Computer Science and unification are added to some higher order functional language; in the latter approach, first-order University of British Columbia functions are added to a first-order logic with an Vancouver, B.C., Canada V6T lWS equality theory. We do not take any position as to Copyright© 1986 which approach is best, but since a logic machine already deals with unification, nondeterminism and invertibility, we have taken, from an implementation Abstract viewpoint, the logic plus functional approach. -

Chapter 1 Basic Principles of Programming Languages
Chapter 1 Basic Principles of Programming Languages Although there exist many programming languages, the differences among them are insignificant compared to the differences among natural languages. In this chapter, we discuss the common aspects shared among different programming languages. These aspects include: programming paradigms that define how computation is expressed; the main features of programming languages and their impact on the performance of programs written in the languages; a brief review of the history and development of programming languages; the lexical, syntactic, and semantic structures of programming languages, data and data types, program processing and preprocessing, and the life cycles of program development. At the end of the chapter, you should have learned: what programming paradigms are; an overview of different programming languages and the background knowledge of these languages; the structures of programming languages and how programming languages are defined at the syntactic level; data types, strong versus weak checking; the relationship between language features and their performances; the processing and preprocessing of programming languages, compilation versus interpretation, and different execution models of macros, procedures, and inline procedures; the steps used for program development: requirement, specification, design, implementation, testing, and the correctness proof of programs. The chapter is organized as follows. Section 1.1 introduces the programming paradigms, performance, features, and the development of programming languages. Section 1.2 outlines the structures and design issues of programming languages. Section 1.3 discusses the typing systems, including types of variables, type equivalence, type conversion, and type checking during the compilation. Section 1.4 presents the preprocessing and processing of programming languages, including macro processing, interpretation, and compilation. -
Subroutines and Control Abstraction8 8.3.2 Call by Name
Subroutines and Control Abstraction8 8.3.2 Call by Name Call by name implements the normal-order argument evaluation described in Section 6.6.2. A call-by-name parameter is re-evaluated in the caller’s referencing environment every time it is used. The effect is as if the called routine had been textually expanded at the point of call, with the actual parameter (which may be a complicated expression) replacing every occurrence of the formal parameter. To avoid the usual problems with macro parameters, the “expansion” is defined to include parentheses around the replaced parameter wherever syntactically valid, and to make “suitable systematic changes” to the names of any formal parame- ters or local identifiers that share the same name, so that their meanings never conflict [NBB+63, p. 12]. Call by name is the default in Algol 60; call by value is available as an alternative. In Simula call by value is the default; call by name is the alternative. Toimplement call by name,Algol 60 implementations pass a hidden subroutine that evaluates the actual parameter in the caller’s referencing environment. The hidden routine is usually called a thunk.2 In most cases thunks are trivial. If an actual parameter is a variable name, for example, the thunk simply reads the EXAMPLE 8.68 variable from memory. In some cases, however, a thunk can be elaborate. Perhaps Jensen’s device the most famous occurs in what is known as Jensen’s device, named after Jørn Jensen [Rut67]. The idea is to pass to a subroutine both a built-up expression and one or more of the variables used in the expression. -

Design, Semantics and Implementation of the Ptolemy Programming Language: A Language with Quantified yT ped Events Abstract Implicit invocation (II) and aspect-oriented (AO) languages provide software designers with related but distinct mechanisms and strategies for decomposing programs into modules and composing modules into systems. II languages have explicitly announced events that run registered observer methods. AO languages have implicitly announced events that run method-like but more powerful advice. A limitation of II languages is their inability to refer to a large set of events succinctly. They also lack the expressive power of AO advice. Limitations of AO languages include potentially fragile dependence on syntactic structure that may hurt maintainability, and limits on the available set of implicit events and the reflective contextual information available. -

Signed by the final examining committee: Dr. Jia Yuan Yu Chair Dr. Lingyu Wang Examiner Dr. Zhenhua Zhu External Examiner Dr. Mohammad Mannan Supervisor Approved Chair of Department or Graduate Program Director 2016 Dr. Amir Asif, Dean Faculty of Engineering and Computer Science Abstract On Matching Binary to Source Code Arash Shahkar Reverse engineering of executable binary programs has diverse applications in computer security and forensics, and often involves identifying parts of code that are reused from third party software projects. Identification of code clones by comparing and fingerprinting low-level binaries has been explored in various pieces of work as an effective approach for accelerating the reverse engineering process. Binary clone detection across different environments and computing platforms bears significant challenges, and reasoning about sequences of low-level machine in- structions is a tedious and time consuming process. Because of these reasons, the ability of matching reused functions to their source code is highly advantageous, de- spite being rarely explored to date. -

During the overall traffic by 20% [6]. These numbers are likely worse execution, such applications spend a significant amount of time on modern computers where pages load faster and faster, making communicating with the database for retrieval and storing of per- it increasingly important to reduce the amount of time spent on sistent data over the network. These network round trips represent database queries. Second, ORM frameworks can greatly increase a significant fraction of the overall execution time for many appli- load times by performing additional queries to retrieve objects that cations and as a result increase their latency.
