Pascal-F, A portable Fortran-based Pascal Compiler

Joseph Manning · Open Collections · 2010

This thesis examines the subject of compiler portability and describes a project which adopts one particular approach to achieving this goal: generate code in an existing widely-implemented language as output from the compiler. Pascal-F translates Pascal to F-code, an intermediate language which can be processed directly by any Standard FORTRAN compiler. The design of the F-code machine is treated in detail, and problems with the use of FORTRAN as a target language are discussed.

A parallelizing compiler for Pascal

Maulik A. Dave, Y. N. Srikant · NOT FOUND REPOSITORY (Indian Institute of Science Bangalore) · 1991

A parallelizing compiler takes as its input a program in a sequential language such as FORTRAN or Pascal and after extracting parallelism which is implicit in it, generates code which is suitable for execution on a parallel processor. The authors have used Pascal for their compiler as it has extra features such as recursion, pointers, record structures and nesting of procedures. The aim is to extract the maximum parallelism in a reasonable time. Instead of flowgraphs, the concept of boxgraphs has been developed and implemented. An algorithm has been implemented to carry out simple and interprocedural dataflow analysis, array subscript analysis, to detect parallelism in boxgraphs and to convert them into boxgraphs depicting parallelism explicitly. The compiler generates code for the ORG Supermax machine, a shared memory multiprocessor with two 68020 processors running on the UNIX operating system V.3 (38 refs.)

An algebraic specification of a Pascal compiler

Joëlle Despeyroux · ACM SIGPLAN Notices · 1983

There is a growing interest in abstract data types as a tool for specifying semantics of programming languages and for specifying translations. This paper present the first large scale experience in this area. An algebraic semantics of Pascal, using abstract data type is given. Then an algebraic semantics of the low-level language P-Code is given. Finally a specification of a compiler from Pascal to P-Code, by means of implementation of abstract data types, is given, with a small example of translation.

Code optimisation for the NZTAB Pascal compiler

Ian M. Douthwaite · University of Canterbury Research Repository (University of Canterbury) · 1983

The aim of this project was optimisation of the code produced by
\nthe NZTAB Pascal compiler. This compiler is used for almost all
\nthe code in the TAB's nationwide betting system. The desire to
\nimprove the performance of the code was prompted by two reasons:
\n* Certain heavily-used parts of the code are presently written in
\nassembler for efficiency. For maintainability, it would be
\nbetter to have all code written in Pascal.
\n* The performance of the betting system is significantly affected
\nby certain system control functions.
\nThe TAB wished to pursue the adding of an optimisation stage to
\nthe compiler so that performance might be improved in that way.
\nThe task of this project, then, was to consider the problem of
\nadding optimisation to the TAB compiler, assessing possible
\noptimisation techniques, and implementing the best of these.
\nThere are several aspects to this project and the structure of
\nthis report reflects that. This does not mean, however, that each
\naspect represents a chronological phase. The first section deals
\nwith the problem and with the constraints placed on possible
\noptimisation methods. Section two briefly presents various kinds
\nof optimisations that are often done and reviews the main methods
\navailable for doing them. In section three there is an analysis
\nof the nature of the code currently produced by the TAB compiler
\nand the implications of this for optimisation. Fourthly, various
\noptimisation strategies that were considered are presented with their problems and advantages. Section five deals with two
\nstrategies for which some implementation was done, with the
\nproblems that arise in their implementation, and with their
\npotential benefits. Finally, in section six, some questions are
\nposed that are relevant to if and how the project should proceed
\nand some recommendations are given.
\nNaturally, the ideal result of such a project would have been the
\ncompletion of an optimiser that performed sufficiently well for
\nthe earlier goals to be realised: this has not been achieved.
\nOne should remember though that this project can viewed in two
\nways. In one way it can be seen as being required to add some
\nform of optimisation to a Pascal compiler. At the other level,
\nhowever, it can be seen as ryeeding to provide optimisation that
\nis sufficient for the goals given at the start of this
\nintroduction, and that is obtained in a way that is acceptable to
\nthe TAB environment. This latter goal is far more difficult but
\nit is towards this goal that the efforts of this project have
\nbeen directed.

Direct implementation of compiler specifications or the pascal p-code compiler revisited

Don Milos, Uwe F. Pleban, George J. Loegel · 1984

We have developed a complete formal specification of the translation semantics of the Pascal P-compiler. The specification is written as a semantic grammar (a variant of extended attribute grammars), and has been extensively tested and debugged with the aid of Lawrence Paulson's experimental semantics processor. The translation semantics models the operational aspects of compilation in detail. It is one-pass, embodying static semantic checking, address assignment, code generation, and a certain amount of code improvement. Our paper describes the development history of the project, compares the new compiler with the existing P-compiler, and discusses our positive experience with semantic grammars and Paulson's system.

High-level Debugging Systems for Pascal: Interpreter versus Compiler

Michael Hirsch, Stephen R. Schach, Willem R. Van Biljon · Unisa Institutional Repository (University of South Africa) · 1985

Two approaches to high-level debugging systems for Pascal are&#13;\ncompared, namely the use of a debugging precompiler as against a debugging&#13;\ninterpreter. A description is given of a high-level Pascal debugging&#13;\ninterpreter which has the power of the precompiler approach,&#13;\nbut with none of the disadvantages.

Construction of a transportable, multi-pass compiler for extended Pascal

Gilbert J. Hansen, G. A. Shoults, J. D. Cointment · ACM SIGPLAN Notices · 1979

This paper describes the implementation of an extended Pascal compiler on the TI 990 minicomputer, the TI 980 minicomputer, and the IBM System 370. The compiler was designed to be as machine independent as possible; the parser and machine independent optimizer are parameterized so they are identical at the source code level for all machines. The paper describes the language modifications and extensions to Pascal, the parser, the optimizer, and the code generators. In addition, the intermediate language utilized is discussed at length.
