Design and Implementation of Generics for the .NET Common Language Runtime

The Microsoft .NET Common Language Runtime provides a This paper describes the design and implementation of support shared type system, intermediate language and dynamic execution for parametric polymorphism in the CLR. In its initial release, the environment for the implementation and inter-operation of multiple CLR has no support for polymorphism, an omission shared by the source languages. In this paper we extend it with direct support for JVM. Of course, it is always possible to “compile away” polymor- parametric polymorphism (also known as generics), describing the phism by translation, as has been demonstrated in a number of ex- design through examples written in an extended version of the C# tensions to Java [14, 4, 6, 13, 2, 16] that require no change to the programming language, and explaining aspects of implementation JVM, and in compilers for polymorphic languages that target the by reference to a prototype extension to the runtime. JVM or CLR (MLj [3], Haskell, Eiffel, Mercury). However, such Our design is very expressive, supporting parameterized types, systems inevitably suffer drawbacks of some kind, whether through polymorphic static, instance and virtual methods, “F-bounded” source language restrictions (disallowing primitive type instanti- type parameters, instantiation at pointer and value types, polymor- ations to enable a simple erasure-based translation, as in GJ and phic recursion, and exact run-time types. -

The Basics of Exception Handling
The Basics of Exception Handling MIPS uses two coprocessors: C0 and C1 for additional help. C0 primarily helps with exception handling, and C1 helps with floating point arithmetic. Each coprocessor has a few registers. Interrupts Initiated outside the instruction stream Arrive asynchronously (at no specific time), Example: o I/O device status change o I/O device error condition Traps Occur due to something in instruction stream. Examples: o Unaligned address error o Arithmetic overflow o System call MIPS coprocessor C0 has a cause register (Register 13) that contains a 4-bit code to identify the cause of an exception Cause register pending exception code interrupt Bits 15-10 Bits 5-2 [Exception Code = 0 means I/O interrupt = 12 means arithmetic overflow etc] MIPS instructions that cause overflow (or some other violation) lead to an exception, which sets the exception code. It then switches to the kernel mode (designated by a bit in the status register of C0, register 12) and transfers control to a predefined address to invoke a routine (exception handler) for handling the exception. Interrupt Enable Status register Interrupt Mask 15-8 1 0 Kernel/User (EPC = Exception Program Counter, Reg 14 of C0) Memory L: add $t0, $t1, $t2 overflow! Return address (L+4) Exception handler routine is saved in EPC Next instruction Overflow ra ! EPC; jr ra Invalid instruction ra ! EPC; jr ra System Call ra ! EPC; jr ra The Exception Handler determines the cause of the exception by looking at the exception code bits. Then it jumps to the appropriate exception handling routine. -

Pearce School of Engineering and Computer Science Victoria University of Wellington Software Correctness RECOMMENDATIONS To Builders and Users of Software Make the most of effective software development technologies and formal methods. A variety of modern technologies — in particular, safe programming languages, static analysis, and formal methods — are likely to reduce the cost and difficulty of producing dependable software.

A Customizable, Front-End Retargetablesource Code Analysis
GENOA - A Customizable, front-end retargetable Source Code Analysis Framework Premkumar T. Devanbu [email protected] Dept. Of Computer Science, University of California, Davis, CA 95616 Code Analysis tools provide support for such software engineering tasks as program understanding, software metrics, testing and re-engineering. In this paper we describe genoa, the framework underlying application generators such as Aria [Devanbu et al. 1996] and gen++ [?] which have been used to generate a wide range of practical code analysis tools. This experience illustrates front-end retargetability of genoa; we describe the features of the genoa framework that allow it to be used with dierent front ends. While permitting arbitrary parse tree computations, the genoa specication language has special, compact iteration operators that are tuned for expressing simple, polynomial time analysis programs; in fact, there is a useful sublanguage of the genoa language that can express precisely all (and only) polynomial time (PTIME) analysis programs on parse-trees. Thus, we argue that the genoa language is a simple and convenient vehicle for implementing a range of analysis tools. We also argue that the “front-end reuse” approach of GENOA oers an important advantage for tools aimed at large software projects: the reuse of complex, expensive build procedures to run generated tools over large source bases. In this paper, we describe the genoa framework and our experiences with it.

A History of C++: 1979− 1991
A History of C++: 1979−1991 Bjarne Stroustrup AT&T Bell Laboratories Murray Hill, New Jersey 07974 ABSTRACT This paper outlines the history of the C++ programming language. The emphasis is on the ideas, constraints, and people that shaped the language, rather than the minutiae of language features. Key design decisions relating to language features are discussed, but the focus is on the overall design goals and practical constraints. The evolution of C++ is traced from C with Classes to the current ANSI and ISO standards work and the explosion of use, interest, commercial activity, compilers, tools, environments, and libraries. 1 Introduction C++ was designed to provide Simula’s facilities for program organization together with C’s effi- ciency and flexibility for systems programming. It was intended to deliver that to real projects within half a year of the idea. It succeeded. At the time, I realized neither the modesty nor the preposterousness of that goal. The goal was modest in that it did not involve innovation, and preposterous in both its time scale and its Draco- nian demands on efficiency and flexibility. While a modest amount of innovation did emerge over the years, efficiency and flexibility have been maintained without compromise. While the goals for C++ have been refined, elaborated, and made more explicit over the years, C++ as used today directly reflects its original aims. This paper is organized in roughly chronological order: §2 C with Classes: 1979– 1983. This section describes the fundamental design decisions for C++ as they were made for C++’s immediate predecessor. §3 From C with Classes to C++: 1982– 1985. -
