The Lcc 4.X Code-Generation Interface
The lcc 4.x Code-Generation Interface Christopher W. Fraser and David R. Hanson Microsoft Research [email protected] [email protected] July 2001 Technical Report MSR-TR-2001-64 Abstract Lcc is a widely used compiler for Standard C described in A Retargetable C Compiler: Design and Implementation. This report details the lcc 4.x code- generation interface, which defines the interaction between the target- independent front end and the target-dependent back ends. This interface differs from the interface described in Chap. 5 of A Retargetable C Com- piler. Additional infomation about lcc is available at http://www.cs.princ- eton.edu/software/lcc/. Microsoft Research Microsoft Corporation One Microsoft Way Redmond, WA 98052 http://www.research.microsoft.com/ The lcc 4.x Code-Generation Interface 1. Introduction Lcc is a widely used compiler for Standard C described in A Retargetable C Compiler [1]. Version 4.x is the current release of lcc, and it uses a different code-generation interface than the inter- face described in Chap. 5 of Reference 1. This report details the 4.x interface. Lcc distributions are available at http://www.cs.princeton.edu/software/lcc/ along with installation instruc- tions [2]. The code generation interface specifies the interaction between lcc’s target-independent front end and target-dependent back ends. The interface consists of a few shared data structures, a 33-operator language, which encodes the executable code from a source program in directed acyclic graphs, or dags, and 18 functions, that manipulate or modify dags and other shared data structures. On most targets, implementations of many of these functions are very simple. -

Gnu Compiler Collection Backend Port for the Integral Parallel Architecture
U.P.B. Sci. Bull., Series C, Vol. 74, Iss. 3, 2012 ISSN 1454-234x GNU COMPILER COLLECTION BACKEND PORT FOR THE INTEGRAL PARALLEL ARCHITECTURE Radu HOBINCU1, Valeriu CODREANU2, Lucian PETRICĂ3 Lucrarea de față prezintă procesul de portare a compilatorului GCC oferit de către Free Software Foundation pentru arhitectura hibridă Integral Parallel Architecture, constituită dintr-un controller multithreading și o mașina vectorială SIMD. Este bine cunoscut faptul că motivul principal pentru care mașinile hibride ca și cele vectoriale sunt dificil de utilizat eficient, este programabilitatea. În această lucrare vom demonstra că folosind un compilator open-source și facilitățile de care acesta dispune, putem ușura procesul de dezvoltare software pentru aplicații complexe. This paper presents the process of porting the GCC compiler offered by the Free Software Foundation, for the hybrid Integral Parallel Architecture composed of an interleaved multithreading controller and a vectorial SIMD machine. It is well known that the main reason for which hybrid and vectorial machines are difficult to use efficiently, is programmability. In this paper we well show that by using an open-source compiler and the features it provides, we can ease the software developing process for complex applications. Keywords: integral parallel architecture, multithreading, interleaved multithreading, bubble-free embedded architecture for multithreading, compiler, GCC, backend port 1. Introduction The development of hardware technology in the last decades has required the programmers to offer support for the new features and performances of the last generation processors. This support comes as more complex compilers that have to use the machines' capabilities at their best, and more complex operating systems that need to meet the users' demand for speed, flexibility and accessibility. -

Porting the QEMU Virtualization Software to MINIX 3
Porting the QEMU virtualization software to MINIX 3 Master's thesis in Computer Science Erik van der Kouwe Student number 1397273 [email protected] Vrije Universiteit Amsterdam Faculty of Sciences Department of Mathematics and Computer Science Supervised by dr. Andrew S. Tanenbaum Second reader: dr. Herbert Bos 12 August 2009 Abstract The MINIX 3 operating system aims to make computers more reliable and more secure by keeping privileged code small and simple. Unfortunately, at the moment only few major programs have been ported to MINIX. In particular, no virtualization software is available. By isolating software environments from each other, virtualization aids in software development and provides an additional way to achieve reliability and security. It is unclear whether virtualization software can run efficiently within the constraints of MINIX' microkernel design. To determine whether MINIX is capable of running virtualization software, I have ported QEMU to it. QEMU provides full system virtualization, aiming in particular at portability and speed. I find that QEMU can be ported to MINIX, but that this requires a number of changes to be made to both programs. Allowing QEMU to run mainly involves adding standardized POSIX functions that were previously missing in MINIX. These additions do not conflict with MINIX' design principles and their availability makes porting other software easier. A list of recommendations is provided that could further simplify porting software to MINIX. Besides just porting QEMU, I also investigate what performance bottlenecks it experiences on MINIX. Several areas are found where MINIX does not perform as well as Linux. The causes for these differences are investigated. -
