Download or read book Auxiliary Selection in Italo Romance written by Irene Amato and published by John Benjamins Publishing Company. This book was released on 2023-11-15 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book proposes a new solution to the long-standing puzzle of auxiliary selection in Romance languages, in particular Italian. The following questions are addressed: why the perfect auxiliary appears in the two forms be and have within a single language, what drives this distribution, and how cross-linguistic data can be accounted for. The solution to these issues consists of an Agreebased analysis that accounts for auxiliary selection in root clauses and restructuring in Standard Italian and in Italo-Romance varieties, which is also compatible with participle agreement. By answering these questions, the book also touches upon more theoretical and foundational problems, such as the distribution of labor between syntax, morphology and the lexicon, and the conditions on the operation Agree (in particular, multiple probing, locality, and minimality). This work contributes to the discussion in the fields of formal morpho-syntax, theoretical linguistics, and Romance linguistics.

Download or read book Linux Kernel Debugging written by Kaiwan N. Billimoria and published by Packt Publishing Ltd. This book was released on 2022-08-05 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effectively debug kernel modules, device drivers, and the kernel itself by gaining a solid understanding of powerful open source tools and advanced kernel debugging techniques Key Features Fully understand how to use a variety of kernel and module debugging tools and techniques using examples Learn to expertly interpret a kernel Oops and identify underlying defect(s) Use easy-to-look up tables and clear explanations of kernel-level defects to make this complex topic easy Book DescriptionThe Linux kernel is at the very core of arguably the world’s best production-quality OS. Debugging it, though, can be a complex endeavor. Linux Kernel Debugging is a comprehensive guide to learning all about advanced kernel debugging. This book covers many areas in-depth, such as instrumentation-based debugging techniques (printk and the dynamic debug framework), and shows you how to use Kprobes. Memory-related bugs tend to be a nightmare – two chapters are packed with tools and techniques devoted to debugging them. When the kernel gifts you an Oops, how exactly do you interpret it to be able to debug the underlying issue? We’ve got you covered. Concurrency tends to be an inherently complex topic, so a chapter on lock debugging will help you to learn precisely what data races are, including using KCSAN to detect them. Some thorny issues, both debug- and performance-wise, require detailed kernel-level tracing; you’ll learn to wield the impressive power of Ftrace and its frontends. You’ll also discover how to handle kernel lockups, hangs, and the dreaded kernel panic, as well as leverage the venerable GDB tool within the kernel (KGDB), along with much more. By the end of this book, you will have at your disposal a wide range of powerful kernel debugging tools and techniques, along with a keen sense of when to use which.What you will learn Explore instrumentation-based printk along with the powerful dynamic debug framework Use static and dynamic Kprobes to trap into kernel/module functions Catch kernel memory defects with KASAN, UBSAN, SLUB debug, and kmemleak Interpret an Oops in depth and precisely identify it s source location Understand data races and use KCSAN to catch evasive concurrency defects Leverage Ftrace and trace-cmd to trace the kernel flow in great detail Write a custom kernel panic handler and detect kernel lockups and hangs Use KGDB to single-step and debug kernel/module source code Who this book is for This book is for Linux kernel developers, module/driver authors, and testers interested in debugging and enhancing their Linux systems at the level of the kernel. System administrators who want to understand and debug the internal infrastructure of their Linux kernels will also find this book useful. A good grasp on C programming and the Linux command line is necessary. Some experience with kernel (module) development will help you follow along.

Download or read book Explorations of Phase Theory Features and Arguments written by Kleanthes K. Grohmann and published by Walter de Gruyter. This book was released on 2009-02-26 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first volume dedicated to the study of formal features and the expression of arguments within Phase Theory, the latest model of syntactic theorizing within the Minimalist Program. The collection addresses the nature of formal features and their role in the syntactic computation as well as checking mechanisms and configurations. It also investigates theoretical issues underlying the nature of syntactic arguments and their licensing (argument structure at large) and specific grammatical operations involving arguments (abstract and morphological case, empty elements, passivization, negation, and aspect). The chapters presented in this volume provide case studies from several, typologically unrelated languages. Apart from novel analyses of new as well as well-known facts, the contributions also provide interesting aspects of and challenges for Phase Theory in general, by critically exploring a number of theoretical extensions, proposing new syntactic mechanisms, and sharpening our tools for linguistic analysis.

Download or read book The Lexicon Syntax Interface written by Pritha Chandra and published by John Benjamins Publishing Company. This book was released on 2014-03-15 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present collection offers fresh perspectives on the lexicon-syntax interface, drawing on novel data from South Asian languages like Bangla, Hindi-Urdu, Kashmiri, Kannada, Malayalam, Manipuri, Punjabi, and Telugu. It covers different phenomena like adjectives, nominal phrases, ditransitives, light verbs, middles, passives, causatives, agreement, and pronominal clitics, while trying to settle the theoretical tensions underlying the interaction of the lexicon with the narrow syntactic component. All the chapters critically survey previous analyses in detail, suggesting how these may or may not be extended to South Asian languages. Novel explanations are proposed, which handle not only the novel data presented here, but also pave alternative ways to look at issues of minimalist architecture.
