Written for any programmer who works with compiled code, Linkers and Loaders surveys today's hardware platforms with a tour of how code is linked and executed on IBM mainframes, Unix, and Windows. This handy title fills a valuable niche for anyone who wants to understand how programs are built and run on today's computing systems.It's the cross-platform perspective that distinguishes this book. The author's wide-ranging perspective on IBM 370 mainframes, RISC platforms like the SUN SPARC and, of course, Microsoft Windows makes this book a commendable reference on the internals of linkers and program execution in each environment. There's also a digestible guide to the computer architecture (including registers, instruction formats, and memory addressing) for each platform. (Unix programmers will be pleased that the book has more information on non-Windows platforms than on Windows itself.) For C++ programmers, this text gives you a glimpse into the internals of such language features as macros, templates, and name mangling, and how linkers deal with them at build time.The book closes with useful material on static libraries and dynamic linking, plus a short tour of Java and its class loader (which can resolve classes on the fly as they are downloaded over the Internet). Short exercises are provided for each chapter, making this a useful resource for both classroom and self-study on what is an often overlooked topic.
