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.
