It seems to be little known that modern C++ is capable of producing a rather efficient code, often better than hand-crafted C, provided it is used by competent C++ developers. Even RTTI and exceptions are not an issue performance-wise because you can easily avoid using them specifically on the hot pathes (e.g. exceptions should be used only for really exceptional situations, and there a bit of performance hit of stack unwinding doesn't matter, and virtual functions are not needed that often either (though Java devs would disagree ;) )). BTW, GCC "switched" to C++ recently, and LLVM was using it right from the beginning. It seems to be assumed by most people here that C++ benefits lie mostly in its OOP model, inheritance and such. Andrei Alexandrescu would disagree [0]. In fact the language designers are concentrating currently on compile-time efficient type-safe generic programming. The template language evolved into a pure-functional Turing-complete compile-time language. One of the popular examples is the Boost::Spirit library which compile-time generates very efficient parsers from an "almost EBNF" description right from the C++ sources [1]. So the main benefits of using C++11 would be: compile-time type-safety, efficient compile-time meta-programming. And of course, cleaner, safer, more maintainable code as the result. The downside would be that C++11 and its "advanced" template facilities are harder to learn and many people would like to use it like a dialect of Java (preferring inheritance over composition, avoiding template programming etc, which would indeed be highly inefficient and inelegant). To get a taste of modern C++ you can watch this introductory video by one of the core designers, Herb Sutter: (Not Your Father’s) C++ [2]. One step that might bring OpenOCD closer to the modern programming practicies would be to make it buildable with g++ without any real redesign (similar to what GCC developers did with their compiler).
