True, but if OpenOCD is to be used in embedded devices, there are things you can do to make the speed and memory footprint more palatable. You almost certainly want to disable RTTI (unless there is a very good reason to keep it), and you may want to think about eliminating or at least heavily restricting the use of exceptions, because they can have a real (>1%) performance impact, especially within a try/catch block because of the stack unwinding semantics. Otherwise, C++ is fine these days on embedded devices; even the STL tends to perform fairly well, though that does depend on the C++ library. - Dave ------------------------------------------------------------------------------ Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.
