MSP430 IAR C/C++ Compiler reference guide - Rice University

Overview●●●Runtime type informationNew cast syntax (the operators dynamic_cast, static_cast,reinterpret_cast, and const_cast)Namespaces● The mutable attribute.The exclusion of these language features makes the runtime library significantly moreefficient. The Embedded C++ library furthermore differs from the full C++ library inthat:●●The standard template library (STL) is excludedStreams, strings, and complex numbers are supported without the use of templates● Library features which relate to exception handling and runtime type information(the headers except, stdexcept, and typeinfo) are excluded.Note: The library is not in the std namespace, because Embedded C++ does notsupport namespaces.EXTENDED EMBEDDED C++IAR Systems’ Extended EC++ is a slightly larger subset of C++ which adds thefollowing features to the standard EC++:● Full template support● Namespace support● The mutable attribute● The cast operators static_cast, const_cast, and reinterpret_cast.All these added features conform to the C++ standard.To support Extended EC++, this product includes a version of the standard templatelibrary (STL), in other words, the C++ standard chapters utilities, containers, iterators,algorithms, and some numerics. This STL has been tailored for use with the ExtendedEC++ language, which means that there are no exceptions, no multiple inheritance, andno support for runtime type information (rtti). Moreover, the library is not in the stdnamespace.Note: A module compiled with Extended EC++ enabled is fully link-compatible witha module compiled without Extended EC++ enabled.ENABLING C++ SUPPORTIn the MSP430 IAR C/C++ Compiler, the default language is C. To be able to compilefiles written in Embedded C++, you must use the --ec++ compiler option. See --ec++,page 151. You must also use the IAR DLIB runtime library.102MSP430 IAR C/C++ CompilerReference Guide
