The IAR Embedded Workbench integrates the IAR C/C++ compiler, assembler, linker, librarian, text editor, project manager and C-SPY debugger into one integrated development environment (IDE).

IAR advertises this as an EC++ (Embedded C++) compiler. However, the latest version adds many important C++ features such as templates, namespaces, mutable, static cast, reinterpret cast, and const cast. It is becoming more of a "real" C++ compiler with each release.

Our experience with IAR is that it is an easy to use compiler with few problems. We resell both the Professional and the Base Level Edition (EWARM-BL). The only difference is that EWARM-BL does not include the C-SPY Simulator, JTAG support and RTOS plug-in.
