ARM is now part of the Eclipse foundation. The new plugin allows you to target development for ARM based targets. This means Eclipse can be used for all of those Palm and Game Boy devices.
The RealView Eclipse Plug-in enables developers to use Eclipse as a project manager to create, build, debug, and manage C and C++ projects for ARM targets. The plug-in provides project stationery to simplify the creation of ARM, Thumb® and ARM/Thumb architecture-based projects, and provides comprehensive configuration panels to specify options for the RealView Development Suite. The screenshot below shows an Eclipse project building an application for Embedded Linux with the compilation tools in RealView Development Suite.
