Granite Bay, Calif. - At ESC San Jose, CodeSourcery announced the release of Sourcery G++ for ARM, ColdFire, IA32, MIPS, Power Architecture, Stellaris and SuperH processors. The latest release features enhancements that boost application performance and make it easier to get started with GNU/Linux application development.
Improved Thumb-2 code generation in the spring 2010 release yields better performance on the ARM Cortex-A family, with a 25% speed-up on the CoreMark benchmark compared to the spring 2009 release as measured on a Texas Instruments OMAP3530 Cortex-A8 processor. The new release introduces support for the microMIPS instruction set architecture and faster software floating-point emulation routines for MIPS bare-metal targets. Sourcery G++ for Power features more efficient code generation for Freescale’s QorIQ processor and optimized core library routines for Freescale’s E500 processor for Linux and bare-metal development
The new version of Sourcery G++ makes it simpler to use the Remote System Explorer (RSE) to debug Linux applications with GDB Server, includes enhanced support for flash programming via Segger J-Link, and features an update to the GNU Debugger (GDB) version 7.0.50. Other improvements to the Sourcery G++ Debug Sprite make it easier to debug in bare-metal and RTOS environments.
“Our team is working hard to make it easier to develop embedded applications—and to make those applications faster and smaller,” said Mark Mitchell, Chief Sourcerer of CodeSourcery. “By working with the world’s leading silicon companies and by integrating our own technology with the best open-source tools, CodeSourcery is able to offer affordable, high-quality C and C++ development tools for a wide range of embedded platforms, including ARM, ColdFire, IA32, MIPS, Power and SuperH."
Sourcery G++ contains enhanced versions of popular open-source tools, including an integrated development environment based on Eclipse and the Eclipse C/C++ Development Tools, C/C++ compilers, an assembler and linker, runtime libraries, and a source- and assembly-level debugger. Sourcery G++ runs on GNU/Linux or Microsoft Windows hosts (including Windows 7) and supports bare metal, RTOS, uClinux, GNU/Linux or Windows target systems. Sourcery G++ is available in Professional, Standard and Personal Editions.
