The GNU Compiler Collection (GCC) is an open source and free toolchain, enabling straightforward development on the Arm architecture.

The GNU toolchain is enabled with the latest Arm architecture and CPU feature support to give the best performance with a frictionless development experience on Arm. It is available as both a cross-toolchain for the embedded use-case and as a native toolchain in Linux distribution for server-class applications. Arm is committed to maintaining the quality of the GNU toolchain to create a world-class optimizing compiler targeting Arm.


Open source and free

GNU toolchain users have the freedom to do what they wish with their software. It is free of charge and free from restriction to use. In practice, this means that users are free to run programs for any purpose, study how programs work and change them, redistribute copies, and redistribute modified versions.

Hardware compatible

The latest Arm hardware and architectural features are enabled in the GNU toolchain even before hardware availability. That enables code exploration before hardware launch, and starting software development instantly once new hardware has become available.

Optimized for performance

The GNU toolchain for Arm Linux is optimized for performance on the Arm Cortex-A and Arm Neoverse CPU families. Powering more and more servers, Arm cores already run extremely efficiently. Leveraging GCC optimizations can significantly improve the performance of your custom user-space software.
