As part of its ongoing commitment to maintaining and enhancing GCC compiler support for the ARM architecture, ARM is maintaining a GNU toolchain with a GCC source branch targeted at Embedded ARM Processors, namely Cortex-R/Cortex-M processor families, covering Cortex-M0, Cortex-M3, Cortex-M4, Cortex-M0+, Cortex-M7, ARMv8-M Baseline and mainline, Cortex-R4, Cortex-R5, Cortex-R7 and Cortex-R8. As part of this, ARM releases at regular intervals pre-built and tested binaries from the ARM embedded branch. The improvements are freely available for integration into 3rd party toolchains, and for direct download by end-users.

ARM employees are maintaining this project. Contributions to this project are be done via GCC [1] trunk, binutils-gdb [2] master branch and newlib [3] master branch. This launchpad project is for communication and bug reporting. Downloads are made from developer.arm.com website [4] and no code change is done in Launchpad project.
