Pre-built GNU toolchain from ARM Cortex-M & Cortex-R processors (Cortex-
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  trunk, binutils-gdb  master branch and newlib  master branch. This launchpad project is for communication and bug reporting. Downloads are made from developer.arm.com website  and no code change is done in Launchpad project.
For Ubuntu 12.04/14.
