Pre-built GNU toolchain from ARM Cortex-M & Cortex-R processors (Cortex-M0/M0+/M3/M4/M7, Cortex-R4/R5/R7).

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, Cortex-R4, Cortex-R5 and Cortex-R7. As part of this, ARM will, at regular intervals, release binaries pre-built and tested from the ARM embedded branch. The improvements will be freely available for integration into 3rd party toolchains, and for direct download by end-users.

ARM employees are maintaining this project. Contributing to this project should be via GCC trunk and binutils trunk This launchpad project is for communication and downloading. No code change is done in lp project.

For Ubuntu 10.04/12.04/13.04 32/64-bit user, PPA is available at
