viswa informs us of a source for “Completely Free Open Source GCC builds for ARM MCUs and MPUs. This seems to be maintained by the official team which maintains GCC for ARM. This is useful for ARM Cortex M / Cortex R processors.”
Pre-built GNU toolchains from ARM Cortex-R & Cortex-M processors, together with source code can be found here. (Note that the reference to “launchpad” in the URL refers to the Launchpad open source suite of tools for software collaboration and not the MSP430 Launchpad hardware.)
