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-R4, Cortex-R5, Cortex-M0, Cortex-M3, Cortex-M4, and Cortex-M0+. 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.
