## Toolchains

See [ARM Family](https://github.com/RIOT-OS/RIOT/wiki/Family:-ARM), and
[Eistec wiki - Installing-toolchain (GCC)](https://github.com/eistec/mulle/wiki/Installing-toolchain-%28GCC%29)

Working:
* [gcc-arm-embedded](https://github.com/RIOT-OS/RIOT/wiki/Family:-ARM#gcc-arm-embedded-toolchain)
* Clang 3.4 - Clang 4.0 - Install procedure not documented but pretty
straightforward, Makefiles and build system is fully functional with Clang.
