kvx: add support for kvx arch to uClibc-ng
This commit adds support for Kalray VLIW family (kvx) Kalray kv3 core is embedded in Kalray Coolidge SoC. This core which is the third of the KV family has the following features: 32/64 bits execution mode 6-issue VLIW architecture 64 x 64bits general purpose registers SIMD instructions little-endian In order to build a usable toolchain, build scripts are provided at the following address: https://github.com/kalray/build-scripts. Kalray uses FOSS which is available at https://github.com/kalray This includes Linux kernel, uClibc-ng, gcc, binutils, etc. Signed-off-by: Clément Léger <cleger@kalray.eu> Signed-off-by: Guillaume Thouvenin <gthouvenin@kalray.eu> Signed-off-by: Laurent Thevenoux <lthevenoux@kalray.eu> Signed-off-by: Marc Poulhies <mpoulhies@kalray.eu> Signed-off-by: Marius Gligor <mgligor@kalray.eu> Signed-off-by: Yann Sionneau <ysionneau@kalray.eu>
