I'm happy to update GNU tools for ARC cores to the most recent arc-2015.06 release. This release brings following major improvements: * GCC: source update to v4.8.4 * GCC: C ABI compatibility between MetaWare and GNU toolchains * uClibc: support for thread local storage and Native Pthread Library (NPTL) * GDB: updated to version 7.9.1 Also a lot of fixes and improvements has been done, please refer to https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/releases/tag/arc-2015.06 for more details.
