This is release 2015.06 of the GNU Toolchain for DesignWare ARC Processors.

A list of useful how-to instructions can be found on the GNU Toolchain for DesignWare ARC Processors Documentation wiki. GNU Documentation PDF files can be found in share/doc directory of installed toolchain.

Toolchain Components

  • GCC v4.8.4
  • Binutils v2.23
  • newlib v2.0
  • uclibc (upstream HEAD at the moment of release)
  • GDB 7.9.1

A complete Eclipse IDE for GNU Toolchain for DesignWare ARC Processors can also be downloaded here

New Features and Enhancements

  • 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) in uClibc / linux toolchain
  • GDB: updated to version 7.9.1
  • GDB/GDBserver/openOCD: Add support for standard xml target description file
  • openOCD: Allow users to configure registers without recompiling
