This is 2016.03 release 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. Eclipse IDE for GNU Toolchain for ARC Processors Documentation can be found on the GNU IDE wiki .

Toolchain and IDE Components Versions

  • Binutils v2.26+ (upstream commit id 202ac19 with additional ARC patches)
  • GCC v4.8.5
  • GDB 7.10
  • newlib v2.3
  • uclibc (upstream commit 94340ce with backported patches from uClibc-ng)
  • Eclipse Mars (4.5.1) with CDT 8.8.0
  • OpenOCD 0.9+ upstream commit 30203b3d8b, with ARC support.

This release of GNU toolchain and IDE is supported by CGEN IPlib (TCF
generator) version 1.0.53.

New Features and Enhancements

  • Binutils
    • Binutils implementation for ARC has been rewritten from the ground up for better maintainability, stability and
      functionality. The new implementation is based on upstream release 2.26.
  • GCC
    • New values for -mcpu option and new set of multilib libraries built for
      those processor configurations.
    • Support for text values of -mmpy-option, same as in hardware IP
      libraries.
    • Fixed runtime issues on 32-bit hosts.
  • Eclipse IDE
    • Support for new GCC -mcpu option values.
    • If TCF is used, options in GUI are now synchronized with it.
    • it is now possible to select current working directory when using nSIM.
  • OpenOCD
    • Added a separate configuration file for ARC EM Starter Kit v2.2, which
      requires a reduced JTAG Frequency of 5 MHz, compared to 7.5 MHz value used for versions 2.0 and 2.1.
    • NOTE: A new openOCD driver is required for Windows in this release. Please update using instructions found here
  • Toolchain build scripts
    • Option --cpu now accepts different values that are supported by GCC as
      values for -mcpu option. List of supported values is dynamic and
      evaluated based on GCC configuration.
    • Support for building of native (self-hosting) Linux/uClibc toolchain (beta)
    • New option of build-all.sh script:
    • --native - specifies whether script is building native
      (self-hosting) toolchain. That affects location of header files and
      standard library archives. It is still required to pass --host
      option to specify cross-toolchain to build native toolchain.

Bugs Fixed in This Release (Summary)

  • GCC
    • There was no multilib configuration without multiplier for ARC 700, EM
      and HS processors.
  • Newlib
    • Fixed a bug in crt0.S file that was using optional ASR a,b,u6 instruction
      without checking if barrel shifter is enabled.
  • Eclipse IDE
    • Path to standard headers was calculated improperly for big-endian
      projects.
    • Fixed an inconsistency where if toolchain is present both in the PATH and
      relatively to eclipse installation, compiler plugin would use one
      toolchain from ../bin to build project, but would use toolchain from the
      PATH to get information about standard headers.
  • OpenOCD
    • OpenOCD didn't worked with HS36 in AXS103.
  • Toolchain build scripts
    • XML files for Ashling Opella-XD GDBserver were broken for Windows systems.
    • Memory maps for AXS10x boards were broken - there was a link error when
      using them.
