This is the first release candidate of 2020.03 version of the GNU Toolchain for DesignWare ARC Processors.

GNU Documentation PDF files can be found in share/doc directory of installed toolchain, as well as online at embarc.org.

A list of useful how-to instructions can also be found on the GNU Toolchain for DesignWare ARC Processors Documentation wiki.

Toolchain and IDE Components Versions

  • Binutils 2.34 with ARC patches
  • GCC 9.3 with ARC patches
  • GDB 10-prerelease with ARC patches
  • newlib 3.2.0 with ARC patches
  • uClibc-ng v1.0.31
  • glibc 2.30 with ARC patches
  • Eclipse 2020-03 4.15.0 with CDT 9.11.0
  • 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 and later.

New Features and Enhancements

  • Binary distribution

    • Supported host operating systems: Windows 10 64-bit, Ubuntu 16.04.x, 18.04.x, CentOS/RHEL 7.x
    • No longer compatible with CentOS/RHEL 6.x due to GDB 8.3 and newer requirement for C++11 support in the compiler.
      Still it's perfectly possible to build Elf32 & uClibc toolchains without GDB on CentOS/RHEL 6.x.

  • Toolchain Build Scripts

    • Documentation update

  • GCC

  • GDB

    • Binutils & GDB now use the same code base however for simplicity & compatibility of build-system we still keep separate branches for each component
    • GDB code is based on what will become v10.0

  • Binutils

  • glibc

    • No changes since 2019.09 release

  • Eclipse plugins

    • Eclipse 2020-03 is used as a base
    • Bug fixes

Known issues

  1. CenOS 6.x hosts are not supported any longer for both running prebuilt tools as well as for building tools, see #202.

  2. GDB compilation may intermittently fail due to unwanted regenerating intl/plural.c, see #212.

  3. Ashling Opella-XD drivers of version 1.2.6 and above couldn't be used with ARC GNU IDE (Jira P10019563-38842).

  4. Newlib's libgloss doesn't support RF16 configuration of ARC cores when building for nSIM, see #231.

  5. GDB compilation fails on macOS hosts, see #245 and upstream bug-report https://sourceware.org/bugzilla/show_bug.cgi?id=25731. Thus we're not providing pre-built binaries fror macOS in RC1, will be added in RC2.

  6. Linkage of some application for ARC EM fails, see #259.

Please report any problems by filing an Issue in GitHub here.

Note: The toolchain is only supported for 64-bit versions of Linux hosts. 32-bit Linux hosts are not supported.
