This is release of 2023.09 version of the GNU Toolchain for DesignWare ARC 600, ARC 700, EM, HS3x/4x, HS5x & HS6x processors. This is a maintenance release which brings incremental improvements for major toolchain components such as GCC, Binutils & GDB for ARC processors.

GNU Documentation can be found online here https://foss-for-synopsys-dwc-arc-processors.github.io/experimental-documentation/2023.09/toolchain.

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 pre-2.41 with ARC patches
  • GCC 13.1 with ARC patches
  • GDB pre-14.1 with ARC patches
  • newlib 4.3.0 with ARC patches
  • uClibc-ng v1.0.43 with ARC patches
  • glibc 2.38 with ARC patches

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

New Features and Enhancements

Also, here is the list of GitHub issues addressed in this release: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/issues?q=is%3Aissue+milestone%3A2023.09+is%3Aclosed+
Note, though, this list only contains issues filed against ARC GNU toolchain. Bugs and enhancements made in upstream open-source projects of each toolchain component could be found in the corresponding bug-tracking system.

Fixes and improvements in the final release compared to Release Candidate 2

There're no changes in the final release compared to the release candidate 2.

Fixes and improvements in the Release Candidate 2 compared to Release Candidate 1

  1. Resolved an issue (P10019563-65093) with creating a project in ARC GNU IDE in a new workspace.
  2. OpenOCD JTAG probe could be used now with EM SDP in ARC GNU IDE.

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. [Jira P10019563-38842] Ashling Opella-XD drivers of version 1.2.6 and above to work with ARC GNU IDE required to run the Ashling GDB server separately and select "Connect to a running GDB server" in the Debug Launch.

    To run the Ashling GDB server use the following from a command prompt:

    C:\AshlingOpellaXDforARC> ash-arc-gdb-server.exe --device arc-em

    Other supported devices are arc-hs, arc-600 and arc-700.

    See section "3.2 Configuring the Ashling GDB Server" in the Ashling Opella-XD ARC User manual for more details.

  4. Newlib's libgloss doesn't support RF16 configuration of ARC cores when building for nSIM with "GNU Hostlink", see #231. But with use of "MetaWare Hostlink" RF16 configuration might be used now, see https://github.com/foss-for-synopsys-dwc-arc-processors/newlib/blob/arc-2021.03/libgloss/arc/readme-hostlink.md for more details.

  5. Non-multilib toolchain built for ARC EM doesn't contain libdw_uart.a for EMSK, see #262

  6. macOS cross-toolchains are not being distributed in this release

  7. libcrypt.so.1 is not included in the toolchain (starting from glibc 2.38 libcrypt.so.1 is not built by default and will be removed from glibc in the future), please use libcrypt implemented by external libraries such as libxcrypt instead of relying on Glibc internal implementation.

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