This is release of 2022.09 version of the GNU Toolchain for DesignWare ARC 600, ARC 700, EM, HS3x/4x, HS5x & HS6x processors. Most notably, this is the first release of ARC GNU toolchain with support of both 32- (ARC HS5x) & 64-bit (ARC HS6x) versions of ARCv3 processors.

GNU Documentation can be found online here https://foss-for-synopsys-dwc-arc-processors.github.io/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 2.38 with ARC patches
  • GCC 12.2 with ARC patches
  • GDB 12.1 with ARC patches
  • newlib 3.2.0 with ARC patches
  • uClibc-ng v1.0.42
  • glibc 2.34

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

New Features and Enhancements

Fixes and improvements in the final release compared to Release Candidate 3

  1. Fixed missing optimized functions in Newlib for ARCv3 processors (#512)

Fixes and improvements in the Release Candidate 3 compared to Release Candidate 2

  1. Fixed 8 Kb MMU page use in uClibc Linux toolchain for ARC HS58 processors (#511)

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

  1. Fixed "GDB for Windows does not work correctly in Eclipse plugin" (#501).
  2. Fixed "undefined reference to _kill/_kill_r & _getpid/_getpid_r" when building bare-metal applications (#502).
  3. Added support of 64-bit atomic instructions (llockd & scondd) for 32-bit ARCv3 ARC HS5x processors (#505)

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
