Important

EM Starter Kit and Ashling Opella-XD probe are EOL (End of Life) and they are no longer supported. Refer the old documentation site for guides related to EM Starter Kit and Ashling Opella-XD for old releases. Corresponding pages on the official documentation site for recent releases still exist but they may be not applicable for the recent releases.

Toolchain and IDE Components Versions

  • GCC 14.2 with ARC patches
  • Binutils 2.43 with ARC patches
  • GDB 15.1 with ARC patches
  • Newlib 4.4.0 with ARC patches
  • uClibc-ng v1.0.49 with ARC patches
  • glibc 2.40 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

Binary distribution

  • Supported host operating systems: Windows 11 64-bit, Ubuntu 22.04, RHEL/AlmaLinux 8.x
  • Prebuilt bare-metal toolchains for 64-bit Windows & Linux hosts, see table with references and list of artifacts below.

Toolchain Components

For this release binary distributions of ARC GNU tools for all supported processor families (both ARC Classic and ARC-V) are produced from the same sources of corresponding tools.

There are no major changes for ARC Classic targets except ARC-specific improvements and fixes for ARCompact, ARCv2 and ARCv3 ISA processors on top of the upstream releases. All components are updated on top of upstream releases.

There are a few major changes for ARC-V targets besides updates to the latests versions:

  1. Added full support of tuning instructions scheduling for RMX-100, RMX-500 and RHX-100.
  2. Add initial support of RVV extension for ARC-V RPX processors in the binary distribution of ARC GNU toolchain.
  3. Prebuilt standard libraries for base RMX-100, RMX-500 and RHX-100 profiles are included. Refer Understanding ARC-V Configurations page for details.

Here is a list of GitHub issues addressed in this release: GitHub issues for 2024.12. 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.

Known issues

ARC Classic

  1. Newlib's libgloss doesn't support RF16 configuration of ARC cores when building for nSIM with -specs=nsim.specs, see #231. Use -specs=hl.specs instead for RF 16 configurations.

  2. Non-multilib toolchain doesn't contain libgloss libraries for nSIM and development boards, see #262.

  3. 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.

  4. Eclipse IDE for ARCompact does not support selecting -specs= options in project's configuration menu. Consider passing this options (e.g., -specs=nsim.specs for nSIM) in "ARC GNU Linker" field of projects configuration dialog (C/C++ Build -> Settings -> Top Settings -> ARC GNU Linker).

ARC-V

  1. Some complex combinations of -march= and -mabi= options may lead to unpredictable errors during compilation. Such issues are related to general support of RISC-V extensions in GCC. Refer #610 for details.

  2. The size-optimized Newlib Nano configuration (used when -specs=nano.specs is passed to GCC) does not support printf() for float and double by default. Nano printf() is size-optimized and does not include support of float and double. If you need that feature, pass -u _printf_float to GCC when you compile your applications. This option picks up support of float and double for size optimized printf() on demand.

  3. There is an issue in GCC that prevents matching -march configurations like rv32imc and rv32im_zca as compatible and interchangeable. Refer #653 for details.

  4. Using selective scheduler with a specific set of options may lead to incorrect code generation. Refer Bug 118153 for details.

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

There are 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. #630: A temporary patch applied to fix an incorrect behavior of __builtin_mul_overflow function.
  2. #633: Resolved an issue when FPU is not enabled by default in Newlib for ARC-V targets with f or d extensions.

  2. GCC 14 generates incorrect include directories if it's configured with --with-sysroot=... and --with-native-system-header-dir=... options. This is a valid set of options for building GCC, however since GCC that leads to including invalid paths to a includes search list when -save-temps is used while building binaries. This issue is not critical and is going to be addressed later. See #628.

  3. The size-optimized Newlib Nano configuration (used when -specs=nano.specs is passed to GCC) does not support printf() for float and double by default.

GNU Toolchain for ARC Processors, arc-2023.12-release

This is release of 2023.12 version of the GNU Toolchain for Synopsys ARC-V Processor IP.
This release introduces support for ARC-V RMX and RHX processors series based on RISC-V instruction set architecture.

More information about these processors can be found on Synopsys website here Power-Efficient RISC-V Processors for Embedded Applications and here Maximum Performance Efficiency for Real-time Applications.

arc-v-hero-aem

Important

This release of ARC GNU tools doesn't include prebuilt toolchains for ARC Classic processor families. In the future we plan to support all current ARC processors in the same release of ARC GNU tools. Users of ARC600, ARC700, ARC EM, ARCv2 HS (HS3x & HS4x) and ARCv3 HS (HS5x & HS6x) should keep using ARC GNU Tools 2023.09 (latest version).

New Features and Enhancements

Support for RISC-V based ARC-V RMX and RHX processors series

  • In this release the following RISC-V extensions are supported: Zba, Zbb, Zbs, Zdinx, Zfinx, Zicbom, Zicbop, Zicboz.
  • Support for ARC-V RMX & RHX processors:
    • Instruction scheduling tuning for ARC-V RMX-100 (-mtune=rmx100) & RMX-500 (-mtune=rmx500) processors
    • Instruction fusion for ARC-V RHX series (-mtune=rhx)
    • Implementation of the code size reduction extensions Zcb & Zcmp
  • As this is the first release of prebuilt GNU tools with ARC-V support, some functionality may have issues, some processor features may not yet be fully supported, and performance may be lower that expected performance of the final product.

Binary distribution

  • Supported host operating systems: Windows 10 64-bit, Ubuntu 18.04.x, 20.04.x, CentOS/RHEL 7.x
  • Prebuilt bare-metal toolchains for 64-bit Windows & Linux hosts, see table with references and list of artifacts below.

Toolchain Components

  • GCC 13.2 with ARC patches

  • Binutils pre-2.41 with ARC patches

    • Upstream sources of pre-v2.41, see release announcement.
    • Added code size reduction Zcb & Zcmp extensions.

  • GDB 12.1 with ARC patches

  • Newlib 4.3.0 with ARC patches

    • Updated sources of 4.3.0 release, see release announcement.
    • Improved start-up code to initialize GP (global pointer), SP (stack pointer), clear .bss section etc.
    • Provided custom linker script for use with fast on-chip memories (DCCM & ICCM).

Known issues

  • There are no known issues so far for that release.

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.

GNU Toolchain for ARC Processors, arc-2023.09-rc2 Pre-release
Pre-release

This is the second release candidate 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/documentation/2023.09/.

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 inthe corresponding bug-tracking system.

Fixes and improvements in the final release 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.
