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.

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.

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.

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

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

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. Binutils bug #431 causing pop-up with warning when using ar utility on Windows host. See #431 (comment) for work-around.

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

GNU Toolchain for ARC64 Processors, 2021.09

This is release of the 2021.09 version of the GNU Toolchain for 64-bit DesignWare ARC HS6x Processors.

Currently, only 2 toolchain flavours are available in a pre-built form for ARC64: little-endian bare metal & glibc Linux toolchains.

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