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

  1. Updated documentation
  2. [Jira P10019563-49796] C++ "Hello world" sample now compiles correctly
  3. [Jira P10019563-49753] tcftool was not installed

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. Full gdb debugger is installed in .../glibc_le_archs_native/debug-root/usr/bin but not in .../glibc_le_archs_native/bin, see #439
