This is the first release candidate for release 2017.03 of the GNU Toolchain for DesignWare ARC Processors.

A list of useful how-to instructions can be found on the GNU Toolchain for DesignWare ARC Processors Documentation wiki. GNU Documentation PDF files can be found in share/doc directory of installed toolchain. Eclipse IDE for GNU Toolchain for ARC Processors Documentation can be found on the GNU IDE wiki .

Toolchain and IDE Components Versions

  • Binutils 2.28 with additonal ARC patches
  • GCC 6.3.0 with additional ARC patches
  • GDB 7.12 (upstream commit 5f8cf6c) with ARC patches
  • newlib 2.4 (upstream commit e6413b0) with ARC patches
  • uclibc-ng 1.0.17 with few ARC patches
  • Eclipse Mars (4.5.1) with CDT 8.8.0
  • OpenOCD 0.9+ upstream commit 30203b3d8b, with ARC support.

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

New Features and Enhancements

  • Prebuilt Binaries
    • ARC HS toolchain now includes sysroot for -mcpu=hs38_linux.
  • Toolchain build scripts
    • Added support for building the bare metal GNU Toolchain (elf32) for Mac OS X hosts
    • Removed obsolete unsupported scripts.
    • Toolchain documentation from wiki is now also built from Sphinx and available online.
    • Added tcftool binary to toolchain for Windows and x86 Linux hosts.
  • GCC
    • Updated to GCC 6.3.0
    • Added support for JLI instruction for ARCv2 ISA Processors
    • Added support for Secureshield technology on supported ARC EM Processors (SFLAG, SJLI instructions, new "secure_call" attribute)
    • Experimental support for reduced register file for ARC EM Processors via new -mRF16 option and -mcpu=em_mini choice. - **Note: this is preliminary support for experimentation. This feature has been not fully verified so bugs can be expected in this area - we are planning to fully productized in the 2017.09 release.
  • Binutils
    • Updated to version 2.28
    • Improvement to stack unwinding functionality in linux/uclibc toolchain
  • OpenOCD
    • Added support for Secure MPU registers
