This is the first release candidate 2016.09 release 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 2.27+ (upstream commit decf5bd and ARC patches)
  • GCC 6.2.1 (upstream commit e061fbe and ARC patches)
  • GDB 7.12 (upstream commit 5f8cf6c and ARC patches)
  • newlib 2.4 (upstream commit e6413b0 and ARC patches)
  • uclibc-ng 1.0.17 (plus 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

  • Toolchain build scripts
    • Use GNU FTP server to download GMP, MPFR and MPC, update to latest
      versions of those libraries and download .tar.xz files of GMP and MPFR.
  • GCC
    • Major compiler upgrade from gcc 4.8.5 in previous release to gcc 6.2.1 in this release
    • Support for new version of Intel's QuarkSE microcontroller via new mcpu option "quarkse2_em"
    • Support -fstack-protector and -fstack-protector-all (uclibc toolchain only)
    • Support for profiling using gmon for elf32 toolchain (newlib)
    • Remove support for -mabi option. Now GCC always generates function calls
      compatible with MetaWare compiler.
    • Avoid unnecessary dependency of libgcc on newlib.
  • Binutils
    • Revamped implementation of Position Independent Code (PIC) and Position Independent Executable (PIE)
      for much improved and robust support.
    • Linux security feature: All constant value global symbols which end up as dynamic relocations are now
      placed in .data.rel.ro sections and resolved by the dynamic linker and set as read-only.
  • GDB
    • Support multi-target GDB in ARC code. GDB for baremetal targets now can
      debug Linux targets as well.
  • uClibc
    • Migrated to uClibc-ng
  • OpenOCD
    • Add support for DCCM version 4.
  • CGEN
    • Removed formal dependency on CGEN repository (no longer in use).
  • IDE
    • Migrated to use DSF instead of obsolete CDT for debugging, which brings
      in multiple usability enhancements.
    • Updated to latest version of TerminalView plugins.
    • Detect if projects has been created with an older version of IDE and show
      user a warning that there could be compatibility issues.
    • Removed support for -mabi option that has been removed from ARC GCC.
