GNU Toolchain for ARC Processors, 2016.09

This is release 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.

GNU Toolchain for ARC Processors, 2016.09 RC1 Pre-release
Pre-release

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.

GNU Toolchain for ARC Processors, 2016.03

This is 2016.03 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 v2.26+ (upstream commit id 202ac19 with additional ARC patches)
  • GCC v4.8.5
  • GDB 7.10
  • newlib v2.3
  • uclibc (upstream commit 94340ce with backported patches from uClibc-ng)
  • 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.

New Features and Enhancements

  • Binutils
    • Binutils implementation for ARC has been rewritten from the ground up for better maintainability, stability and
      functionality. The new implementation is based on upstream release 2.26.
  • GCC
    • New values for -mcpu option and new set of multilib libraries built for
      those processor configurations.
    • Support for text values of -mmpy-option, same as in hardware IP
      libraries.
    • Fixed runtime issues on 32-bit hosts.
  • Eclipse IDE
    • Support for new GCC -mcpu option values.
    • If TCF is used, options in GUI are now synchronized with it.
    • it is now possible to select current working directory when using nSIM.
  • OpenOCD
    • Added a separate configuration file for ARC EM Starter Kit v2.2, which
      requires a reduced JTAG Frequency of 5 MHz, compared to 7.5 MHz value used for versions 2.0 and 2.1.
    • NOTE: A new openOCD driver is required for Windows in this release. Please update using instructions found here
  • Toolchain build scripts
    • Option --cpu now accepts different values that are supported by GCC as
      values for -mcpu option. List of supported values is dynamic and
      evaluated based on GCC configuration.
    • Support for building of native (self-hosting) Linux/uClibc toolchain (beta)
    • New option of build-all.sh script:
    • --native - specifies whether script is building native
      (self-hosting) toolchain. That affects location of header files and
      standard library archives. It is still required to pass --host
      option to specify cross-toolchain to build native toolchain.

Bugs Fixed in This Release (Summary)

  • GCC
    • There was no multilib configuration without multiplier for ARC 700, EM
      and HS processors.
  • Newlib
    • Fixed a bug in crt0.S file that was using optional ASR a,b,u6 instruction
      without checking if barrel shifter is enabled.
  • Eclipse IDE
    • Path to standard headers was calculated improperly for big-endian
      projects.
    • Fixed an inconsistency where if toolchain is present both in the PATH and
      relatively to eclipse installation, compiler plugin would use one
      toolchain from ../bin to build project, but would use toolchain from the
      PATH to get information about standard headers.
  • OpenOCD
    • OpenOCD didn't worked with HS36 in AXS103.
  • Toolchain build scripts
    • XML files for Ashling Opella-XD GDBserver were broken for Windows systems.
    • Memory maps for AXS10x boards were broken - there was a link error when
      using them.

GNU Toolchain for ARC Processors, 2015.12

This is 2015.12 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

  • GCC v4.8.5
  • Binutils v2.23
  • newlib v2.3
  • uclibc (upstream HEAD at the moment of release)
  • GDB 7.10
  • Eclipse Mars (4.5.1) with CDT 8.8.0
  • OpenOCD 0.9+ upstream commit 30203b3d8b, with ARC support.

New Features and Enhancements

  • GCC
    • Source update to v4.8.5
    • New preprocessor defines for processor optional features, like -mnorm, -mll64, etc.
    • Fast interrupt (FIRQ) function attribute support
    • Naked function attribute support
  • GDB
    • Updated to upstream 7.10 release.
  • Pre-built binaries
    • Baremetal toolchain now contains additional set of libc/libstdc++ binaries compiled with optimization for code size. Can be selected by passing --specs=nano.specs to gcc.
    • Standard libraries in baremetal toolchain are now stripped of debug information, except for .debug_frame section.
    • Linux toolchain for ARC HS now contains sysroot for ARC 700. It is now possible to build ARC 700 application using ARC HS toolchain, by passing an option --sysroot=$INSTALLDIR/arc-snps-linux-uclibc/sysroot-arc700 to arc-linux-gcc, where $INSTALLDIR is a path to toolchain installation folder. This is implemented for both little end big endian toolchains.
    • Toolchain binaries are linked dynamically
  • Eclipse IDE
    • Removed redundant "hostname" text field from debugger configuration when locally started gdbserver are used.
    • ARC template projects have been reorganized. They are now grouped by target ARC development system.
    • Added validation for text fields in debugger configuration.
    • TCF support to build configurations
    • Debugger configuration UI now has a full support of Synopsys ARC development systems for OpenOCD
    • Reworked template projects for Synopsys ARC development systems
    • Updated processor option in compiler pluging to adhere to GCC in this release
  • Newlib
    • Updated to upstream 2.3 release
    • Added support for newlib-nano
  • OpenOCD
    • Support for the actionpoints. OpenOCD will automatically detect actions points in ARC EM and ARC HS targets. Hardware breakpoints are set via GDB command hbreak, while hardware watchpoints via GDB command watch.
  • Toolchain build scripts
    • 2-stage build process for baremetal toolchain
    • Can now build libc and libstdc++ optimized for size along the "normal" set of libraries.
    • Support for Linux toolchains with multiple sysroots. Buildscripts themselves can build a toolchain with only one sysroot, however that arc-snps-linux-uclibc/sysroot folder may be now freely used with other toolchains. That wasn't possible with previous releases, because some libraries were outside of the sysroot.
    • New options of build-all.sh script:
      • --[no-]elf32-gcc-stage1 - defines whether to build of stage 1 compiler for baremetal toolchain. Means that runnable ARC compiler should be already in the PATH to build newlib. Disable first stage compiler is needed for canadian cross builds. Default is --elf32-gcc-stage1.
      • --[no-]optsze-newlib - defines whether to build newlib optimized for code size. Default is --optsize-newlib.
      • --[no-]optsze-libstdc++ - defines whether to build libstdc++ optimized for code size. Default is --optsize-libstdc++. This is independent from newlib option, however nano.specs will be copied to target toolchain installation only when --optsize-newlib is used.
      • --[no-]elf32-strip-target-libs - defines whether to string target libraries of the debug symbols (except for .debug_frame section). Default is off --no-elf32-strip-target-libs.

Bugs Fixed in This Release (Summary)

  • Pre-built binaries
    • Fixed broken shortcut to documentation folder in installer for Windows
    • Fixed a bug where uninstaller for Windows wouldn't remove some shortcuts
  • Eclipse IDE
    • Fixed compatibility with Ashling Opella-XD gdbserver
    • Fixed an case where in C++ projects standard library functions were highlighted as unknown by Eclipse syntax checker.
    • Fix crash in IDE on Linux when connecting to target UART
    • Fixed: IDE template projects for C++ were not linking
    • Fixed: printf() is highlighted by Eclipse as an unknown function in C++ project, but projects builds without error
  • Newlib
    • Fixed an issue with string and memory routines using instructions which are not available for selected ARC processor configuration.
  • OpenOCD
    • Fixed support of EM7DFPU image in EM Starter Kit 2.1: JTAG frequency was too high.
  • Toolchain build scripts
    • Fixed an issue where custom baremetal toolchain built with -mnorm option wouldn't link C++ applications
