Overview

The TI Arm® code generation tools support development of applications for TI Arm-based platforms, especially those featuring TI Arm Cortex-M and Cortex-R series devices. There are now two TI Arm® C/C++ compiler toolchains both of which can be used to compile and link C/C++ and assembly source files to build static executable applications that can be loaded and run on Arm® Cortex-M and Cortex-R series devices.  Depending on the device family a specific compiler toolchain will be recommended.  Please refer to the SDK or software package for the device for information on which toolchain to use.

  • The new TI Arm® Clang Compiler Tools (ARM-CGT-CLANG-X) is derived from the open source clang compiler and its supporting LLVM infrastructure. All new feature development going forward will be done in the TI Arm® Clang Compiler Tools.
  • The TI Arm® C/C++ Compiler Tools (ARM-CGT-XX) will continue to be maintained as long as necessary. However, only bug fixes will be provided in maintenance releases of v20.2.x.LTS of the legacy TI Arm® C/C++ Compiler Tools.
Code Composer Studio is the Integrated Development Environment (IDE) for TI embedded devices.  If you are looking to develop on a TI embedded device it is recommended to start by downloading Code Composer Studio as it includes the TI compilers.  If you are already a user of Code Composer Studio the best way to update the compiler is to go to the Help menu and select to install compilers (please see Getting compiler updates in CCS for more details).

Features
  • TI Arm® Clang Compiler Tools release 1.3.0.LTS:
    • Improved compiler-generated code size vs. legacy TI compiler
    • GCC-compatible compiler command-line interface
    • Source-Based Code Coverage, including Branch Coverage
      • With tiarmprofdata and tiarmcov utilities to help with visualization
    • Support for Arm C Language Extensions (ACLE)
    • Migration Aids for porting projects built with the legacy TI compiler to use the new TI Clang compiler
       
  • TI Arm® C/C++ Compiler Tools release 20.2.x.LTS:
    • C++ 2014 Support and C++ ABI Compatibility
    • Support for Arm C Language Extensions (ACLE)
    • LLVM-based object file utilities: objcopy, objdump, readelf, size
    • Continues support for other Arm processor variants, including: v4, v5e, v6, and v7a8

TI Compiler Support

Long-term and short-term support

Long-term support (LTS) releases are actively maintained for approximately two years with reported defects being repaired as follows:

    • Production stop defects are addressed within 2 weeks,
    • Critical defects are addressed within 90 days, and
    • Defect repairs are proactively applied to each release stream

Short-term support (STS) releases are only supported until the next release becomes available meaning that:

    • Only production stop defects may cause patch releases to be created,
    • Patch releases for STS releases will not be planned, and
    • Defect repairs will not be proactively applied to each release stream
    • For more information about the distinction between LTS and STS compiler releases, please see the article: Introduction to LTS and STS Compiler Releases

  • Optimizing C/C++ Compiler
  • Assembler
  • Linker
  • C/C++ standard header files
  • C/C++ runtime libraries
  • Object file display and manipulation utilities
