Overview

The TI C28x code generation tools (C2000-CGT) facilitate the development of applications for TI C28x microcontroller platforms. The platforms include the Concerto (F28M3xx), Piccolo (280xx), Delfino floating-point (283xx), and C28x fixed-point (2823x/280x/281x) device families.

The TI C29x code generation tools (C29-CGT) are based on the open-source Clang compiler and its supporting LLVM infrastructure. The tools support the development of applications for TI C29x microcontroller platforms.

Code Composer Studio™ is the integrated development environment (IDE) for TI embedded devices. When starting development, it is recommended to begin by downloading Code Composer Studio as it includes the necessary TI compilers. For existing users of Code Composer Studio, compiler updates can be downloaded from within the environment.

Release Information

This is the 2.2.0.LTS Long-Term Support (LTS) release of the TI C29 Clang (c29clang) Compiler Tools. The c29clang compiler tools provide software development tools including the compiler, assembler, and linker, among others, which can be used to develop applications with C/C++ source code for loading and running on C29 core processors.

For definitions and explanations of STS, LTS, and the versioning number scheme, please see https://software-dl.ti.com/ccs/esd/documents/sdto_cgt_compiler_version_numbers_and_what_they_mean.html.

 

What's new

  • Support for link-time optimization with -flto
  • The compiler tools now support linking -mfpu=f32 code into -mfpu=f64 projects. Previously, this resulted in a link-time error.
  • Security support in linker command files have been enhanced with more options. See the Compiler User's Guide chapter "The Safety and Security Unit" for details.
  • New floating point mode: -mfpu=none, which emulates all floating point operations in general-purpose registers. Used to avoid saves/restores of floating-point registers on-entry to an interrupt.
  • At -O3, integer division sequences are now emitted inline, rather than called
  • Memory operations will more intelligently use the built-in address scaling of offset registers
  • General reduction of superfluous or redundant sign and zero extension
  • More performant C-library math.h functions via the use of -ffast-math or through intrinsics. See the Compiler User's Guide chapter "Built-In Functions and Intrinsics" for details.
