Changes Between Different Versions of Arm Compiler 6

Chapter 6 Changes Between Different Versions of Arm® Compiler 6

A description of the changes that affect migration and compatibility between different versions of Arm® Compiler 6.

Note:

  • Arm does not guarantee the compatibility of C++ compilation units compiled with different major or minor versions of Arm Compiler and linked into a single image. Therefore, Arm recommends that you always build your C++ code from source with a single version of the toolchain.

    You can mix C++ with C code or C libraries.

  • All C++ compilation units that are to be linked into a single image must be compiled with the same version of the C++ standard library ABI. If the ABI version changes between Arm Compiler releases, then you must recompile your object files.

    If you are unable to recompile some of your object files, then contact Arm Support at https://developer.arm.com/support.

Note:

The documentation changes for Arm Compiler 6.15 and later releases are listed in an appendix for each document.
