4. Migrating C and C++ Source Code

The process of converting the C/C++ source code for an existing TI C28x application that is built with the cl2000 compiler so that it can be built using the c29clang compiler can be thought of as the process of making your C/C++ source code portable. The cl2000 compiler supports the use of proprietary TI-specific versions of many predefined macro symbols, intrinsics, and pragmas that are not supported by other compilers. The use of such proprietary TI mechanisms will render a program unbuildable by other compilers, including the c29clang compiler.
