2.4.2 Linker

The tool chain's linker remains the TI linker, not the LLVM linker. This means that, in general, the syntax of linker command files does not change. However, the way that a linker command file is specified during compilation has changed. This page contains detailed information on Linker flags within LLVM. Information on migrating linker command files for use with the C29 compiler is available here.

Before:

cl2000 a.c -z -llnk.cmd

After:

c29lang a.c -Wl,-llnk.cmd
  • There are some features implemented for the C28 compiler that interacted with the TI linker and involved unique specification in the linker command file. Where these features are applicable to the C29, they will be addressed in a future version of the compiler e.g. Live Firmware Update (LFU), which is supported by the C28 Compiler.
