The MSP430 Optimizing C/C++ Compiler User's Guide describes additional run-time-support functions that are included in rts.src. If your program uses any of these functions, you must link the appropriate run-time-support library with your object files.
You can also create your own object libraries and link them. The linker includes and links only those library members that resolve undefined references.
