SLINK builds an internal map into each executable. The location of this map is registered with SALFLIBC at runtime. It contains the true fixed-up runtime addresses. In the event of a fault during program execution that causes the program to abort, SALFLIBC will print out a traceback of the various routines called, tracing back to the user's main program.
The internal map contains the name and address of all the static and external functions in your code. You may wish (e.g. for code security reasons) to remove this map and forego the run time traceback facility. This may be achieved by using the notrace command.
