##
## Purpose: Processes all compiled object files into 2 types of files which assist in debuging applications.
##          File 1: .addr: A sorted list of function starting addresses. 
##                  When a the PCE is greater than or equal to the function's starting address, the label will be associated with this address.
##          File 2: .lab: A sorted list of funciton labels. The names of functions.  Modelsim will display these names rather than the function address.
