Modify Source Code

Replace the source code of the main.cpp file of your project with the source code shown in the listing below. To open the main.cpp file:

1. Expand the Sources node of your project in the CodeWarrior Projects view.
2. Double-click main.cpp to open its contents in the editor area.

You need to modify the source code such that it uses the profiler API to do profiling. This source code uses:

• The ProfilerInit() function to initialize the profiler - With profiling on, the compiler generates all the necessary code so that every routine calls the profiler.
• The ProfilerDump() function to write the profiling data into the profiledump.mwp file
• The ProfilerTerm() function to terminate the profiler - If you initialize the profiler and then exit the program without terminating the profiler, timers may be left running that could crash the machine.

The source files that make calls to the profiler API must include the appropriate header file for your target. The header file that the ColdFire V4e target uses for profiling is:

  #include <Profiler.h>

#include <stdio.h>

#include <Profiler.h>
