8  * This file should only be included in a project if there is a need to
9  * initialize the Trace Recorder before main() has been called.
10  * An example of this scenario is if you have a global object instance that has
11  * a constructor that creates an object that should be traced.
12  * This file will make it easier to initiate the recorder correctly.
13  *
14  * Usage:
15  * Add a call to TraceRecorderInit::Initialize() wherever a traced object is
16  * created before the Trace Recorder is normally initialized. This will ensure
17  * the Trace Recorder is initialized only once.
18  *
19  * Set TRC_CFG_RECORDER_DATA_PTR_INIT to 0 in trcSnapshotConfig.h to ensure
20  * RecorderInitialized isn't initialized to 0 after the recorder has been
21  * already initialized.
22  *
23  * Finally, call vTraceEnable(TRC_START) after hardware is initialized to
24  * start gathering trace events.
