7.5: Default Fatal Error Processing
The default fatal error handler for this architecture performs the
following actions:
- places the error code in r3, and
- executes a trap instruction which results in a Program Exception.
If the Program Exception returns, then the following actions are performed:
- disables all processor exceptions by loading a 0 into the MSR, and
- goes into an infinite loop to simulate a halt processor instruction.
