- *  Assembly-level exception handler used when no handler was
- *  registered for the specific exception cause.
- *
- *  The BREAK instruction is used to give control to the debugger,
- *  if one is present and active.  (If none is present and active,
- *  the default debug exception handler will typically skip over
- *  this break instruction.)
- *  This code follows the convention documented in the ISA manual
- *  to use BREAK instructions to signal unhandled exceptions to the
- *  debugger.  For the debugger to report or handle this condition
- *  in an OS-independent manner, all processor state (except PC)
- *  must be restored as it was when the unhandled exception just
- *  occurred (ie. as it was at the beginning of the vector).
- *  If execution continues after the BREAK instruction (in which
- *  case any register might have been modified by the debugger),
- *  just return.
