+/********************* function asm_handle_exception ***************************
+* *
+* This function handles an exception. It does not use the usual calling *
+* conventions. The exception pointer is passed in REG_ITMP1 and the *
+* pc from the exception raising position is passed in REG_ITMP2. It searches *
+* the local exception table for a handler. If no one is found, it unwinds *
+* stacks and continues searching the callers. *
+* *
+* void asm_handle_exception (exceptionptr, exceptionpc); *
