+/// \file ppc405_irq_core.c
+/// \brief Core IRQ routines required of any PPC405 configuration of SSX
+///
+///  This file is mostly only a placeholder - where 'extern inline' API
+///  functions and 'extern' variables are realized.  A couple of default
+///  handlers are also installed here.  The entry points in this file are
+///  considered 'core' routines that will always be present at runtime in any
+///  SSX application.
+
+#define __PPC405_IRQ_CORE_C__
+
+#include "ssx.h"
+
+/// This function is installed by default for interrupts not explicitly set up
+/// by the application.  These interrupts should never fire.

+__ppc405_default_irq_handler(void     *arg,

+{
+    SSX_PANIC(PPC405_DEFAULT_IRQ_HANDLER);
+}
+
+
+/// This function is installed by default to handle the case that the
+/// interrupt dispatch code is entered in response to an external critical or
+/// non-critical interrupt, but no interrupt is found pending in the interrupt
+/// controller.  This should never happen, as it would indicate that a
+/// 'glitch' occurred on the external noncritical or critical interrupt input
+/// to the PPC405 core.
