--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> ---
The interrupt and exception handlers are called by x86 processors.  X86
hardware pushes information onto stack and calls the handler.  We need
a builtin function to access interrupt or exception data from the
interrupt and exception handlers which are void function without
arguments.
