Hmm, that d10v example made me think ...

The d10v has 16 bit code pointers.  They are mapped onto a core addr using:

	((code_ptr) << 2) | 0x01000000)

The key thing being the code pointer has a granularity of 32 bits (aka 4 
bytes).

Given the expression:

	((int32 @code *) func)[1]

I can guess what it does.  However, what about:

	((int16 @code *) func)[1]

I suspect that the proposed model would result in ``[1]'' and ``[0]'' 
being the same location.
