This is not a bug report but merely a question.

I have the impression that gcc assumes that the target machine must
have 32-bit (or at least "long" type) registers.  Can gcc be targetted
to a 16-bit register machine or a 64-bit register machine?

It looks like you need a new mode, say Rmode, to replace the embedded
SImode in some places.  For example, the move_block_to_reg routine in
in expr.c.
