That is an admirable goal, but in this case I think you are going to
have to change the middle-end to make your port work.  I recommend that
you contribute the patches back to gcc mainline for the benefit of other
users.  Of course this will require a copyright assignment or
disclaimer.

The small patch you sent looks quite reasonable.
