That's kind of an extreme case.  But it sounds like you are following
the right approach.

Well, you have to look at the generated code, find out where it is
wrong, and fix it.  There is no royal road to success.  It's always
hard to write a new gcc backend.  And since your backend is so
unusual, it's likely to be unusually hard.
