Instead of going in this direction, I think you may be more mileage
going a different route.  One reason to not favor going this route is
that the above is so poorly specified that I don't have a good notion
of what you mean, nor would the compiler.

Before going down that path, I'd recommend exposing the jump to the
compiler through the use of if, or goto in the higher level language.
Do that, and then explain the problems that develop and we can try and
solve those.  Those are the real problems.

This concept is called, stop lying to the optimizer.  The reason why
you want to, is because everytime you do, it will hurt.  If you are
patient and explain what your doing to the optimizer, it will not hurt
you as often.
