The long branches are an addon done with macros. The main problem in
implementing them natively is that the generated code is relocatable. This
means that not all expressions evaluate to constants as with simpler
assemblers. This means that you cannot simply go back and change anything,
because that in turn may change expressions all over the code. That does not
mean that it cannot be done, it does just mean that it is a lot more work
because of the relocation.
