Correct. It may be fixable, but there's basically zero interest in fixing it.
Qemu is pretty much the only place where this particular behaviour (a single 
ret at the end of the code) is required or even desirable. In fact the 
opposite is usually true - you want the fast path to be as short as possible 
for better cache locality.

IMHO the way forward long-term is to implement some sort of code generation in 
qemu. By this I mean incorporating some sort of compiler backend/optimizing 
assembler into qemu, not just writing op.c in assembly. Obviously this is a 
large chunk of work.
