Yes, an external assembler pass would be too slow. Is anyone using the
New Jersey Machine-Code Toolkit as part of a JIT or dynarec?

Why extra passes? A different backend would be used per architecture,

Some more for you to read could be found at www.dynarec.com. They're
interested in dynamic re-compilation where machine instructions from
one architecture are converted on the fly to another. Sometimes an
intermediate format is used.
