There was something similar, called Dissi IIRC, for the British RISC
OS machines manufactured by the now-defunct Acorn Computers Ltd
(designers of the original ARM chips).


It's additional feature was that it would emulate the processor
starting from the entry point of the executable or any other place
that you identified as code as opposed to data. From this it would
mark many more words as code through taking both paths from each
conditional jump.


Once it had exhausted its current stack of starting points you could
look through the listing to identify further ones.




Ralph.
