Some disassemblers (at least available for some other processor architectures) can do this, by their flowcharting of the instructions and noting that the only references to the table are indexed table-lookup instructions - no calls or jumps. In this case, they sometimes manages the reverse - they may fail to notice a computed indexed call, in which case the disassembly can contain a table of values when the data should have been disassembled into instructions instead.


This is obviously the route to go. Source is king. For own projects, the source code should be backed up and stored safely at multiple locations. For competitors products, the code is probably under copyright in which case it would be unethical - or illegal - to reverse engineer it.
