You might try to disassemble the code for a bunch of ISAs and see if your disassembly produces meaningful function prologue & epilogue for that ISAs ABI. Automatically. Not sure if someone is doing that. Our (commercial) disassembler for example is told by the user what target it's disassembling (and I usually look at the output, not the actual opcodes; so maybe that's not feasible).
