Can I fuzz the my entire program (without using target_module and harness function)?

Can I fuzz the my entire program (without using target_module and harness function)?
I want my entire program to download and re-upload at each iteration.

Before answering, I should note that fuzzing a target without persistence will be extremely slow, as that would mean instrumenting the target anew for each iteration.

If I remember correctly, WinAFL's DynamoRIO mode does not support that, but TinyInst mode might. As an alternative, Jackalope fuzzer (https://github.com/googleprojectzero/Jackalope) for sure allows you to do this, but once again the performance loss without persistence is quite high and is thus not recommended for coverage-guided fuzzing.

Yes, it works only with TinyInst. Thanks!
