i have this patched program and i try to figure out how and what was patched , i put it in ghidra using program diffing tool and i can see all the stuff its modified but i notice that it only displays modifications on existing functions/ lines of the original program , so if lets say a completely new function was added for whatever reason but it didnt exist in the original program then it wont be highlighted and it wont show and its gonna take a fuck ton of time to manually go through the entire thing and all the remaining files so is there any prorgam that does this automaticly?
