Automatically generating those yaml configuration files can help checker understand how the taint propagate after calling a function written in another file. </div><div><br></div><div>To know if passing a tainted argument into a function will lead to any OOB error in callee, we may also need to record: for each argument, if it is tainted, whether a warning will be generated. And the second scan can use this information in PreCall to check if it is safe to pass the argument into that function.</div><div><br></div><div>This is my current thought about a possible approach, and I may ask more questions when trying to implement it because it is my first time work with LLVM, I greatly appreciate your help.</div><div><br></div><div>Sincerely,</div><div>Gavin</div>
