1. Get the latest Assignment-4 code template

* Before coding, please type cd $HOME/SVF-Teaching and git pull in your terminal to make sure you always have the latest version of the code template before each assignment.

If git pull fails due to the conflict with your local changes, type git stash to store your current code in a temporal branch and type git pull again. If you want to retrieve your code back, type git stash pop.

2. Assignment 4 task

1. Implement readSrcSnkFromFile, printICFGPath and aliasCheck of class TaintGraphTraversal in Assignment-4.cpp
2. Pass the test without any assertion by Test4.cpp
3. Submit Assignment-4.cpp to canvas

SVF APIs to help with your implementation SVF CPP API.

*You will be working on Assignment-4.cpp only and there is NO need to modify other files under the Assignment-4 folder

3. Debugging and test cases.

We provided two test cases with their corresponding LLVM bc files.

Make sure you previously implemented Assignment-2.cpp and Assignment-3.cpp are in place. Class TaintGraphTraversal is a child class of ICFGTraversal and will use the DFS method implemented in Assignment 2 for control-flow traversal. Andersen's analysis implemented in Assignment 3 will also be used for checking aliases between two pointers.

• readSrcSnkFromFile: general C++ file reading link1, link2, link3, link4.
• printICFGPath : similar to printICFGPath in Assignments 2 and 3.
• aliasCheck: please follow the SVF APIs here
