This is the assignments of the Code Analysis and Transformation class at Northwestern University (2023 Fall).

Website of the class: https://users.cs.northwestern.edu/~simonec/CAT.html

To build:

• Compile and install your code by invoking ./run_me.sh.
• The script run_me.sh compiles and installs an LLVM-based compiler that includes your CAT in the directory ~/CAT.

To run:

1. Add your compiler cat-c in your PATH (i.e., export PATH=~/CAT/bin:$PATH)

2. Invoke your compiler to compile a C/C++ program. For example:

   $ cat-c program_to_analyse.c -o mybinary
   $ cat-c -O3 program_to_analyse.c -o mybinary
   $ cat-c -O0 program_to_analyse.bc -o mybinary
