llvm-nullptr

An LLVM pass that aims to detect bad pointer usage in C code. Assignment for a compiler course.

Heavy WIP: initial commit only supports bad pointer usage without taking control flow into account.

Build:

$ cd llvm-nullptr
$ mkdir build
$ cd build
$ cmake ..
$ make
$ cd ..

Run:

$ clang -Xclang -load -Xclang build/nullp/libNullpPass.* something.c
