Hi Prateek, Further research on the project: - Look at the gcc language extensions in the gcc documentation. Select some (can be one or a combination of multiple) of suitable complexity and get familiar with the concepts. Examples are OpenMP, transactions, vector extensions. For some of them the gcc documentation is enough, for others (like OpenMP or transactions) you'll need to download the external specification. Look at the specification and get familiar with it. Likely you'll also need to do some research in the underlying concepts (e.g. parallelism for OpenMP or vectorization for the vector APIs) - Look at csmith or yarpgen and get familar with the code Then you can make a choice which fuzzer you want to use as a base and make a proposal which gcc extensions you would want to target with the project. -Andi
