to install cargo and rustc (for compilation and running): run this script https://rustup.rs/
make -> ./bin/ekcc --help
We fuzz tested our compiler using afl.rs, which is an AFL library for fuzzing Rust code. To install/run the fuzzer, run make fuzz.
further documentation for rust afl can be found at https://rust-fuzz.github.io/book/afl.html
The fuzz tester found that reading larger integer literals than rust's i32 type can hold causes a crash. Specifically, the fuzzer found a crash based on code containing the following line:
if ($n == 0)222222222222222222220;
The full input that caused the crash can be found at:

Test cases for optimization benchmarking are in final-optimization-benchmarks/. To run optimization benchmarks, run python3 run_tests.py and find the output in results/. To add optimization benchmarking for another file, append a line similar to the others at the end of run_tests.py with the relative or absolute path of the ek file and re-run the benchmarks.
A full report on the optimization benchmarking results is available in this directory as Assignment 6 Report.docx or Assignment 6 Report.pdf.
