A Fuzzer for the Toy Optimizer

It’s hard to get optimizers right. Even if you build up a painstaking test suite by hand, you will likely miss corner cases, especially corner cases at the interactions of multiple components or multiple optimization passes. I wanted to see if I could write a fuzzer to catch some of these bugs automatically. But a fuzzer alone isn’t much use without some correctness oracle—in this case, we ...
