Two people from Meta/Facebook took some trivial programs, used LLMs to
add code that should be optimized away, and looked for compiler
crashes or suspicious increases in object code size. They found a
bunch of optimization bugs.
Previous code mutators have been large and complex, but this one using an
LLM is 150 lines of code.
