| Message-ID | <25-01-001@comp.compilers> |
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. https://arxiv.org/abs/2501.00655 Regards, John Levine, johnl@taugh.com, Taughannock Networks, Trumansburg NY Please consider the environment before reading this e-mail. https://jl.ly
