• Paper: Finding Missed Code Size Optimizations in Compilers using LLMs

    From John R Levine@21:1/5 to All on Fri Jan 3 12:23:10 2025
    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.
