GCC Will Not Accept LLM-Generated Code Contributions

The GCC steering committee has adopted a policy declining legally significant contributions that include or derive from LLM-generated content, using the existing GNU threshold of roughly fifteen lines. Maintainers may still accept machine-generated test cases, and using a model to research, analyse or review code stays permitted so long as its output does not enter the tree. The motivation is copyright rather than quality: GPL enforcement depends on a clean chain of title, which machine-generated text does not provide. Critics note it is undetectable in practice — systemd abandoned comparable tracking for exactly that reason — while Guix has proposed testing creativity instead of provenance.
