The GCC steering committee has announced that it has accepted an AI contributions policy recommended by the GCC AI policy working group.
The policy, in part, states that the project will decline any "legally significant contributions which include LLM-generated content or are derived from LLM-generated content
". It uses the definition of "legally significant" from the GNU Project maintainer guidelines, which holds that the threshold is "around 15 lines of code and/or text
" to qualify as significant for copyright purposes. GCC maintainers may, however, choose to accept legally significant test cases that are generated by an LLM.
The policy does not forbid use of LLMs for research, analysis, bug discovery and reporting, patch review, etc. as long as the output is not included in contributions. The committee says that it expects the policy will evolve and will be revisited periodically.
