GCC compiler development team publishes policy on accepting AI-generated code, rejects AI-generated code of 15 lines or more

The GCC development team has formalized a policy on AI-generated code contributions.

LLM-generated or LLM-derived legally significant contributions will not be accepted in principle.

Under GNU guidelines, code or text over roughly 15 lines is considered legally significant, so AI-generated submissions of that size are effectively barred.

Shorter outputs may be allowed with conditions and an AI-use tag, while test cases remain an exception.
