GCC's accepted AI policy declines LLM-derived contributions above the GNU 15-line threshold

Sources: LWN, gcc mailing list, July 2026, discussion
Summary: LWN published a brief quoting the accepted GCC AI policy text. Contributions derived from an LLM are declined above the GNU maintainer guidelines threshold of around 15 lines of code or text. Test cases are left to maintainer discretion. Using an LLM for research, bug reporting, and patch review stays allowed. The July 2026 gcc mailing list index confirms the announcement thread and its replies, and individual message URLs could not be resolved this run.
Why it matters: Contributors get a concrete line-count test to apply rather than a general prohibition, and this replaces the single-source account the 2026-07-29 digest carried as developing.
