The GNU Compiler Collection (GCC) developers now have a need to set a policy whether AI / Large Language Model (LLM) generated patches will be accepted for this open-source compiler stack.
The GCC compiler doesn’t currently have a policy in place whether to permit AI/LLM-generated patches. But within a bug report today there is a patch posted by a user in trying to fix a GCC 16 compiler regression. The proposed patch notes:
“Fixed provided by GPT-5-CodeX fix the ICE for me.”
This patch generated by GPT-5-CodeX is a 123 line patch. The user having reported this GCC compiler bug and used SPT-5-CodeX to generate it is an Intel engineer.
Thus now a need for GCC developers to decide whether to permit or deny LLM-generated patches to upstream GCC.
A mailing list discussion thread was started to weigh whether to accept said patches. It was also suggested that the GNU Binutils policy, which is also used in large part by the Glibc project, could be a reasonable start. Their policy is to not accept LLM-generated patches out of copyright concern but that using an LLM to inspire/help may be okay as long as it’s not legally significant in the contributed changes and the usage of any LLM is clearly acknowledged.
So far in the mailing list thread no one has come out in favor of outright allowing complete LLM patches to be accepted, especially large patches such as what’s now on that GCC BugZilla ticket. It may ultimately come down to the GCC Steering Committee to formally decide a position on AI/LLM-generated patches but if the immediate comments are any indicator, it looks like GCC would probably not be allowing LLM-generated patches at least in the near-term.
