LLVM Community Code of Conduct

The LLVM community has always worked to be a welcoming and respectful community, and we want to ensure that doesn’t change as we grow and evolve. To that end, we have a few ground rules that we ask people to adhere to:

This isn’t an exhaustive list of things that you can’t do. Rather, take it in the spirit in which it’s intended - a guide to make it easier to communicate and participate in the community.

This code of conduct applies to all spaces managed by the LLVM project or The LLVM Foundation. This includes IRC channels, mailing lists, bug trackers, LLVM events such as the developer meetings and socials, and any other forums created by the project that the community uses for communication. It applies to all of your communication and conduct in these spaces, including emails, chats, things you say, slides, videos, posters, signs, or even t-shirts you display in these spaces.

In rare cases, violations of this code outside of these spaces may affect a person’s ability to participate within these spaces. Important examples include sexual and gender-based violence, hate crimes, and hate speech. We do not conduct proactive research, but we have an obligation to respond to any reported concerns. We are not interested in evaluating severity, responding punitively, or holding people accountable. Both the relevance and our response is instead focused on how a person’s continued participation impacts the community’s safety, wellbeing, and inclusivity. We specifically prioritize remaining a welcoming community to victims as well as groups subjected to systemic marginalization or underrepresentation.

In addition, violations of this code outside these spaces may, in rare cases, affect a person’s ability to participate within them, when the conduct amounts to an egregious violation of this code.

If you believe someone is violating the code of conduct, we ask that you report it by emailing conduct@llvm.org. For more details please see the Reporting Guide.

  • Be friendly and patient.

  • Be welcoming. We strive to be a community that welcomes and supports people of all backgrounds and identities. This includes, but is not limited to members of any race, ethnicity, culture, national origin, colour, immigration status, social and economic class, educational level, sex, sexual orientation, gender identity and expression, age, size, family status, political belief, religion or lack thereof, and mental and physical ability.

  • Be considerate. Your work will be used by other people, and you in turn will depend on the work of others. Any decision you take will affect users and colleagues, and you should take those consequences into account. Remember that we’re a world-wide community, so you might not be communicating in someone else’s primary language.

  • Be respectful. Not all of us will agree all the time, but disagreement is no excuse for poor behavior and poor manners. We might all experience some frustration now and then, but we cannot allow that frustration to turn into a personal attack. It’s important to remember that a community where people feel uncomfortable or threatened is not a productive one. Members of the LLVM community should be respectful when dealing with other members as well as with people outside the LLVM community.

  • Be careful in the words that you choose and be kind to others. Do not insult or put down other participants. Harassment and other exclusionary behavior aren’t acceptable. This includes, but is not limited to:

    • Violent threats or language directed against another person.

    • Discriminatory jokes and language.

    • Posting sexually explicit or violent material.

    • Posting (or threatening to post) other people’s personally identifying information (“doxing”).

    • Personal insults, especially those using racist or sexist terms.

    • Unwelcome sexual attention.

    • Advocating for, or encouraging, any of the above behavior.

    In general, if someone asks you to stop, then stop. Persisting in such behavior after being asked to stop is considered harassment.

  • When we disagree, try to understand why. Disagreements, both social and technical, happen all the time and LLVM is no exception. It is important that we resolve disagreements and differing views constructively. Remember that we’re different. The strength of LLVM comes from its varied community, people from a wide range of backgrounds. Different people have different perspectives on issues. Being unable to understand why someone holds a viewpoint doesn’t mean that they’re wrong. Don’t forget that it is human to err and blaming each other doesn’t get us anywhere. Instead, focus on helping to resolve issues and learning from mistakes.


If you believe someone is violating the code of conduct you can always report it to the LLVM Foundation Code of Conduct Committee by emailing conduct@llvm.org. All reports will be kept confidential. This isn’t a public list and only members of the advisory committee will receive the report. For details on what to include in the report, please see the Reporting Guide.

If you believe anyone is in physical danger, please notify appropriate law enforcement first. If you are unsure what law enforcement agency is appropriate, please include this in your report and we will attempt to notify them.

If the violation occurs at an event such as a Developer Meeting and requires immediate attention, you can also reach out to any of the event organizers or staff. Event organizers and staff will be prepared to handle the incident and able to help. If you cannot find one of the organizers, the venue staff can locate one for you. We will also post detailed contact information for specific events as part of each events’ information. In person reports will still be kept confidential exactly as above, but also feel free to (anonymously if needed) email conduct@llvm.org.


The code of conduct committee may decide to ban an individual from the community for violating the code of conduct. The goal of a ban is to protect community members from having to interact with people who are consistently not respecting the code of conduct. Please refer to the Developer Policy section on Bans for how to handle interactions with former community members. If you need further guidance, please contact conduct@llvm.org.
