The 2025 LLVM Developers' Meeting will host pre-conference workshops on October 27, and the main sessions are held October 28-29 in Santa Clara, California.

We welcome anyone who wants to attend, but this meeting will be particularly interesting to:

• Active developers of projects in the LLVM Umbrella (LLVM core, Clang, LLDB, libc++, MLIR, lld, etc).
• Developers of programming languages (ie. Rust or Swift) that use LLVM as their backend. 
• Anyone interested in using these as part of another project.
• Students and Researchers
• Compiler, programming language, and runtime enthusiasts.
• Those interested in using compiler and toolchain technology in novel and interesting ways.
• Those interested in diversity and inclusion in the field of compilers, tools, and open source.

Content is directed at newcomers and we highly encourage all to attend who have not been to an LLVM Developers’ Meeting before. However, we would like individuals that have attended before to come to this session and provide mentorship and a friendly face for our newcomers. So if you arrive in town a day early or for the workshops, please consider attending and supporting newcomers to this event.
