I spoke offline with Matthew Riley, who recommended that I nominate myself to join the LLVM security group as a representative of Google. In particular, I intend to register as a vendor contact. I work primarily with toolchains and toolchain teams focused on our open source projects (e.g., Chrome, Chrome OS, Android, ...), and some security-critical parts of varying levels of open-source-ness under those banners. :)
We believe that adding myself as the second representative for Google will help improve the robustness of Google's response to any potential future security issues that the LLVM project may encounter.
Please let me know if I can provide any other information, or if I missed anything in this nomination.
Thank you for your time!
