This direction is currently reserved to our upcoming GSoC 2026 project: https://discourse.llvm.org/t/gsoc-2026-libc-enable-float80-and-float128-math-support-on-unsupported-targets-for-llvm-libc/89647, and I prefer to not having duplicated work done. Please keep in touch with us on discord or discourse about what you plan to do. Thanks!

No worry.  You can feel free to experiment with these in your own fork of LLVM project, just don't create PRs for the official repo yet.

You can join our libc channel on discord (https://discord.gg/xS7Z362) or our regular LLVM libc math meeting (https://discourse.llvm.org/t/fortnightly-llvm-libc-math-library-meeting/89166) for discussion.  There are plenty of things that you could try to get familiar with the codebase and start contributing.
