Hello! Welcome to the LLVM 20.x release! The first RC is now tagged. Run your tests, build your binaries, create issues and upload your binaries.

Instead your should upload your binaries to any hosting you chose and then post about the release in the official Third-Party forum thread.

Thanks for all the hard work to verify and improve LLVM!

@tstellar Are you planning to build any of the AArch64 and Arm Linux/Windows binaries? If not I will build/test and upload those just like LLVM 19 release.

Testing went reasonably good so far:

  • No (notable) regressions on either sparcv9-sun-solaris2.11 and amd64-pc-solaris2.11.
  • Lots of libcxx/test/benchmarks failures on both x86_64-pc-linux-gnu (Issue #125510) and sparc64-unknown-linux-gnu (fixed by PR #125503).

@omjavaid We have AArch64 builds for Linux on the release page now, but no ARM Windows binaries.

I’ve uploaded x86 and x86_64 Windows binaries to the release page. Didn’t hit any issues.
