Chromium explicitly does not: | Chromium ships a prebuilt clang binary. It's just upstream clang built | at a known-good revision that we bump every two weeks or so. | | This is the only supported compiler for building Chromium. <https://chromium.googlesource.com/chromium/src/+/master/docs/clang.md> Currently, it's this build: $ ./src/third_party/llvm-build/Release+Asserts/bin/clang++ --version clang version 11.0.0 (https://github.com/llvm/llvm-project/ a6ae333a0c23fc9b0783ca45e2676abac00c6723) Target: x86_64-unknown-linux-gnu Thread model: posix InstalledDir: /home/test/chromium/./src/third_party/llvm-build/Release+Asserts/bin So something pulled recently from the development branch, not a release branch. In my experience, this is pretty typical: Upstreams leaning towards Clang expect that you use their prebuilt compiler, not a system compiler. Using Clang downstream may make things simpler for packagers, but a system-supplied Clang compiler is rarely a preferred upstream choice (not even on Macos, where there is no real choice anymore). On the other hand, there is demand from users (not just packagers) for the LLVM-based toolchain, and increased use by Fedora packagers will help us to improve the quality of Fedora's version of it. Fortunately, for this effect, it does not matter *why* Fedora packagers choose Clang.
