There are plenty llvm related tools (more than 100).

I‘ve wrote a script to glob all llvm tools instead of manually specify them , tested on Ubuntu 22.04 x86_64.

It would automatically glob all the tools in /lib/llvm-${VERSION} as slave commands of /usr/bin/clang-{VERSION}

See: https://github.com/ShangjinTang/dotfiles/blob/05ef87daae29475244c276db5d406b58c52be445/linux/ubuntu/22.04/bin/update-alternatives-clang

To use it (requires sudo permission):

wget https://raw.githubusercontent.com/ShangjinTang/dotfiles/05ef87daae29475244c276db5d406b58c52be445/linux/ubuntu/22.04/bin/update-alternatives-clang
sudo bash ./update-alternatives-clang

Result:

I had to add a bunch of other slaves to clang config, including clangd, clang-tidy, etc.
