LLD is now provided in a separate formula:
    brew install lld

We plan to build LLVM 20 with `LLVM_ENABLE_EH=OFF`. Please see:
    https://github.com/orgs/Homebrew/discussions/5654

Using `clang`, `clang++`, etc., requires a CLT installation at `/Library/Developer/CommandLineTools`.
If you don't want to install the CLT, you can write appropriate configuration files pointing to your
SDK at ~/.config/clang.

To use the bundled libunwind please use the following LDFLAGS:
    LDFLAGS="-L$HOMEBREW_PREFIX/opt/llvm/lib/unwind -lunwind"

To use the bundled libc++ please use the following LDFLAGS:
    LDFLAGS="-L$HOMEBREW_PREFIX/opt/llvm/lib/c++ -L$HOMEBREW_PREFIX/opt/llvm/lib/unwind -lunwind"

NOTE: You probably want to use the libunwind and libc++ provided by macOS unless you know what you're doing.
