All versions of clang on all version of macOS use the clang_rt.

You can see a very interesting view of what clang does in the background for you by compiling a simple “hello.c” application with some verbose flags to the compiler and linker like this:

clang -v -Wl,-v hello.c

You might be surprised by all the things done in the background to make it work for you.
