[Synopsys ARC] error: unable to interface with target machine

[marcospazianibrunella]

I'm trying to compile the code below:

int main () {
        return 1;
}

With Clang/LLVM 18.6.1 targeting Synopsys ARC with the following command:

$ clang --target=arc main.c -v
clang version 18.1.6 (https://github.com/llvm/llvm-project.git 1118c2e05e67a36ed8ca250524525cdb66a55256)

Is the target functional?
