<pre>I would expect clang to return non-zero when the output is not generated.
```
$ clanh -c -o hello2.o hello.o
clang-9: warning: hello.o: 'linker' input unused
[-Wunused-command-line-argument]
$ echo $?
0
$ stat hello2.o
stat: cannot stat 'hello2.o': No such file or directory
```
I noticed gcc has the same behavior, but still I would expect `clang: error: no
input files` after the warning and a non-zero return code.
Another way of putting it: if all inputs are unused I would expect "no input
files" error.</pre>
