As far as I can see, `-filetype=asm` is the default in `llc`. Furthermore, it is [advised](https://llvm.org/docs/TestingGuide.html#fragile-tests) to pass the input to `opt` via redirection - not sure if it has any relation to `llc` (except for uniformity), but using `< %s` makes `-o -` useless, too.
