I assume that you want permutations since you want to make sure that the
ordering does not matter, right? If you just care about combinations then
```
asm inline goto volatile("" ::::foo);
asm inline volatile goto("" ::::foo);
asm goto inline volatile("" ::::foo);
asm goto volatile inline("" ::::foo);
asm volatile goto inline("" ::::foo); // note, this one should probably be
added in permutations
asm volatile inline goto("" ::::foo);
```
could just be distilled down to one of those since they are the same
combination of qualifiers (combinations do not care about order). I would say
that moving `combinations` into `permutations` would be wise since
`permutations` tests the same thing that `combinations` does and more.
