Comment at: clang/lib/Driver/Driver.cpp:4391
DDep.add(*PackagerAction, *C.getSingleOffloadToolChain<Action::OFK_Host>(),
- nullptr, Action::OFK_None);
+ nullptr, C.getActiveOffloadKinds());
}
----------------
`getActiveOffloadKinds` returns a mask of offload kinds, yet we cast it to
`OffloadKind` in `DeviceDependences::add` above. This mixing of OffloadKind and
sets of them looks questionable to me.
If we are relying on passing sets of `OffloadKind`now, then we should make it
clear in the code that it is the intent, including a more detailed description
that `DeviceOffloadKinds` is a list of `OffloadKind` sets, so whoever iterates
over elements does not attempt to compare its elements with `OffloadKind`
values. I think it would be helpful to change `DeviceOffloadKinds` element type
to a new class with a helper method `hasOffloadKind(OffloadKind)` to avoid
accidental comparison of a mask with enum value.
