[Quentin Colombet via Phabricator via llvm-commits]

> Those rules work when there's a load/store for every type but they run into unable-to-legalize if that's not the case.

Indeed, and that was the intent. For the case that are not true, like in the example you describe, the target has to support those cases with custom expansion or other. In other words, what you describing get into specifics we didn't want to cover initially in the generic code.
