rnk added a subscriber: hans. rnk added a comment. Regarding the usage of isPOD in the MSVC ABI code, we should have a routine similar to `isTrivialForAArch64MSVC` that works for the other MSVC architectures that we support (x86, x64, and arm32). I don't think we should try to rely on definition data bits. Clang is almost always tracking something slightly different than what MSVC tracks, so we should write down MSVC's logic once and keep it separate from Clang's notion of POD.
I think you can work out MSVC's behavior with godbolt, but if you need a hand, I volunteer @hans to take a stab at refactoring `MicrosoftCXXABI::classifyReturnType`. I remember making lots of comments to try to simplify the code during review, but everyone is always wary of scope creep.
