[PATCH] D119051: Extend the C++03 definition of POD to include defaulted functions

[Reid Kleckner via Phabricator via cfe-commits]

rnk added a comment.

I would structure this as a LangOpt, and feed the target checks and ABI compat checks into the default setting for it. It could be something like `DefaultedSMFArePOD` / `-f[no-]defaulted-smf-are-pod` (smf being special member functions). The LangOpt default is true, and the driver fills in the value from the target and ABI version in the case of no explicit flag.

I think the DeclCXX changes are probably in the right place. I don't think it makes sense to carry around separate `isPOD` bits according to the C++11 and C++03 rules, just so we can use them later to make these two specific, known ABI-impacting decisions.
