[PATCH] D56760: Add a new builtin: __builtin_dynamic_object_size

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

Thanks, this seems like a useful feature to me.

Would it make sense to model this as an (optional) extra flag bit for `__builtin_object_size` rather than as a new builtin? It'd seem reasonable to me to ask on the gcc dev list if they'd be interested in such an extension to their builtin -- if not, then we should use a new name, and something like this seems fine to me.
