I think you are right. I'm sorry, that whole thing is a bit confusing to me. But the initializer is used in the construction of a subobject, which is different from a default argument which is initialized on call site... so I think the conclusion is that we should do nothing for default inits, I think https://github.com/llvm/llvm-project/pull/76361 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
