[PATCH] D65511: Delay emitting dllexport explicitly defaulted members until the class is fully parsed (PR40006)

[Reid Kleckner via Phabricator via cfe-commits]

rnk added inline comments.


================
Comment at: clang/lib/Sema/SemaDeclCXX.cpp:11545
+    for (CXXMethodDecl *M : WorkList) {
+      DefineImplicitSpecialMember(*this, M, M->getLocation());
+      ActOnFinishInlineFunctionDef(M);
----------------
Do we need to do this until fixpoint? Suppose a dllexported implicit special member triggers a template instantiation, and the template has a dllexported defaulted special member, something like:
```
struct Bar { Bar(); };
template <typename T> struct Foo { __declspec(dllexport) Foo() = default; Bar obj; };
struct Baz {
   ... not sure how to trigger instantiation
};
```
