Log:
In Sema, whenever we think that a function is going to cause a
vtable to be generated, we mark any virtual implicit member
functions as referenced.
Added:
+void Sema::MaybeMarkVirtualImplicitMembersReferenced
(SourceLocation Loc,
+
CXXMethodDecl *MD) {
+ // Ignore dependent types.
+ if (MD->isDependentContext())
+ return;
+
+ CXXRecordDecl *RD = MD->getParent();
+ const ASTRecordLayout &Layout = Context.getASTRecordLayout(RD);
This, I believe, is the first use of getASTRecordLayout in Sema. Is
there any other way to get the
key function without resorting to this overhead?
We do use getASTRecordLayout for sizeof, alignof and
__builtin_offsetof already.
Yes, but this is when user asks for it; not for internal code gen
purposes.

We could put the key functions in a separate map, but I don't think
it's worth it.
