shafik added a comment.
This looks good to me but I see at least one concern that Aaron had that he did
not get back on, so I will wait for him to approve.
================
Comment at: clang/lib/AST/Interp/ByteCodeExprGen.cpp:835
IsTemporary = true;
Ty = E->getType();
}
----------------

I think it should be an `else if` we either have a `Decl` or an `Expr` right?
================
Comment at: clang/lib/AST/Interp/ByteCodeStmtGen.cpp:408
// Compile the initializer in its own scope.
- {
+ if (Init) {
ExprScope<Emitter> Scope(this);
----------------
So by moving the check for `Init` forward, we will still allocate but we may
not initialize.
================
Comment at: clang/lib/AST/Interp/Descriptor.h:73
+ /// Flag indicating if the field is mutable (if in a record).
+ unsigned IsMutable : 1;
+
----------------

I am happy fixing this separately, please leave a `TODO`
================
Comment at: clang/lib/AST/Interp/Interp.h:918
return false;
+ if (!Ptr.isRoot())
+ Ptr.initialize();
----------------
Can you explain what is going on here? Why do we need to initialize if it is
not root?
