oops?

Comment at: lldb/source/Plugins/SymbolFile/NativePDB/UdtRecordCompleter.cpp:96
CompilerType method_ct = m_ast_builder.ToCompilerType(method_qt);
- lldb::opaque_compiler_type_t derived_opaque_ty =
m_derived_ct.GetOpaqueQualType();
+ PdbAstBuilder::RequireCompleteType(method_ct);
+ lldb::opaque_compiler_type_t derived_opaque_ty =
----------------
I suppose this won't hurt, but `RequireCompleteType` will not actually do
anything for method types, right ?
Regarding method types, there is a slightly different problem. C++ rules
require that in code like
`struct B1 { virtual A1* f(); }; struct B2:B1 { A2* f(); };`, the types `A1`
and `A2` must be complete (because that code is only valid if A1 is a base of
A2). However, I think that's better left to a separate patch.

Comment at: lldb/source/Plugins/SymbolFile/NativePDB/UdtRecordCompleter.cpp:159
CompilerType member_ct = m_ast_builder.ToCompilerType(member_type);
+ PdbAstBuilder::RequireCompleteType(member_ct);
----------------
Are you sure about static member part? Something like `struct A; struct B {
static A a; };` will compile fine (unlike `struct A; struct B { A a; };`), so
I'd hope that the expression evaluator could handle an incomplete static
member. It would be better if `p B::a` produces something like `error: variable
has incomplete type 'A'` instead of printing an empty struct.
================
Comment at: lldb/test/Shell/SymbolFile/NativePDB/incomplete-tag-type.cpp:25
+B b;
+B b_array[3] = {};
+A C::static_a = A();
----------------
The `A a_array[]` case is more interesting, because here the class might be
(and probably will be) completed as a part of completing B. It would also be
better to use a different incomplete class for each test case, as a class can
be completed only once.
