Ok, sounds good.

This is deliberate. During construction of ASTImporter the minimal import
flag is set. And then when ASTImporter::ImportDefinition is called, it will
do a full import, even
Hi Jaroslav,
Thank you for digging into this. I think it may be possible to not eagerly
import a RecordDecl. Perhaps we could control that from
clang::ASTNodeImporter::VisitPointerType and instead of a full import we
could just do a minimal import for the PointeeType always. Similarly to
Hi Jaroslav,
Thanks for working on this. Still, there are things that are unclear for me.
I see that `LayoutRecordType` is called superfluously during the second
evaluation of `c2.x`, ok.
But, could you explain why LLDB is calling that multiple times? Maybe it
thinks a type is not completed
Hi,
Thank you guys for coming to the round table. I am trying to summarize what

We agreed that this is something that would be incredibly problematic to

Hi,
At the upcoming LLVM Dev Conf, we will have a round table discussion for
ASTImporter, right after the ASTImporter Tutorial.
The time slot for the round table is Wednesday, Oct 23 2:55-4:00.
I have gathered things about possible future work and improvements, bring
your own topic to discuss!

Hi,
I am planning to submit a talk about ASTImporter to the upcoming Dev
Meeting at October 22-23, 2019.
I'd like to talk about
- the API,
- how it is used in CTU analysis and in LLDB,
- internal subtleties and difficulties (Error handling, ExternalASTSource,
...)
The goal would be to attract
Some more info: I've stopped lldb (with the system lldb) when
" Process::SetExitStatus (status=-1 (0x), description="Error 1")"
is logged and gathered some more information.
Is it possible that some packet types are not implemented?

Perhaps after "sudo /usr/sbin/DevToolsSecurity --enable" a reboot is
required, but could not find anything official about that.

I'd like to fork from 7.0.0 final but I got confused:

Lang,
I've done some more research on this and here is what I've found so far.
LLDB uses the ExternalASTSource interface and it provides its own
implementation for it (lldb_private::ClangASTSource).
ClangASTSource is being used in at least 3 modes (all of these uses
the ASTImporter):
(1) to do a

if (!Method->isImplicit()) {

return false;
Hi Lang, Alexey,
I dug deeper into this and it seems like the issue happens only when a
**minimal** import is used. LLDB uses the minimal import. CrossTU
static analyzer uses the normal mode.
In normal import mode, in `ImportDeclContext` we do import all the
methods in the correct order. However,

I'd like to run the tests, when LLVM, Clang and LLDB are all built with ASAN.

Maybe the LLDB build does not respect the global -DLLVM_USE_SANITIZER

Of course, I think there is no need to have different functions which

I think it is a very good idea to exploit [[nodiscard]] .
On the other hand I find a bit misleading some of the names of these
functions. `importCastedNonNull` does a simple `cast<>` inside, thus
perhaps a name `importAndCast` would better explain what happens.
Similarly, instead of
An other idea, couldn't we just pass the cast operation as a template
template parameter?
