Do you need to set the access here? Isn't there some code that is triggered earlier and set this?

Unfortunately no, it has to be set manually.

Some comments inline.

DC is imported first so it is possible to have a failed import and non-null DC. The assertion here seems to be incorrect.

4276

I think this should be placed into a separate function: there are many cases that can require attribute import so this code can be reused.

This will assert if isImplicit() method returns true. In such case, Base should be nullptr.

5820

Are any of source parts can be null? Do we need to check them all?

5824

I have placed a function template for import of TemplateArgumentListInfo into D38845.

5848

Should we fail if nullptr was returned?

Could you please format the code with indents?

Updates based on comments.

Actually, I just realized it is part of the ´Importer.Imported´ function call as well, so this is unnecessary.

Left some unformatted lines in the previous version. Fixed.

Since E->getFirstQualifierFoundInScope() can be null, it does not necessarily mean that it should fail. However, I checked it in a more structured way above if its OK.

Hi Peter. All is almost OK but I have some doubts about one of checking conditions.

lib/AST/ASTImporter.cpp
5831

Did you mean _!_E->getMember.isEmpty()? If so, you can rewrite the code as if (E->getMember() && !Name).

Updating the usage of ImportTemplateArgumentListInfo.

I still have questions about this line. I strongly believe that we should fail if the source DeclarationName is non-empty and the result is empty. This line fails if they are both empty which seems to be a correct case for me.

Yepp, I am not exactly sure how I managed to do it, but I've missed this comment last time. Fixed it.

Peter, this condition still looks inverted to me. Am I missing something?

Nope, that was me. If this (and the dependencies) are looking good, I can commit them as well (added the dependencies ^^).

LGTM, thank you!

It was reverted due to tests failures on windows build bots.

Peter, could you please fix the tests to correspond new format? I've made them pass with some changes (in inline comment).

  1. For these two tests, C should be struct because t is a private member and is inaccessible from declToImport().
  2. An additional line void foo() { declToImport<int>(); } should resolve the issue for both tests.

Sorry for the noise, I have fixed the patch and re-committed it, but forgot to remove "Request changes" status.
