[Amjad Aboud via llvm-commits]

aaboud added a comment.

I will add the following test: Clang/test/Codegen/debug-info-imported-entity.cpp

  // RUN: %clang_cc1 -triple x86_64-unk-unk -o - -emit-llvm -debug-info-kind=limited %s | FileCheck %s
  
  namespace std { class A; }
  using std::A; using ::A;
  
  // CHECK: [[CompileUnit:![0-9]+]] = distinct !DICompileUnit({{.+}} imports: [[Imports:![0-9]+]])
  // CHECK: [[Imports]] = !{[[ImportedEntity:![0-9]+]]}
  // CHECK: [[ImportedEntity]] = !DIImportedEntity(tag: DW_TAG_imported_declaration, scope: [[CompileUnit]], entity: !"_ZTSSt1A", line: 4)
