From 43e008174072301cca77524027ddb74d1d8b604a Mon Sep 17 00:00:00 2001 From: Adrian Prantl Date: Tue, 19 Jan 2016 23:42:53 +0000 Subject: [PATCH] Module Debugging: Don't emit external type references to anonymous types. Even if they exist in the module, they can't be matched with the forward declaration in the object file. llvm-svn: 258251 --- clang/lib/CodeGen/CGDebugInfo.cpp | 5 +++-- clang/test/Modules/ExtDebugInfo.cpp | 9 +++++++++ 2 files changed, 12 insertions(+), 2 deletions(-) diff --git a/clang/lib/CodeGen/CGDebugInfo.cpp b/clang/lib/CodeGen/CGDebugInfo.cpp index 2511b249f0f5..fa501fce756c 100644 --- a/clang/lib/CodeGen/CGDebugInfo.cpp +++ b/clang/lib/CodeGen/CGDebugInfo.cpp @@ -1536,8 +1536,9 @@ static bool shouldOmitDefinition(CodeGenOptions::DebugInfoKind DebugKind, const RecordDecl *RD, const LangOptions &LangOpts) { // Does the type exist in an imported clang module? - if (DebugTypeExtRefs && RD->isFromASTFile() && RD->getDefinition()) - return true; + if (DebugTypeExtRefs && RD->isFromASTFile() && RD->getDefinition() && + RD->isExternallyVisible()) + return true; if (DebugKind > CodeGenOptions::LimitedDebugInfo) return false; diff --git a/clang/test/Modules/ExtDebugInfo.cpp b/clang/test/Modules/ExtDebugInfo.cpp index 6c5bd559fc99..101b0f1e16b2 100644 --- a/clang/test/Modules/ExtDebugInfo.cpp +++ b/clang/test/Modules/ExtDebugInfo.cpp @@ -84,4 +84,13 @@ void foo() { // CHECK: !DICompositeType(tag: DW_TAG_enumeration_type, scope: ![[NS]], // CHECK-SAME: line: 16 +// CHECK: !DIGlobalVariable(name: "GlobalUnion", +// CHECK-SAME: type: ![[GLOBAL_UNION:[0-9]+]] +// CHECK: ![[GLOBAL_UNION]] = !DICompositeType(tag: DW_TAG_union_type, +// CHECK-SAME: elements: !{{[0-9]+}}) +// CHECK: !DIGlobalVariable(name: "GlobalStruct", +// CHECK-SAME: type: ![[GLOBAL_STRUCT:[0-9]+]] +// CHECK: ![[GLOBAL_STRUCT]] = !DICompositeType(tag: DW_TAG_structure_type, +// CHECK-SAME: elements: !{{[0-9]+}}) + // CHECK: !DIImportedEntity(tag: DW_TAG_imported_declaration, scope: !0, entity: !"_ZTSN8DebugCXX6StructE", line: 24)
