From c96da8faa65b723899744b0fc5c23f4b286fcc02 Mon Sep 17 00:00:00 2001 From: Adrian Prantl Date: Fri, 22 Jan 2016 17:43:43 +0000 Subject: Module Debugging: Use a nonzero DWO id for precompiled headers. PCH files don't have a module signature and LLVM uses a nonzero DWO id as an indicator for skeleton / module CUs. This change pins the DWO id for PCH files to a known constant value. The correct long-term solution here is to implement a module signature that is an actual dterministic hash (at the moment module signatures are just random nonzero numbers) and then enable this for PCH files as well. llvm-svn: 258507 --- clang/test/Modules/ModuleDebugInfo.cpp | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'clang/test/Modules/ModuleDebugInfo.cpp') diff --git a/clang/test/Modules/ModuleDebugInfo.cpp b/clang/test/Modules/ModuleDebugInfo.cpp index a2b735b3b70..73443972409 100644 --- a/clang/test/Modules/ModuleDebugInfo.cpp +++ b/clang/test/Modules/ModuleDebugInfo.cpp @@ -8,7 +8,6 @@ // RUN: %clang_cc1 -triple %itanium_abi_triple -x objective-c++ -std=c++11 -debug-info-kind=limited -fmodules -fmodule-format=obj -fimplicit-module-maps -DMODULES -fmodules-cache-path=%t %s -I %S/Inputs -I %t -emit-llvm -o %t.ll -mllvm -debug-only=pchcontainer &>%t-mod.ll // RUN: cat %t-mod.ll | FileCheck %s // RUN: cat %t-mod.ll | FileCheck --check-prefix=CHECK-NEG %s -// RUN: cat %t-mod.ll | FileCheck --check-prefix=CHECK-DWO %s // PCH: // RUN: %clang_cc1 -triple %itanium_abi_triple -x c++ -std=c++11 -emit-pch -fmodule-format=obj -I %S/Inputs -o %t.pch %S/Inputs/DebugCXX.h -mllvm -debug-only=pchcontainer &>%t-pch.ll @@ -22,7 +21,7 @@ // CHECK: distinct !DICompileUnit(language: DW_LANG_{{.*}}C_plus_plus, // CHECK-SAME: isOptimized: false, // CHECK-SAME-NOT: splitDebugFilename: -// CHECK-DWO: dwoId: +// CHECK: dwoId: // CHECK: !DICompositeType(tag: DW_TAG_enumeration_type, name: "Enum" // CHECK-SAME: identifier: "_ZTSN8DebugCXX4EnumE") -- cgit v1.2.3
