From fed4f399d3a9b8381d9d32e7aa928855b11d7485 Mon Sep 17 00:00:00 2001 From: Adrian Prantl Date: Fri, 28 Apr 2017 22:25:46 +0000 Subject: [PATCH] Remove line and file from DINamespace. Fixes the issue highlighted in http://lists.llvm.org/pipermail/cfe-dev/2014-June/037500.html. The DW_AT_decl_file and DW_AT_decl_line attributes on namespaces can prevent LLVM from uniquing types that are in the same namespace. They also don't carry any meaningful information. rdar://problem/17484998 Differential Revision: https://reviews.llvm.org/D32648 llvm-svn: 301706 --- llvm/include/llvm/IR/DIBuilder.h | 6 ++-- llvm/include/llvm/IR/DebugInfoMetadata.h | 37 ++++++++++------------ llvm/lib/AsmParser/LLParser.cpp | 4 +-- llvm/lib/Bitcode/Reader/MetadataLoader.cpp | 12 ++++--- llvm/lib/Bitcode/Writer/BitcodeWriter.cpp | 2 -- llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp | 5 --- llvm/lib/CodeGen/AsmPrinter/DwarfUnit.h | 1 - llvm/lib/IR/AsmWriter.cpp | 2 -- llvm/lib/IR/DIBuilder.cpp | 11 +++++-- llvm/lib/IR/DebugInfoMetadata.cpp | 12 +++---- llvm/lib/IR/LLVMContextImpl.h | 17 ++++------ llvm/test/Assembler/dinamespace.ll | 6 ++-- llvm/test/Bitcode/DINamespace.ll | 4 +-- llvm/test/CodeGen/X86/stack-protector-dbginfo.ll | 2 +- llvm/test/DebugInfo/COFF/cpp-mangling.ll | 2 +- llvm/test/DebugInfo/COFF/scopes.ll | 4 +-- llvm/test/DebugInfo/Generic/dwarf-public-names.ll | 2 +- llvm/test/DebugInfo/Generic/namespace.ll | 22 ++++++------- .../Generic/namespace_function_definition.ll | 2 +- .../namespace_inline_function_definition.ll | 2 +- llvm/test/DebugInfo/X86/dwarf-linkage-names.ll | 2 +- llvm/test/DebugInfo/X86/dwarf-public-names.ll | 4 +-- llvm/test/DebugInfo/X86/generate-odr-hash.ll | 8 ++--- llvm/test/DebugInfo/X86/gnu-public-names-tu.ll | 2 +- llvm/test/DebugInfo/X86/gnu-public-names.ll | 10 +++--- llvm/test/DebugInfo/X86/inline-namespace.ll | 4 +-- .../DebugInfo/X86/lexical-block-file-inline.ll | 2 +- llvm/test/DebugInfo/X86/multiple-at-const-val.ll | 2 +- llvm/test/DebugInfo/X86/parameters.ll | 2 +- llvm/test/DebugInfo/X86/pr19307.ll | 8 ++--- llvm/test/DebugInfo/X86/union-template.ll | 2 +- llvm/test/Linker/2011-08-18-unique-class-type.ll | 2 +- llvm/test/Linker/2011-08-18-unique-class-type2.ll | 2 +- llvm/test/Linker/pr26037.ll | 2 +- llvm/test/ThinLTO/X86/debuginfo-cu-import.ll | 2 +- llvm/unittests/IR/MetadataTest.cpp | 23 +++----------- 36 files changed, 102 insertions(+), 130 deletions(-) diff --git a/llvm/include/llvm/IR/DIBuilder.h b/llvm/include/llvm/IR/DIBuilder.h index 0656878..4afb5d9 100644 --- a/llvm/include/llvm/IR/DIBuilder.h +++ b/llvm/include/llvm/IR/DIBuilder.h @@ -632,11 +632,9 @@ namespace llvm { /// parent scope. /// \param Scope Namespace scope /// \param Name Name of this namespace - /// \param File Source file - /// \param LineNo Line number /// \param ExportSymbols True for C++ inline namespaces. - DINamespace *createNameSpace(DIScope *Scope, StringRef Name, DIFile *File, - unsigned LineNo, bool ExportSymbols);
