From 55ca964e944b610bfa09dd52490772b3d9f92fea Mon Sep 17 00:00:00 2001 From: "Duncan P. N. Exon Smith" Date: Mon, 3 Aug 2015 17:26:41 +0000 Subject: DI: Disallow uniquable DICompileUnits Since r241097, `DIBuilder` has only created distinct `DICompileUnit`s. The backend is liable to start relying on that (if it hasn't already), so make uniquable `DICompileUnit`s illegal and automatically upgrade old bitcode. This is a nice cleanup, since we can remove an unnecessary `DenseSet` (and the associated uniquing info) from `LLVMContextImpl`. Almost all the testcases were updated with this script: git grep -e '= !DICompileUnit' -l -- test | grep -v test/Bitcode | xargs sed -i '' -e 's,= !DICompileUnit,= distinct !DICompileUnit,' I imagine something similar should work for out-of-tree testcases. llvm-svn: 243885 --- llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll') diff --git a/llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll b/llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll index 958f12199d0..0ca46ccf97b 100644 --- a/llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll +++ b/llvm/test/DebugInfo/X86/stmt-list-multiple-compile-units.ll @@ -81,7 +81,7 @@ entry: !llvm.dbg.cu = !{!0, !10} !llvm.module.flags = !{!25} -!0 = !DICompileUnit(language: DW_LANG_C99, producer: "clang version 3.3", isOptimized: false, emissionKind: 1, file: !23, enums: !1, retainedTypes: !1, subprograms: !3, globals: !1, imports: !1) +!0 = distinct !DICompileUnit(language: DW_LANG_C99, producer: "clang version 3.3", isOptimized: false, emissionKind: 1, file: !23, enums: !1, retainedTypes: !1, subprograms: !3, globals: !1, imports: !1) !1 = !{} !3 = !{!5} !5 = !DISubprogram(name: "test", line: 2, isLocal: false, isDefinition: true, virtualIndex: 6, flags: DIFlagPrototyped, isOptimized: false, scopeLine: 3, file: !23, scope: !6, type: !7, function: i32 (i32)* @test, variables: !1) @@ -89,7 +89,7 @@ entry: !7 = !DISubroutineType(types: !8) !8 = !{!9, !9} !9 = !DIBasicType(tag: DW_TAG_base_type, name: "int", size: 32, align: 32, encoding: DW_ATE_signed) -!10 = !DICompileUnit(language: DW_LANG_C99, producer: "clang version 3.3 (trunk 172862)", isOptimized: false, emissionKind: 1, file: !24, enums: !1, retainedTypes: !1, subprograms: !11, globals: !1, imports: !1) +!10 = distinct !DICompileUnit(language: DW_LANG_C99, producer: "clang version 3.3 (trunk 172862)", isOptimized: false, emissionKind: 1, file: !24, enums: !1, retainedTypes: !1, subprograms: !11, globals: !1, imports: !1) !11 = !{!13} !13 = !DISubprogram(name: "fn", line: 1, isLocal: false, isDefinition: true, virtualIndex: 6, flags: DIFlagPrototyped, isOptimized: false, scopeLine: 1, file: !24, scope: !14, type: !7, function: i32 (i32)* @fn, variables: !1) !14 = !DIFile(filename: "simple2.c", directory: "/private/tmp") -- cgit v1.2.3
