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/Linker/Inputs/subprogram-linkonce-weak.ll | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'llvm/test/Linker/Inputs/subprogram-linkonce-weak.ll') diff --git a/llvm/test/Linker/Inputs/subprogram-linkonce-weak.ll b/llvm/test/Linker/Inputs/subprogram-linkonce-weak.ll index f5399e244a9..85227d3ac29 100644 --- a/llvm/test/Linker/Inputs/subprogram-linkonce-weak.ll +++ b/llvm/test/Linker/Inputs/subprogram-linkonce-weak.ll @@ -10,7 +10,7 @@ declare i32 @fastadd(i32, i32) !0 = !{i32 2, !"Debug Info Version", i32 3} !llvm.dbg.cu = !{!1} -!1 = !DICompileUnit(language: DW_LANG_C99, file: !2, subprograms: !{!3}, emissionKind: 1) +!1 = distinct !DICompileUnit(language: DW_LANG_C99, file: !2, subprograms: !{!3}, emissionKind: 1) !2 = !DIFile(filename: "foo.c", directory: "/path/to/dir") !3 = !DISubprogram(file: !2, scope: !2, line: 51, name: "foo", function: i32 (i32, i32)* @foo, type: !4) !4 = !DISubroutineType(types: !{}) -- cgit v1.2.3
