From: Frederic Riss Date: Fri, 13 Mar 2015 18:35:39 +0000 (+0000) Subject: [dsymutil] Fix location cloning for newer dwarf versions. X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3a5c1173c5fa782f9fff59b7e867bfac6ab03a7d;p=oota-llvm.git [dsymutil] Fix location cloning for newer dwarf versions. The typo got unnoticed because we were testing only on Dwarf 2. Add a Dwarf4 test that exercises the code path, and also tests some newer FORMs that the other test doesn't cover. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232191 91177308-0d34-0410-b5e6-96231b3b80d8 --- diff --git a/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64 b/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64 new file mode 100755 index 00000000000..7e7ba2f48f8 Binary files /dev/null and b/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64 differ diff --git a/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64.o b/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64.o new file mode 100644 index 00000000000..307a6813092 Binary files /dev/null and b/test/tools/dsymutil/Inputs/basic-lto-dw4.macho.x86_64.o differ diff --git a/test/tools/dsymutil/X86/basic-lto-dw4-linking-x86.test b/test/tools/dsymutil/X86/basic-lto-dw4-linking-x86.test new file mode 100644 index 00000000000..5f85952ba20 --- /dev/null +++ b/test/tools/dsymutil/X86/basic-lto-dw4-linking-x86.test @@ -0,0 +1,94 @@ +RUN: llvm-dsymutil -o -
