llvm-project.git/llvm/test/Bitcode/DIGlobalVariableExpression2.ll.bc, branch main Unnamed repository; edit this file 'description' to name the repository. Fix bitcode upgrade for DIGlobalVariables with a var: field. 2017-02-08T17:44:43+00:00 Adrian Prantl aprantl@apple.com 2017-02-08T17:44:43+00:00 a5bf2d7003928e5ada8e22d4bbf0c776633eecab This is a follow-up to https://reviews.llvm.org/D29349. It turns out that NeedUpgradeToDIGlobalVariableExpression is always necessary when we encountered a version==0 record because it may always be referenced via a list of globals in a DICompileUnit. My tests weren't good enough to catch this though. To trigger this case, we need much older bitcode produced by LLVM around version 3.7. <rdar://problem/30404262> Differential Revision: https://reviews.llvm.org/D29693 llvm-svn: 294488
