This could be 'null' or the empty string, DIDescriptor::getStringField coalesces the two cases anyway so it's just a matter of legible/efficient representation. The change in behavior of the DICompileUnit::get* functions could be subsumed by the full verification check - but ideally that should just be an assertion if we could front-load the actual debug info metadata failure paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176907 91177308-0d34-0410-b5e6-96231b3b80d8
