That's since been fixed.llvm-svn: 349968 List of files: /llvm-project-15.0.7/llvm/test/DebugInfo/Inputs/dwarfdump-test.elf-x86-64.debuglink Fri, 21 Dec 2018 22:25:01 +0000 David Blaikie <dblaikie@gmail.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/DebugInfo/Inputs/dwarfdump-test.elf-x86-64.debuglink#6c933a2b Revert "DebugInfo: Assume an absence of ranges or high_pc on a CU means the CU is empty (devoid of code addresses)"This reverts commit r349333.
