Turns out that DW_AT_ranges_base attribute sets the offset for DW_AT_ranges values specified in the .dwo file, but not for DW_AT_ranges specified in the skeleton compile unit DIE in the main executable. This is extremely confusing, and would hopefully be fixed in DWARF-5 when it's finalized. For now this behavior makes sense, as otherwise Fission would break DWARF consumers who doesn't know anything about DW_AT_ranges_base. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@210809 91177308-0d34-0410-b5e6-96231b3b80d8
