            Bug ID: 21792
           Summary: Decode DWARF5 in eu-readelf
           Product: elfutils
           Version: unspecified
            Status: NEW

Created attachment 10274
  --> https://sourceware.org/bugzilla/attachment.cgi?id=3D10274&action=3Ded=
it
clang compiled object that includes the example above

We are starting to use Clang 4.0.0 at LLNL and it is emitting some DWARF5
opcodes. Please add DWARF5 decoding to eu-readelf.

For example:
#include <string>
#include <vector>

std::vector<std::string> var;

and tangentially I saw something in the DWARF which neither readelf or
eu-readelf understands.
[   7e1]      namespace
               name                 (strp) "__cxx11"
               decl_file            (data1) 1
               decl_line            (data2) 2214
               ??? (0x89)           (flag_present) yes


Since clang is already emitting some DWARF5 we should at least be able to
decode what it is emitting reliably.
