Hi,

We added a new opensuse-leap container tester to libabigail:
https://builder.sourceware.org/buildbot/#/builders/libabigail-opensuseleap-x86_64

But it fails the build with:

abg-dwarf-reader.cc: In function ‘bool abigail::dwarf_reader::is_type_tag(unsigned int)’:
abg-dwarf-reader.cc:6843:10: error: ‘DW_TAG_coarray_type’ was not declared in this scope
     case DW_TAG_coarray_type:
          ^~~~~~~~~~~~~~~~~~~
abg-dwarf-reader.cc:6843:10: note: suggested alternative: ‘DW_TAG_array_type’
     case DW_TAG_coarray_type:
          ^~~~~~~~~~~~~~~~~~~
          DW_TAG_array_type
abg-dwarf-reader.cc:6845:10: error: ‘DW_TAG_immutable_type’ was not declared in this scope
     case DW_TAG_immutable_type:
          ^~~~~~~~~~~~~~~~~~~~~
abg-dwarf-reader.cc:6845:10: note: suggested alternative: ‘DW_TAG_volatile_type’
     case DW_TAG_immutable_type:
          ^~~~~~~~~~~~~~~~~~~~~
          DW_TAG_volatile_type

DW_TAG_coarray_type and DW_TAG_immutable_type are two new DWARF5 tags,
not yet defined in libdw-0.168.

We could workaround that by checking and ignoring or redefining them.
But even then the testsuite fails various tests. I suspect because
there are various DWARF5 test files now.

Does it make sense try to make this work against such an old elfutils version?
Or should we simply not run a builder with this old an elfutils version?

elfutils 0.171 was the first version to officially support
DWARF5. Maybe that should be the minimum version for libabigail now?

The centos7 builder and debian-old-stable builders have elfutils 0.176
and are both green:
https://builder.sourceware.org/buildbot/#/builders/libabigail-debian-amd64
https://builder.sourceware.org/buildbot/#/builders/libabigail-centos-x86_64

Cheers,

Mark

P.S. There is now a dedicated buildbot@sourceware.org list (CCed) for
     any questions about the buildbot builders.
