Trying to de-duplicate anonymous struct DIEs can lead to subtle issues, because there can be two different naming typedefs designating two anonymous structs that are equivalent, in the same translation unit. In that case, de-duplicating the two leaf anonymous structs DIEs leads to non-resolvable conflict. This patch avoids de-duplicating anonymous structs DIEs and rather de-duplicates (naming) typedefs. * include/abg-fwd.h (is_typedef): Remove the overloads for type_base_sptr and decl_base_sptr. Replace those with an overload for type_or_decl_base_sptr. * src/abg-ir.cc (is_typedef): Do the same for the definitions. * src/abg-dwarf-reader.cc (add_or_update_class_type) (add_or_update_union_type): Do not de-duplicate anonymous struct/union DIEs. (build_typedef_type): Try to de-duplicate typedefs DIEs. * tests/data/test-annotate/test17-pr19027.so.abi: Adjust. * tests/data/test-annotate/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise * tests/data/test-annotate/test21-pr19092.so.abi: Likewise. * tests/data/test-read-dwarf/PR22015-libboost_iostreams.so.abi: Likewise. * tests/data/test-read-dwarf/PR22122-libftdc.so.abi: Likewise. * tests/data/test-read-dwarf/test16-pr18904.so.abi: Likewise. * tests/data/test-read-dwarf/test17-pr19027.so.abi: Likewise. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise. * tests/data/test-read-dwarf/test21-pr19092.so.abi: Likewise. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Likewise.
