Sometimes when amending a C++ class to add new members or properties to it as directed by the DWARF debug information, we can end-up with discrepancies related to declaration-only-ness. That is, an instances of a given type Foo can be wrongly assigned declaration-only-ness that should have been only carried by another instance Foo. Then, later, comparing two pointers to Foo might wrongly lead to spurious reported changes due to the spurious differences of declaration-only-ness in two instances of Foo. By fixing the setting of the declaration-only-ness, especially when amending a C++ class this patch fixes that spurious change detected. * src/abg-dwarf-reader.cc (add_or_update_class_type): When creating a class, set declaration-only-ness unconditionally. When updating the class however, only set the declaration-only-ness when the current one is not consistent with the size of the class. * tests/data/test-annotate/test14-pr18893.so.abi: Adjust. * tests/data/test-annotate/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise. * tests/data/test-annotate/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/data/test-read-dwarf/test14-pr18893.so.abi: Likewise. * tests/data/test-read-dwarf/test19-pr19023-libtcmalloc_and_profiler.so.abi: Likewise. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/data/test-read-dwarf/test22-pr19097-libstdc++.so.6.0.17.so.abi: Likewise.
