It appears that two different types from two different translation units might have the same name in a DSO, like in the example of this bug. This violates the One Definition Rule, which we rely on to go fast, and more importantly, it introduces type canonicalization errors. This patch recognizes more of these ODR violation cases by looking at the size of the types. That is, if two types (from the same DSO) with the same name have different sizes, then they are different. * src/abg-ir.cc (type_base::get_canonical_type_for): Look at the size of types with the same name which could be considered ODR-equal, to spot possible violations that would induce a type canonicalization error. * tests/data/test-read-dwarf/test21-pr19092.so: New test input binary. * tests/data/test-read-dwarf/test21-pr19092.so.abi: New reference abixml for the binary above. * tests/data/Makefile.am: Add the new test input above to source distribution. * tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Adjust. * tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise. * tests/data/test-read-dwarf/test20-pr19025-libvtkParallelCore-6.1.so.abi: Likewise. * tests/test-read-dwarf.cc (int_out_specs): Add the two test input above.

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
