The tool is based on different software stack for analysis of backward compatibility developed since 2009: https://github.com/lvc (ABI Compliance Checker, ABI Dumper, etc.) RedHat created an alternative libabigail tool in 2013. Implementation and reports are completely different. But anyway, two is better than one. Now we can verify reports of both tools by each other. The ABI Compliance Checker/ABI Dumper tools are mostly used in upstream currently (https://github.com/lvc/abi-tracker). The new pkg-abidiff interface for Linux maintainers is an effort to simplify the use of ABI Compliance Checker on RPM packages.
