ABI Compliance Checker (ABICC) is a tool for checking backward binary and source-level compatibility of a C/C++ library. The tool analyzes changes in API/ABI (ABI=API+compiler ABI) that may break binary compatibility and/or source compatibility: changes in calling stack, v-table changes, removed symbols, renamed fields, etc. The tool can create and compare ABI dumps for header files and shared objects of a library. The ABI dump for a library can also be created by the ABI Dumper tool if shared objects include debug-info.
