abi-compliance-checker – a tool for checking backward binary/source-level compatibility of a shared C/C++ library (DSO):
A tool for checking backward binary and source-level compatibility of a C/C++ library. The tool checks header files and shared libraries of old and new versions and analyzes changes in API and ABI (ABI=API+compiler ABI) that may break binary and/or source compatibility: changes in calling stack, v-table changes, removed symbols, renamed fields, etc.
icheck – C interface ABI/API checker:
A tool for statically checking C interfaces for API and ABI changes. All changes to type declarations that can cause ABI changes should be detected, along with most API changes.
icheck is intended for use with libraries, as a method of preventing ABI drift.
shlib-compat – ABI compatibility checker for shared libraries with symbol versioning:
shlib-compat uses dwarf debugging symbols to recreate and compare definitions of exported
symbols, including function arguments and structural types.
Also you might be interested in the linux upstream tracker and linux abi tracker services. They are both powered by the abi-compliance-checker tool.
