Not really, the two primary ways I try to detect ABI breakage are using:

- the scripts under `libcxx/utils/sym_check/`. They provide a way to diff the symbols between two dylibs `sym_diff.py old-lib.so new-lib.so`.
- Compiling against an old library and swapping in a new library at runtime.

I also used libabigail for a while but it was a bit too noisy with false positives. It may be better now though.
