The abidw utility produces an XML document describing the ABI of a given ELF shared library, which makes it very useful when doing library development. Unfortunately, it is ELF only.
Is anyone aware of a utility to obtain the same sort of information about MACH-O dylibs? For the particular application I have in mind, I don't much care about the XML'ness of the output (I'm MD5'ing the abidw output anyway), but I do care that I get different output if a re-linked dylib exposes a new ABI, and, more importantly, that I get the same output if the ABI hasn't changed.
Are there any utilities for extracting an ABI definition or hash from a dylib on OS X?
In the end, years later, it turns out that the effect can mostly be achieved with the tapi tool on MacOS.
