After fixing the interpretation of the DW_AT_bit_offset attribute for
offset of bit field data members, serialized abixml might now be
incompatible with versions of Libabigail that use the previous
interpretation.
That means that comparing an abixml file generated with previous
versions of Libabigail against a corpus resulting from an analysis
performed with the current version of libabigail might yield spurious
changes due to the differences in the way we now interpret the
DW_AT_bit_offset.
Hence, this patch bumps the version of abixml files emitted from now
on to "2.0". This version is deemed incompatible with the previous
"1.0" version.
Subsequently, an abixml file of the "1.0" format cannot be compared
against an abixml file of the "2.0" format, or against a binary
analyzed with a current version of Libabigail.
It's thus advised that abixml files of the "1.0" format version should
be re-generated with a current version of Libabigail, bumping their
format version number to the new "2.0".

This is the Application Binary Interface Generic Analysis and Instrumentation Library. It aims at constructing, manipulating, serializing and de-serializing ABI-relevant artifacts. The set of artifacts that we are intersted is made of quantities like types, variable, fonctions and declarations of a given library or program. For a given library or program this set of quantities is called an ABI corpus. This library aims at (among other things) providing a way to compare two ABI Corpora (apparently the plural of corpus is copora, heh, that's cool), provide detailed information about their differences, and help build tools to infer interesting conclusions about these differences. You are welcome to contribute to this project after reading the files CONTRIBUTING and COMMIT-LOG-GUIDELINES files in the source tree. Communicating with the maintainers of this project -- including sending patches to be include to the source code -- happens via email at libabigail@sourceware.org.
