It turns out that using a size_t to serialize an enumerator is not
enough to represent things like enum foo {value = -3}; We need to
represent it using ssize_t.
Also, the patch avoids early canonicalization (when reading DWARF) of
types that refer to themselves. This was leading to type degradation
(serializing the type from IR to abixml and de-serializing it back to
IR leads to a different type).
* include/abg-ir.h (enum_type_decl::enumerator::get_value()):
Change the type of this from size_t to ssize_t.
* src/abg-ir.cc (enum_type_decl::enumerator::get_value): Do the
same on the definition side.
(non_canonicalized_subtype_detector::visit_begin): If a type
refers to itself, late canonicalize it to have a similar hashing
result as what the abixml reader does.
* src/abg-reader.cc (build_enum_type_decl): Use ssize_t to read
the value of enumerators.
* tests/data/test-read-dwarf/test13-pr18894.so.abi: New test input.
* tests/data/Makefile.am: Add the new test inputs above to source
distribution.
* tests/test-read-dwarf.cc (in_out_specs): Add new test inputs.
* tests/data/test-read-dwarf/test9-pr18818-clang.so.abi: Adjust.
* tests/data/test-read-dwarf/test10-pr18818-gcc.so.abi: Likewise.
* tests/data/test-read-dwarf/test11-pr18828.so.abi: Likewise.
* tests/data/test-read-dwarf/test12-pr18844.so.abi: Likewise.

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 comparing two ABI Corpuses, 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.
