In the DWARF reader it can happen that a function type being built is
canonicalized too early, before the type is done building. This leads
to some spurious type differences later at comparison time. It
typically happens when a sub-type of the function type refers to the
function type itself. We correctly handle similar cases for class
types, but not for function types. Oops.
This patch handles this case for function types in the dwarf reader
and in the abixml reader.
* src/abg-dwarf-reader.cc (die_function_type_map_type): New
typedef.
* ():
(read_context::die_wip_function_types_map_): New data member.
(read_context::{die_wip_function_types_map,
is_wip_function_type_die_offset}): New methods.
(build_function_type): Mark the function being built as "work in
progress".
(maybe_canonicalize_type): Do not early-canonicalize WIP function
types.
* src/abg-reader.cc (build_function_type): Mark the function being
built as "work in progress".
* tests/test-diff-dwarf-abixml.cc: New test harness.
* tests/Makefile.am: Add new test harness runtestdiffdwarfabixml
to the build system.
* tests/data/test-diff-dwarf-abixml/test0-pr19026-libvtkIOSQL-6.1.so.1:
New test binary input.
* tests/data/test-diff-dwarf-abixml/test0-pr19026-libvtkIOSQL-6.1.so.1.abi:
New test input.
* tests/data/Makefile.am: Add new test inputs to source
distribution.
* tests/data/test-read-dwarf/test17-pr19027.so.abi: Adjust.

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.
