In this problem report libabigail's DWARF reader wrongly looks up the
address of variables (that it got from DWARF) in the .bss section of
the ELF file. But then, in these files (generated by the Intel C++
compiler) the variables we are looking at have their addresses in the
.data1 section.
This patch changes the DWARF/ELF reader to make it look for variable
addresses in .data, .data1, .rodata and .bss sections, as it should
be.
* include/abg-dwarf-reader.h (elf_type::ELF_TYPE_RELOCATABLE): New
enumerator.
* src/abg-dwarf-reader.cc (find_section): Factorize this from ...
(find_text_section, find_bss_section): ... these.
(find_rodata_section, find_data_section, find_data1_section):
Define new static functions.
(elf_file_type): Move this static function definition up.
(read_context::{get_elf_file_type, address_is_in_section,
get_data_section_for_variable_address}): New member functions.
(read_context::maybe_adjust_fn_sym_address): Adjust comment.
Adjust to use the new
read_context::get_data_section_for_variable_address().
* tests/data/test-types-stability/pr19138-elf0: New test input
binary.
* tests/data/Makefile.am: Add the new test input binary to the
test suite.
* tests/test-types-stability.cc (elf_paths): Take it into account.

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.
