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.
