Usually, function DIEs (DW_TAG_subprogram) refer to the address of the underlying ELF symbol by using the DW_AT_low_pc attribute. However, there are cases where it does so by using the DW_AT_ranges attribute. In those cases, the first address of the sequence defined in the value of that attribute is the address of the ELF symbol. The problem is that the DWARF reader of Libabigail fails to get the address of the underlying ELF symbol when the DW_AT_low_pc attribute is missing. Rather, it should then look at the value of the DW_AT_ranges attribute instead. This is what this patch does. * src/abg-dwarf-reader.cc (read_context::get_first_address_from_DW_AT_ranges): Define new member function. (read_context::get_function_address): Use the new read_context::get_first_address_from_DW_AT_ranges here. * tests/data/test-diff-dwarf/PR25058-liblttng-ctl-report-1.txt: New reference test output. * tests/data/test-diff-dwarf/PR25058-liblttng-ctl.so: New test input binary. * tests/data/test-diff-dwarf/PR25058-liblttng-ctl2.10.so: New test input binary. * tests/data/Makefile.am: Add the new test materials above to source distribution. * tests/test-diff-dwarf.cc (in_out_specs): Add the new input test input binary files to this test harness.
