- elfclassify: New tool to analyze ELF objects.
- readelf: Print DW_AT_data_member_location as decimal offset.
Decode DW_AT_discr_list block attributes.
- libdw: Add DW_AT_GNU_numerator, DW_AT_GNU_denominator and DW_AT_GNU_bias.
- libdwelf: Add dwelf_elf_e_machine_string.
dwelf_elf_begin now only returns NULL when there is an error
reading or decompressing a file. If the file is not an ELF file
an ELF handle of type ELF_K_NONE is returned.
- backends: Add support for C-SKY.
- More fixes for crashes and hangs found by afl-fuzz. In particular
various functions now detect and break infinite loops caused by bad
DIE tree cycles.
- readelf: Will now lookup the size and signedness of constant value
types to display them correctly (and not just how they were encoded).
- libdw: New function dwarf_next_lines to read CU-less .debug_line data.
dwarf_begin_elf now accepts ELF files containing just .debug_line
or .debug_frame sections (which can be read without needing a DIE
tree from the .debug_info section).
Removed dwarf_getscn_info, which was never implemented.
- backends: Handle BPF simple relocations.
The RISCV backends now handles ABI specific CFI and knows about
RISCV register types and names.
- New upstream release.
- DWARF5 and split dwarf, including GNU DebugFission, support.
- readelf: Handle all new DWARF5 sections.
--debug-dump=info+ will show split unit DIEs when found.
--dwarf-skeleton can be used when inspecting a .dwo file.
Recognizes GNU locviews with --debug-dump=loc.
- libdw: New functions dwarf_die_addr_die, dwarf_get_units,
dwarf_getabbrevattr_data and dwarf_cu_info.
libdw will now try to resolve the alt file on first use
when not set yet with dwarf_set_alt.
dwarf_aggregate_size() now works with multi-dimensional arrays.
- libdwfl: Use process_vm_readv when available instead of ptrace.
- backends: Add a RISC-V backend.
Resolves: #1365812
eu-stack killed by SIGABRT processing gcore created core file.
Resolves: #1352232
libelf: Can't add Program Header when e_type is set to OS/Proc specific.
- libdw: Fix for handling huge .debug_aranges section. (#638432)
- libdwfl: Fix for handling prelinked DSO with separate debug file. (#652857)
- findtextrel: Fix diagnostics to work with usual section ordering.
