@@ -1,3 +1,41 @@ +Version 0.171 + +DWARF5 and split dwarf, including GNU DebugFission, are supported now. +Data can be read from the new DWARF sections .debug_addr, .debug_line_str, +.debug_loclists, .debug_str_offsets and .debug_rnglists. Plus the new +DWARF5 and GNU DebugFission encodings of the existing .debug sections. +Also in split DWARF .dwo (DWARF object) files. This support is mostly +handled by existing functions (dwarf_getlocation*, dwarf_getsrclines, +dwarf_ranges, dwarf_form*, etc.) now returning the data from the new +sections and data formats. But some new functions have been added +to more easily get information about skeleton and split compile units +(dwarf_get_units and dwarf_cu_info), handle new attribute data +(dwarf_getabbrevattr_data) and to keep references to Dwarf_Dies +that might come from different sections or files (dwarf_die_addr_die). + +Not yet supported are .dwp (Dwarf Package) and .sup (Dwarf Supplementary) +files, the .debug_names index, the .debug_cu_index and .debug_tu_index +sections. Only a single .debug_info (and .debug_types) section are +currently handled. + +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 of + an alt attribute FORM 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. + +There were various improvements to build on Windows. +The sha1 and md5 implementations have been removed, they weren't used. + Version 0.170 libdw: Added new DWARF5 attribute, tag, character encoding, language code, |
